Natural white light plant viewing mode

The plant viewing mode of Solarsystem 550 is simply amazing. It switches off the blue and red LEDs leaving the plants in a natural white light. It becomes a lot easier to identify possible nutrients issues, pests and diseases etc.

Its also nice to show your friends your plants under natural white light conditions – a big improvement over yellow HPS light or the typical pink glow of most LEDs. The ‘plant viewing mode’ is easy to switch use; Using the hand held controller, simply select ‘Manual’ and then click on ‘View’ and there it is – normal daylight spectrum which is a lot less strain on your eyes

Review of Main differences between LED and HPS Lights

  • LED produced more compact plants, less stretching than HPS – no elongated stems.
  • LED produced vigorous, healthy plants with beautiful dark green leaves – like most good LED’s.
  • Growing with LED produced much less heat than HPS. Its enough to keep the grow room warm without making it too hot. LED is therefore easier to work with in summer months, hot countries and smaller indoor grow tents, less air extraction is needed.
  • Herbs grown with LED need less water per day due to cooler grow temperatures and reduced transpiration. Plants are easier to look after, and its better for the environment.

Why we love 550 Solarsystem LED grow light?

Pair with the California Lightworks SolarSystem Lighting Controller

The SolarSystem Controller is what really makes the SolarSystem 550 so versatile, with the adjustable spectrum, programmable mode, manual mode, adjustable power and ‘white light’ plant view mode. If you are planning on growing plants that demand to toggle between different wavelengths of light in the spectrum with specific intensities during the growth stages, you are getting the right thing so far. Simply use its screen to vary the light intensity of three different light spectrums from zero to ninety-nine percent. The SolarSystem 550 also has IPX65 water spray resistance, and several units can daisy chained together and all controlled from a single controller.

More excitement— the California Lightworks SolarSystem 550 lights have the ability to mimic the sunset and sunrise with the aid of timer control. Moreover, to ensure that your plants flourish in the best possible ways, this LED grow light meet their demands of specific light characteristics in the fall, spring, summer and winter seasons.



 Using the touch screen system controller, you can adjust between three separate light spectrum channels, each from 0% to 99%. Channel 1 corresponds to red and deep red light. Channel 2 corresponds to natural white light, while Channel 3 corresponds to blue and deep blue light. Depending on the present state of your plants, you can adjust the light and spectrum control accordingly for optimal growth.

  • Automatic day/week/month customizable calendar programs
  • Wireless or hardwired networking
  • Control over an almost unlimited number of lights and zones
  • Battery back up saves the program if power is lost.
  • No proprietary cabling (simple phone cord will work)

  • Options are available for PC, wireless, internet, and smart phone applications



In settings where this LED grow light works together with the sunlight, the light sensor would be integrated with the controller to relay the intensity of sunlight. This way, the light fixture could be switched off if the sunlight is enough on its ownIn addition, the light fixture could also be connected to a smartphone or pc to export data into them.

Power capabilities and light footprint

The 550 lights only draws around 400 watts from the wall at full power making it a very efficient and economical light for both grow rooms and grow tents. That's a 40% power savings over traditional HPS lights.

The 6' x 8' veg and 4' x 4' bloom footprint make it an excellent choice for standard grow trays and frames as well. Weighing in at just 13 pounds, this light is very easy to adjust and hang.

To truly get the most out of this like you really do need to pair it with the controller. The controller screen is also fragile. So just like any other electronic device, be careful with it. Luckily the controller comes with a handy wall mount bracket to keep it from harms way.




What comes in the package?

The SolarSystem 550 comes in a combo of Method Seven Operator LED+ glasses, the controller, and two fastening ratchet ropes. Since the LED grow light could operate in a spectrum other than that in daylight, these Method Seven Operator LED+ glasses are specially designed to filter out the disturbing radiations; consequently, allowing a comfortable operation to the user.

If your plans encompass around gardening in a vast area with a variety of plants demanding unique working conditions from the LED grow lights, the controller comes in handy here. In fact, this single controller is efficient enough to control numerous LED grow lights.
