Need Recommendation On The WORST LED Lights Ever

[Manfred Lopez]

I was wondering if anyone could recommend me the model/brand of the worst LED lights you have ever come across. I'm trying to recreate the lighting test bellow to demonstrate the difference between high CRI and low CRI. I want to recreate a shot of a purple object that comes across as blue when lit with very poor lights. Any ideas?

If you buy a roll of LED tape form China and staple it to a white foamier board you will have a nice low CRI greenish LED light and won't cost you much for your test.

My fear is that some LED's from China are actually quite decent nowadays. That's why I was asking if anyone knew of a specific brand I could get. I unfortunately don't have a color light meter to test them at the store.

Neewer's on-camera LEDs are atrocious. If it's not bad enough, I suggest dimming them slightly and using a rolling shutter camera... so the flicker gives you rolling bands of sickly green light.

The other way to go is to use an RGB par, like they use for stagelights. Balance the RGB to 5600K by eye and then put anything with synthetic dyes under it. Since they are designed to be the opposite of good CRI, they are probably the perfect example. We rent them in the shop for like $12 a day or something. Just try a rental house that does AV and events and they should be able to help you out.

Thank you very much! This last part sounds like a great idea. I will try it out. I'll also follow Peter's suggestion of cheap Chinese LEDs against white foam board. Coming up with bad lighting is actually a lot of fun.

CRI is not a good measurement on quality when it comes to LEDs. In theory, TLCI-2012 should be much better, but the current modeled camera is a 3-chip prism based, so questions have been raised in how well TLCI-2012 applies to CMOS based cameras. Take a look at this list, the Lightpanels Sola 6 does poorly on it receiving a 46.

Did you ever get a sample video of this?

Buy some plus green gel and create your own low CRI light.
