I very rarely ever write reviews but this product is so bad, I felt I needed to in order to potentially save others from making the same mistake.
I bought 12 of these fixtures over the past 3 months for some lighting projects INSIDE my home. I thought it important to note that these are being used in my office, in a climate controlled environment and have no outside sources working against them. Temperature has been maintained between 68F and 74F. The lights are being used as grow lights for my seedlings, which were all bottom watered (no moisture issues) and the lights were set on a time, 12 hours on and 12 hours off.
There is positively no reason these fixtures should die in less than 3 months (some are barely 2 months old). Out of the 12 I bought, only 3 remain working and one is starting to flicker today so I assume the ballast will be blown on it by the end of day.
These are an absolutely horrible purchase if you actually plan on using them.
