Rated 5 out of 5 by westmidtownsnap Great alternative for more expensive bulbs
We worked with our sales rep to determine if there was an alternative bulb to the $50 ones we had been buying elsewhere. We found one that was lower wattage, brighter light and lower price - good things come in threes. I have recommended 1000bulbs.com to other business owners as I like the service we get.

Rated 5 out of 5 by RobbieG Great value
We had some arrive broken , need to pack better for shipping. As far as the bulb quality , very effective . We replaced 320 w metal halides in a carwash....very pleased and no more expensive ballast or bulbs.

Rated 5 out of 5 by IBWashincars Great for replacing metal halide.
I have four car washes that all had 175W metal halide fixtures, many in need of repair. Instead of replacing expensive ballasts and bulbs, I decided to try these 105W CFLs in one wash. I was so pleased with the results I converted my other three washes within the next couple of months. These bulbs are just as bright as the MH and the light is whiter. The conversion was as simple as throwing away all the guts from the light and run the 120V right to the socket. Now I don't have to deal with the ballast/transformer and the problems with the associated heat they generate. I'm also saving 70 watts on every fixture. 17 months later, I have still not had one burn out. This has been one of the best upgrades I have done. I have nothing but praise for this product.
