The Citizen brand CoB (chip on board) LED grow light with a color temperature of 4000k and a CRI (color rendering index) of 97 offers a wide range of reds and deep reds and improved blues compared to its 2700k and 3000k CRI 97 counterparts. Because it allocates a significant portion of its power to blue photons and maintains a highly saturated red zone, it serves for all stages of cultivation. This CoB can be interpreted as a full spectrum light but with more greens, which will not harm your plants, as any unused greens will simply be reflected back into the environment. Due to its more favorable thermal resistance than full spectrum lights, it offers a higher amount of moles per second and square meter. Its power range is from 36.7 watts to 117.6 watts.
