Hi I wondered what you thought about this interview? I was looking to buy some high CRI LED panels but it looks like that's no guarantee of quality what do you think?

High CRI lights are always better than low CRI.

Also you must take into account that spectrum measurements just few years ago was only used by few guys and some manufacturers. Now it is quite different.

Source spectrum measurement contains more info than any of measurements converting this into one number. And how to convert it can be debated.

Interesting. Here's the score list the guy is talking about.

And here's the other page which tells you how to interpret those scores. The higher the number the better. There are a lot of expensive lights there which are ve fairly low scores for the price. http://www.gtc.org.uk/tlci-results.aspx

Great info! I knew there was something I liked about tungsten light (lol). This is very eye opening.

Howdy, Stranger!
