MASTER GreenPower 600W HPS
Grow Lights600W
The MASTER GreenPower 600W is Philips' horticultural HPS lamp, catalogued as MASTER GreenPower 600W 400V E40 1SL/12 under order code 928159209227. It draws 602.5 W at a rated voltage of 190 V and Philips rates it at 142 lm/W — 2000 K, CRI 30, in a clear T46 bulb on an E40 cap with a 102 mm arc.
The 400V in the name is the ballast side of it: this is the high-voltage greenhouse line, not a lamp you drop into a hobby ballast. It is dimmable, burns in any position, and weighs 0.179 kg.
Life to 50% failures is 20,000 hour(s) and Philips put the running cost at 663 kWh per 1000 h. Between those two figures you can price a season before you buy the lamp, which is most of why the spec sheet exists.
