Rated 5 out of 5 by Fantastic product We use these in over 70 post top side walk fixtures. My fixtures are not maintenance friendly at all! My sales person at persuaded my as to the quality of construction. She was correct after one year NO REPLACEMENTS! They work better than GE, Philips and Sylvania for less cost! July 13, 2011
Rated 5 out of 5 by Very Good Value. For the 400 Watt Metal Halide lamps it seems the smaller, the more they cost. Paying Locally $33-45 For the lamps, the smaller ones being The $45. Purchased 4 lamps from 1000 Bulbs at less than the cost of one. Installed for over 8 weeks no issues at all. Fit great in the current fixtures. great way to save money, no decrease in light noted at all. June 7, 2011
