The Electric Sky 300 (AKA the ES 300 V3) is the crown jewel of the Green Sunshine Company and upgraded version of Electric Sky 300 (ES 300) V2  It’s arguably the best LED grow light (300 watt) in the market and has been conceived for both the sincere home grower and the skilled professional simultaneously.

So, What Makes the Electric Sky 300 V3 the BEST?

There are several reasons why the ES300 is considered to be one of the best LED grow lights (300 watt) going around.

1. Cutting-Edge Wideband Spectrum
One of the most radically innovative aspects of the Electric Sky es300 is the fact that it produces a wideband color output. This means that your plants receive a continuous range of color through infrared which stimulates more growth centers in your crop. What all this translates to is faster growth from plants in the vegetative growth phase and rapidly flourishing flowers; thus resulting in greater yields in record time. To learn more about the science behind this technology, scroll down below.

2. Rectangular Form Factor

This is a simple but effective measure taken by the manufacturers. The Electric Sky es300’s rectangular form factor allows for it to fit into grow tents easily as well as lending itself to be scaled for large rooms. Commercial growers can effortlessly fit as many units as they need into their production spaces.

3. Full-Body Heatsink for Silent Cooling

The Electric Sky comes with a full-body aluminum heatsink. This enables it to passively cool without the need for any moving parts to be broken down.

4. Dimmable

The ES300 has a large dynamic range and can be completely dimmed as required. Also, depending on what you need, you can choose to regulate each unit independently or hook them up to each other so that you can control all of them using just one switch.

5. Linear Optics

A lot of the energy in regular grow lights goes to waste. The Electric Sky es300 avoids this problem with its linear lenses. These lenses focus light directly on the plants, thereby increasing energy efficiency.

The Electric Sky sends light in two directions.

  • Firstly, it focuses the light downwards so that objects right next to the plant outside of the light’s purview don’t receive much light but the plants themselves do as they’re directly under the light.
  • Secondly, these linear lenses send light in a cross pattern which allows for better canopy penetration. Another benefit of this is that the light is softened up just so, which lets the plants grow closer to the light without burning up.

Thus, the lenses give you precise control over the light in your garden giving you the flexibility to grow how you need to.

6. Suitable for All Types of Setups

Continuing on from the previous point, the spectacular lenses on the Electric Sky es300 lends itself to all forms of setups be they large rooms, grow tents, and aisle or rack setups.

  • Large Grow Rooms: In large grow rooms, the linear lenses of the ES300, assist with light uniformity. It does this by keeping the light going under every unit unvarying. Thus the edges of the garden are as bright as the center and there are no hotspots created anywhere in the entire space.
  • Aisle or Rack Setups: In aisle or rack setups, the Electric Sky keeps the lights trained on the plants and it doesn’t spill onto the aisles or the walls. Even your eyes are protected while you’re working because there’s no undesired light in your eye line.
  • Grow Tent Setups: In grow tents, you have the option of altering the height of each Electric Sky unit as you see fit. That could mean adjusting it for the growing canopy or any other reason. The lenses can be accurately adjusted: the angle and the intensity can be exactly modified by placing each ES 300 unit where it needs to be.

* If standard white LEDs were used, the Umol/J would read 2.2. Wideband diodes create near red and infrared light above 680nm, critical nutrients to plant growth, at a slightly lower “electrical efficiency”, but greater overall “plant efficiency”.

The Science Behind Why the Electric Sky es300 is the Best LED Grow Light

The Green Sunshine Company Electric Sky V2 wideband led grow light is 20% more luminous than other grow lights even when using the same wattage of 300 W. One could say that it’s literally brilliant.

With its amazing spectrum projection coupled with its even light distribution, the ES300 simulates the sun’s magnificence more than any other full-spectrum light.

This is interesting because the Electric Sky can provide better results than an HID system even though it has 40% less power and generates 50% less heat. That means the ES300 packs 500 watts of HID growing power into a more efficient system.

