I have a few of these. I didn't use them long because they were nowhere near as bright as my citizens at the same watt but I'd say they're good for cheap supplemental lighting. Probably be great for veg.
Thanks I sure hope I do too!!! Sorry to hear they've done so badly for you. Can you please tell me in what way they died? Did they just flat out stop working, burn up, develop dark spots, or what? What voltage and frequency is your AC? Do you have any idea what temperatures they were running at?
