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 5 out of 5 by 1 reviewer.
Rated 5 out of 5 by 5 years later and these things will still blind you! 400w probe start metal halide doesn't stand a chance - it's been 5 years and these run 24/7 on pulse start ballasts and the warehouse is still much brighter than it was with the probe starts before, heck, not even one has burned out yet, and if you look into the fixture one of these things even today, it will still blind you!
