The Philips Energy Advantage CDM lamps with AllStart Technology are a high-efficiency protected 'O' rated CDM lighting solution that provide energy savings without compromising light quality. They offer the cost saving convenience of being usable with either Probe or Pulse Start magnetic ballasts, ANSI M59/O, M128/O, M135/O, M155/O, M165/O, M172/O, or C185/O. This 330 watt AllStart lamp provides a net savings $170.00 per lamp when used to replace a standard 400 Watt lamp equating to a simple payback (Investment Energy Savings) of 1 year.

Customer Reviews

Rated 4.5 out of 5 by 2 reviewers.
Rated 4 out of 5 by Very bright, full spectrum We recently changed a few of our bulbs as a test in one of our warehouses. Some of our workers were having trouble reading prints under our older bluish lights, but they all say that these bulbs make it much easier! On another front, 330 vs 400w may seem insignificant, but multiplied over many lights, the cost savings will certainly add up! May 6, 2013
Rated 5 out of 5 by The Best! I couldnt ask for better bulbs or service! 1000 bulbs is the best. May 3, 2012
