                      Ask a Question
                      • Would this light do well flowering a 5×5 area?

                        Yes, its about 4’ x 4’ large and can cover up to a 5’ x 5’ flowering area!

                      • What does the EXT on the round switch do?

                        The EXT switch is where you would run the light if you were using the master controller with it.

                      • What’s the actual wattage ?

                        The wattage can be changed with the power switch. 680 w at 100% and you can select down to 40%. It also has a more than 100% setting but I only see that it is brighter than the 100% setting. Use a light meter to set the distance and power level.

                      Roi e680s

                      Sturdier construction, better places to hang light from on new design, has a twist knob on each end to hold light in open position, it’ll take a few weeks to see how the plants like it, so far I’m happy with new build.
