Customer Reviews

Rated 4.7 out of 5 by 3 reviewers.
Rated 5 out of 5 by Great Retrofit Product This product is great for retrofitting MH and HPS under canopy and wall pack lighting! April 5, 2012
Rated 4 out of 5 by Quite bright, only a little cool to my eyes Fast starting, very bright, not exactly a small energy footprint at 42W but understandable considering its size and brightness. Silent, flickerless. Color seems fairly true, good enough for our clothes closet and laundry room anyway. March 22, 2012
Rated 5 out of 5 by Incredible light output! We use this lamp in open exterior fixtures . They are a full spectrum lamp that brightens our exterior tremendously, enhancing our "curb appeal" and raising the perception of safety and security during the night hours. The price is quite competitive and allows for a quicker payback time verses using an energy wasting incandescent bulb. As a bonus, you cannot go wrong with this supplier. October 28, 2011
