Not quite what I expected
I read a lot about these lamps, but I was a bit disappointed when I got them. The light quality wasn't as good as I hoped. They work fine, but they were supposed to be brighter.

Good value for the brightness
Overall, these Jesco lamps are a great value for the brightness they provide. I use them in my garage for woodworking, and they illuminate the space really well. Only downside is they flickered a bit at first, but they settled after a few hours.

Decent but arrived late
The Jesco T5 lamps work well and provide good light, but I had to wait longer than expected for delivery. A bit frustrating, but now that they’re installed, I’m happy with their performance.
