MASTER GreenPower CG T 600W HPS
Grow Lights600W
The MASTER GreenPower CG T 600W is the largest lamp in Philips' CG T horticultural HPS line, order code 928158809214. It draws 618.0 W at a nominal 130 V and Philips rate it at 142.4 lm/W — the highest efficacy figure in the family — at 2000 K with a CRI of 26.
The bulb is a clear T46 on an E40 cap with a long 151 mm arc, which is what a reflector is shaped around; a fixture built for a shorter lamp will not focus this one properly.
Rated 32,000 hour(s) to 50% failures at 680 kWh per 1000 h, dimmable, and it burns in any position. CRI 26 is the lowest in the range — irrelevant to the plants, relevant to you when you are trying to spot a deficiency.
