Ordered 30W version. Have ordered these before and, like all the others, this one checks out 100%.
Ordered 1 before and was very impressed and ordered more this time. Much better than any fluorescent BLB bulb I've ever had.
Ordered 30W LED and very happy with it. Much better than the fluorescent BL tube I was using and plan to buy another.
Used this for curing UVA glue, puts out plenty of light just make sure its kept as cool as possible to avoid rapid degredation(30 Deg C ideally)