So How Does the Electric Sky ES300 Light Manage to Do This?

The answer lies in a few genius pieces of tech. Namely:

  1. TRUE 330 W wattage. This is important because most lights don’t actually give you the full advertised wattage. More on this in a bit!
  2. The patent-pending GS1 spectrum wideband LED lights. More on this right below!
  3. The linear lenses which provide two types of lighting – downward lighting, in a way that directs all that precious light to the plants and NOT other places; and more importantly, cross pattern lighting, for canopy penetration AND to allow for maximum growth without burning due the softening of the light.
  4. All the rest of the tech: the rectangular form factor which maximizes the grow area, the full-body heatsink for passive cooling which is super efficient, and the flexible dimmer with an amazing dynamic range giving you the customizability you crave.

So, numbers 3 and 4, are relatively self-explanatory. These are smart decisions by a smart company that understands growing the way only growers can: better lights for better growing, additional effectual tech to complement it all; it all just fits and makes total sense.

So, onto numbers 1 and 2.

TRUE Wattage

In your research as a grower, you’ll find that some LED lights advertise a peculiarly massive wattage output in comparison to what their actual power rating is. In some cases, if you snoop around more, you’ll find the truth listed under something called “true wattage output”.

The fact that this is hidden is extremely disingenuous – essentially trying to trick you into buying a product that cannot do what it claims to do.

In fact, apart from the duplicity, you’ll find that a number of these cheap LED lights are less efficient watt-for-watt than conventional bulb lighting, and may even underperform when compared to them.

Which is why, just by providing a TRUE 330 watts, the Electric Sky 300 v3 wideband led grow light outperforms all the LED grow lights out there.

Why a Wideband Color Output is Better for Plant Growth

LED lights save energy. Everyone knows that. But LED lights can also provide a spectrum for excellent plant growth.

There exists a custom of using LED grow lights that are just “white” or “purple”. Also, other “full-spectrum” LEDs are not what they say they are. Essential colors are left out, or in an attempt to utilize the least power on paper, the spectrum isn’t full. It’s partial at best.

But here’s the kicker: plants can sense this.

Plants are sensitive to a wide range of colors in their environment and they genuinely need this to grow well.

The Electric Sky es300’s patent-pending GS1 wideband spectrum duplicates some of the Sun’s infrared wavelengths helping plants grow better. A balanced color ratio also guides plants into growing in a particular shape that yields maximum results.

This special color ratio stimulates photosystems 1 and 2, increasing leaf sizes and thus developing extremely fast vegetative growth rates with high flowering yields. The kind of wideband spectrum used in the ES300 is more efficient for plant growth per photon than white LEDs. In fact, some studies suggest up to 25% greater yield due to the activation of the plant’s photosystems.

The Emerson Effect:

This distinct high-dosage of near-infrared light helps plants make more effective use of the light available to it, and hence grow faster and better. This effect is known as the Emerson Effect.

Robert Emerson, in his 1957 paper, observed that:

  1. When plants are shown light with a wavelength greater than 680 nm, only one photosystem is activated.
  2. When plants are exposed to light with a wavelength lesser than 680 nm, the photosynthesis rate was reduced significantly.
  3. But when plants are administered both the shorter and the higher wavelengths, the efficiency of the photosystems was improved and resulted in both these systems working in tandem. The final output was a higher yield.

(Source: Wikipedia – The Emerson Effect)
The full spectrum wideband LED light from the Electric Sky is designed for all stages of the growth cycle. Hence, there’s no need to traumatize the plants with switching spectrums or swapping bulbs between the vegetative and flower stages.

In the graph below, you can see the wideband spectrum of the ES 300. 

Electric Sky ES 300 V3

As is evident, wavelengths of both lesser and greater than 680 nm are produced which results in the best growth.

