I've been checking the quality of my light sources for years using a CD (florescent vs LED vs incandescent). Didn't DIY'ers know this technique for years?

- jonhohle 3y agoI’ve been wanting to check my lights and didn’t know about this. A few years ago we had several cans replaced with solid state LED fixtures and my wife has had a lot of trouble with sleep which roughly correlates. It may be placebo, but it seems like she also may get better sleep when watching an OLED TV vs an LCD iPad. It made me wonder if we should put 460nm filters on our ceiling lights.
- TacticalCoder 3y agoHow does that work? Are you using a CD to tell if one fluorescent bulb is better than another? Or to tell if one bulb is LED or incandescent or ...? > Didn't DIY'ers know this technique for years? I used to live in a rural area (fixing everything in the house by myself) so I'm quite the DIYer but I don't know anything about that!
- crazygringo 3y agoUsing a 0.2 mm slit? Or do you have an easier way that uses just the CD? First I've ever heard of it, and I went pretty deep into the rabbit hole of spectrum when I switched to LEDs in my home. Don't think this is very common knowledge.
