Two switches: one that turns on the COB, which emits a “full spectrum” light that is containing all the visible light bands and another that turns on the LED ring placed around the COB, which emits only the radiation most used by plants in both vegetative and flowering phases.

This line has a peculiarity: 60 ° lenses mounted on the COB LEDs that concentrate the emission beam in an optimal way for the cultivation of medium and large plants. If you are used to using HPS lamps this line is the one that comes closest to your habits

But be careful!
The lenses can be removed.

Using hight quality COBs and 3 watts OSRAM Oslon LEDs We have obtained a line of highly performing lamps

You can widen the emission angle from 60° to 120°. In this way you will also adapt your lamp to crops of low plants, cuttings, sea of ​​green, SCROG and all cultivation techniques aimed at maintaining the small size.

in the first 2/3 weeks you can only use the outer ring, in the vegetative phase you can only use the COB, if you want to limit consumption, or turn them on both, if you want the maximum mass. During flowering it is necessary to always light them both. During flowering, both must always be switched on.