              * If standard white LEDs were used, the Umol/J would read 2.2. Wideband diodes create near red and infrared light above 680nm, critical nutrients to plant growth, at a slightly lower “electrical efficiency”, but greater overall “plant efficiency”.

              The Science Behind Why the Electric Sky es300 is the Best LED Grow Light

              The Green Sunshine Company Electric Sky V2 wideband led grow light is 20% more luminous than other grow lights even when using the same wattage of 300 W. One could say that it’s literally brilliant.

              With its amazing spectrum projection coupled with its even light distribution, the ES300 simulates the sun’s magnificence more than any other full-spectrum light.

              This is interesting because the Electric Sky can provide better results than an HID system even though it has 40% less power and generates 50% less heat. That means the ES300 packs 500 watts of HID growing power into a more efficient system.

              So How Does the Electric Sky ES300 Light Manage to Do This?

              The answer lies in a few genius pieces of tech. Namely:

              1. TRUE 330 W wattage. This is important because most lights don’t actually give you the full advertised wattage. More on this in a bit!
              2. The patent-pending GS1 spectrum wideband LED lights. More on this right below!
              3. The linear lenses which provide two types of lighting – downward lighting, in a way that directs all that precious light to the plants and NOT other places; and more importantly, cross pattern lighting, for canopy penetration AND to allow for maximum growth without burning due the softening of the light.
              4. All the rest of the tech: the rectangular form factor which maximizes the grow area, the full-body heatsink for passive cooling which is super efficient, and the flexible dimmer with an amazing dynamic range giving you the customizability you crave.

              So, numbers 3 and 4, are relatively self-explanatory. These are smart decisions by a smart company that understands growing the way only growers can: better lights for better growing, additional effectual tech to complement it all; it all just fits and makes total sense.

              So, onto numbers 1 and 2.

              TRUE Wattage

              In your research as a grower, you’ll find that some LED lights advertise a peculiarly massive wattage output in comparison to what their actual power rating is. In some cases, if you snoop around more, you’ll find the truth listed under something called “true wattage output”.

              The fact that this is hidden is extremely disingenuous – essentially trying to trick you into buying a product that cannot do what it claims to do.

              In fact, apart from the duplicity, you’ll find that a number of these cheap LED lights are less efficient watt-for-watt than conventional bulb lighting, and may even underperform when compared to them.

              Which is why, just by providing a TRUE 330 watts, the Electric Sky 300 v3 wideband led grow light outperforms all the LED grow lights out there.

              Why a Wideband Color Output is Better for Plant Growth

              LED lights save energy. Everyone knows that. But LED lights can also provide a spectrum for excellent plant growth.

              There exists a custom of using LED grow lights that are just “white” or “purple”. Also, other “full-spectrum” LEDs are not what they say they are. Essential colors are left out, or in an attempt to utilize the least power on paper, the spectrum isn’t full. It’s partial at best.

              But here’s the kicker: plants can sense this.

              Plants are sensitive to a wide range of colors in their environment and they genuinely need this to grow well.

              The Electric Sky es300’s patent-pending GS1 wideband spectrum duplicates some of the Sun’s infrared wavelengths helping plants grow better. A balanced color ratio also guides plants into growing in a particular shape that yields maximum results.

              This special color ratio stimulates photosystems 1 and 2, increasing leaf sizes and thus developing extremely fast vegetative growth rates with high flowering yields. The kind of wideband spectrum used in the ES300 is more efficient for plant growth per photon than white LEDs. In fact, some studies suggest up to 25% greater yield due to the activation of the plant’s photosystems.

              The Emerson Effect:

              This distinct high-dosage of near-infrared light helps plants make more effective use of the light available to it, and hence grow faster and better. This effect is known as the Emerson Effect.

              Robert Emerson, in his 1957 paper, observed that:

              1. When plants are shown light with a wavelength greater than 680 nm, only one photosystem is activated.
              2. When plants are exposed to light with a wavelength lesser than 680 nm, the photosynthesis rate was reduced significantly.
              3. But when plants are administered both the shorter and the higher wavelengths, the efficiency of the photosystems was improved and resulted in both these systems working in tandem. The final output was a higher yield.

