Philips spent years developing a perfect horticulture lamp line with superior color quality. Their goal was to create the closest spectrum to the sun; crisp, white light. These lamps have a very high 1.95 PPF per second light source. The 3100°K or 4200°K color temperature models have a high 92cri, 33,000 initial lumens (105Lm/W).
