Works great, love it!
Had trouble finding a replacement bulb and this one works great! Great brightness and good value for your money too considering the alternatives!

Good so far
Reviews always have me feeling some type of way. They range from excellent to do not buy. Took a chance with these since 2 are the price of 1 name brand bulb. So far they work and haven't had any issues.Only problem I had is with driver dropping package off. These packages should be labeled as fragile. The driver dropped the packages onto the ground instead of setting them down nicely. I get they are in a hurry but I feel if packaging was labeled as fragile the delivery driver would of taken the extra precautions to gently set the package down.

One of two bulbs failed immediately
We just got these bulbs in and installed, but one burned out within days of being used. Not sure how to do a return for just one. If the vendor can address this, I will change my rating.

Lights came intact, packaged well.
Product works as advertised. Got to wait and see how long they last.

Cooked my plants
This was my second order of these bulbs. The first 2 are still working great. The second order I installed both in the same 4x8 tent and the 4 plants under one side cooked and the 2 closest to that same bulb sustained bad burns. The lose was worth 10 times the cost of these cheap bulbs. Lesson learned I'll stick to quality from now on