              (Source: Wikipedia – The Emerson Effect)
              The full spectrum wideband LED light from the Electric Sky is designed for all stages of the growth cycle. Hence, there’s no need to traumatize the plants with switching spectrums or swapping bulbs between the vegetative and flower stages.

              The Electric Sky es300 (ES300) Wideband Spectrum

              In the graph below, you can see the wideband spectrum of the ES 300. 

              Electric Sky ES 300 V3

              As is evident, wavelengths of both lesser and greater than 680 nm are produced which results in the best growth.

                The Electric Sky es300 (ES300) Setup Tips

                • Always remove your plants before setting up the lights and place the lights on the floor
                • After placing the lights on the floor, hook up ratchets or wire hangers and raise the lights
                • Ensure the air exhaust is at the top of the tent
                • An extra clip fan for direct airflow is recommended for maximum lifetime and performance
                • Always start the Electric Sky at least 3-4 feet away from your plants
                • For mature plants, lower by 1-3 inches each day until 18” away for flower, 24” away for veg

                          Customer questions & answers

                          Ask a Question
                          • Can I look directly at the LEDs?

                            Looking into the unit can cause serious eye damage. It is recommended that you wear eye protection when working under the Electric Sky. It is recommended to orient the long (metal) side of the unit towards where you or any other growers will access the plants most often. This will prevent as much light as possible from shining into your eyes because of the linear lenses. 

                          • Can I get my Electric Sky wet?

                            We do not recommend getting the Electric Sky wet. If your unit comes into contact with water, disconnect the power immediately and let the unit completely dry before turning back on.

                          • Will my Electric Sky get hot to the touch?

                            This depends on the airflow around the unit. In environments and open areas with plenty of air movement, the heatsink of the unit will feel barely warm to the touch. In grow tent enclosures with little air movement, the heatsink of the unit may feel very hot to the touch, but will operate at a safe temperature for the LEDs and electronics. ATTENTION GROW TENT USERS: In grow tent environments, it is recommended to operate a clip fan above the LED units for air movement. Always have the carbon filter or exhaust fans pulling air out of the top the grow tent with a fan speed controller. Low speed is usually sufficient for a recommended air temperature of 78-82° F.

                          • Can I get my Electric Sky wet?

                            We do not recommend getting the Electric Sky wet.

                          • How do I clean my Electric Sky?

                            The LEDs are protected by the lenses on the underside of the unit.  Use a microfiber cloth to clean the lenses on the underside of the unit. Compressed air is the best way to remove debris from the upper side of the heatsink.

                          • Can I plug the Electric Sky into 120V or 240V power sources? International plugs?

                            Yes, using the supplied adapters, the Electric Sky will automatically operate from a voltage range of 100V – 277V. The plug on the Electric Sky is a standard C13 plug found on many appliances. A standard power cord will plug into the Electric Sky.

                          • What is the maximum recommended ambient air temperature?

                            For still air installations with little airflow (such as a grow tent or mounted very close to the ceiling), a maximum air temperature of 85°F is recommended.  In large commercial rooms or situations with plenty of airflow, maximum air temp can get up to 90°F.  The ideal temperature for the best growth is 78-82°F.  

                          • How much heat does the Electric Sky put out?

                            The Electric Sky puts out on average, 50% less heat than HPS systems, especially because the light itself does not heat up your plants.  A small amount of airflow will keep it cool because the entire light is made out of a heatsink.  In most grow situations, a 4 inch exhaust fan is all that is needed to cool up to 2 Electric Sky units in a grow tent

                          • What is the recommended hanging distance for the Electric Sky?

