Most Helpful Customer Reviews
Returned, they came marked as 400w but they were smaller than the existing bulbs and soooo much dimmer,
Not quit as bright as our old ones but for the money they will work
This product comes with 3 light bulbs. Each of these bulbs are 400 watts. When I got these there weren't that many reviews but one was not very promising of this product. When I got them I tested each to make sure they worked, and all 3 of them did (they were packaged good). I have one in use right now, and it's been 2 weeks and I have had no problem with the bulb. The bulb is nice and bright also. I received this product in exchange for my honest, unbiased opinion.
