Sunblaze TH50 light experiences?

Has anyone used these?

I am building a rack of tanks, and was thinking these might be a good lighting solution. I would probably start out with one, but I could very easily add another 1 or 2 for planted tanks.

They were used at a place I used to work, after 6 months 15-20% of them stopped working and had to be replaced
