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.

Great lights for the garage

I'm planning on installing a bunch of these in my garage to light up the space. I bought a four pack to try them out. The light quality seems great. I like all the options for mounting and wiring them up. I'd be interested in different fixtures like these for use inside my house as well!

Very satisfied

I purchased this as an inspection light for work, but have to buy some more for home because it was so useful to draw under. It produces a very even, natural light without any flicker. I had received some run-of-the-mill LED under cabinet lights for free a few years back, and these units from Waveform are miles ahead in quality while still at the same price point. There are far too many lackluster LED lighting solutions out there, but this is arguably better than anything else you could buy. Even better than the high end fluorescent tubes. My only real complaint is the lack of option for a longer cord, but those are easy enough to find.

Makes a nice TV backlight!

This fixture makes a pretty nice 5000K high CRI backlight for a 60-70 inch TV. It reduces eye strain and improves perceived contrast compared to watching TV in the dark.
