Adding T5 lighting

Pros: Complete kit, easy installation. Good wiring.

Cons: No control for individual lamps

I wanted to add the 2x39w T5 kit to supplement my Current USA LED. The kit is complete for sure and simple to assemble. I can't say how the additional light is working for the corals as it has only been running 3 days but overall I think this is a good product to add to an LED system. I do wish I had individual control of each light but knew that was not possible when I selected it.

Works OK, but Insufficient Instructions and Missing Screws

Bought this unit as a burn-in station for my 36" Dimmable fixture. Wish they sold a cheaper version without reflectors.

1) Well packaged. Encaps were loose in box, but were fine.
2) Supplied wires are very long.
3) Splash resistant endcaps.
4) Operates well.
5) Not hard to install/wire once steps are understood.

1) Ballast runs rather warm (almost hot).
2) Clip-On reflectors are slightly flimsy.
3) Instructions need photos to identify parts and to illustrate assembly and wiring. LET Lighting should spend one afternoon to take 6-8 photos to improve their instructions.
4) Instructions mention a website video for assembly, but it was not there.I did find a youtube video by a customer that was helpful.
5) Missing one screw for the mounting plates, and missing two screws for mounting the ballast.
6) Replacing bulbs is slower than typical fixtures due to threaded endcap design.
