Needs reflector!

Mark already asks for this in his comment. I agree a snap on reflector to hide the light tube would be really great. I'll improvise something but you can make something to fit perfectly. BTW: the magnets are very strong and make a secure mount - thanks!

Great easy to use light!

These lights are super bright and so easy to use. Used them in a basement and a shop for quick quality lighting.

Reflector accessory would be nice

I like the lights, but there should be a reflector accessory. I'm setting them on top of bookshelves for indirect lighting, but the light goes sideways as well as up, so it's in your face without some kind of reflector.

Great for viewing inkjet prints

I bought these to view my inkjet prints for more color accuracy. I like the fact that they are 95 CRI and a high CRI R9. Easy installation and the fact you can daisy chain multiple units together. plan on buying more for other location.

magnetic mounts are great

The included magnetic mounts are really handy. I'm don't have a means of confirmation but it does appear to be a proper 5k color temp next to other lights.

My complaints are that the units are much shorter than 2' (check the spec sheet) and that the c7/c8 connection between units is fairly loose.
