ELB Electronics LED T5H-48-32-850-FHF 10-Pack LED T5H-48-32-850-FHF, Plug and Play LED T5 HO, 4', 30W, 5000K (Daylight), DLC Qualified, Replacement for 54W T5 HO, White (Pack of 10)

Installed 10 of those in my shop. Installation was very easy and the lamps appear to be brighter than the old fluorescent lamps.Overall, I am very happy with my purchase and will buy more to replace remaining fluorescents.

I went from 4 54 watt florescent bulbs to three of these per fixture. Happy.

Total waste of money. I actually threw two cases of these away.