                            For clones, seedlings, or plants just moved under the Electric Sky, the recommended hanging height is 36-48”.  During vegetative growth, the Electric Sky can get as close as to 18-20 inches away at full power, and closer with the dimmable functionality.  In flower, the optimal hang height is 12-18 inches, but plants can get as close to 6 inches away without burning as long as they are healthy.  The combination of hang height and intensity control allows you illuminate your plants in almost any configuration.

                          • What does a wideband spectrum mean?

                            The wideband spectrum means that the Electric Sky uses special diodes that output multiple colors at once, rather than just one color each.  They are designed to output a balanced spectrum tuned just for your plants, with a color output that creates a significant amount of energy in the near-infrared range (680-740nm) that helps the plant make more efficient use of light for a satisfying growth response

                          • Does the Electric Sky work for veg and flower?

                            Yes, the Electric Sky’s spectrum is specifically designed for rapid growth from seed to flower.  In veg, plants will respond quickly and exhibit tight inter-nodal spacing. In flower, flowers will be dense and flavorful, with production from the top to the bottom of the plant

                          Ultimate Winner

                          -The ability to raise temps in the room higher because of lack of infrared heat
                          -Completely even PAR
                          -Lowest lifetime cost of ownership
                          -Fast and helpful email responses
                          -Lower power consumption

                          Great Purchase

                          Been useing the es300 for about 3 weeks now and so far it’s looking on point, can’t wait to see the end results these things produce, had the mars reflector series prior and had issues, mostly cause I couldn’t see true colours there for not being able to pick up deficiencies had.. but with the es300 everything is true colour which is so much more practical and better for myself they have been so lush it’s amazing, with the results Iv had so far of three weeks I couldn’t help myself so I purchased another and waiting for it to be delivered..
                          And customer service by dan is so prompt it’s almost unheard of these days, keep up the great work guys hope to get more in the future

                          My plants love the light spectrum

                          I bought an es300 a couple months ago and I am defiantly going to buy two more. My plants love the light spectrum. Even on the lowest power the plants respond. The customer service is amazing as well. Returned my calls very quickly and answer all my questions completely. I highly recommend this light for any type of indoor grow.

                          Nothing less than AMAZING!

                          Nothing less than AMAZING! I’m using two of the ES300’s in my 4×4 tent. I’m 100% satisfied with these lights, not only with the end result which doubled my yield, but the quality of these lights. The housing alone for the lights are amazingly built, there were no corners cut when designing them. When sent to you, they even set you up for different options of hanging these lights. They were also packaged very well for shipping to prevent any damage from the currier. I do plan to be a returning customer, maybe I’ll pick up the 180 for my 2×4 that I clone in. I would recommend these lights to anyone and everyone!

                          This light by far is the best grow light I have ever owned. The lightweight design matched with top of the line parts is matched by no company bar none. I recommend this light to everyone I meet

                          Best light ever

                          This ohhh man it is the best light . Kind of price but the quality speaks for itself. Extremely bright but it has a white light appearance that I love. I was expecting it to run hotter but it actually runs cooler that I thought. Testing it out In my 2x4 tent lol

                          Pretty incredible lights

                          I’ve finished three small autoflowering crops with two of these lights now, and they’re pretty great. Plants thrive under these and produce viable buds all over, even when bud sites are covered by thick canopies of leaves. Plants grow with very short internodal spacing during vegetative stage, though the spacing expands during the flowering stretch as normal. The second go around with it managed to pull almost eleven oz. of dried flower from two plants, which was a clear record for me (still pretty new to it all, though). And it’s comforting to know that you’ve already got the best light for your plants (supposedly), so you can focus on improving other areas of the grow with confidence. But having said that, I’m still considering adding one more to my space to make sure that the center girls are getting as much as possible. I haven’t tried other led lights to give a proper comparison, but these blow my 400 watt hps lights out of the water in just about every way.. except maybe price, the only con to this product.
                          Oh, and one of my two lights arrived with the wrong cord, but they corrected it with little hassle in an acceptably timely manner. Hats off to you guys so far
