Hope it Helps.

From http://www.fullspectrumsolutions.com/natural_lighting.htm

"Sunlight in its pure form has a kelvin temperature of around 5,000 degrees kelvin and a color rendering index of 100. As sunlight comes into contact with the earth's atmosphere and is reflected and refracted by water and dust particles the color temperature actually changes throughout the day ranging anywhere from 5,000 to 6,000 kelvin depending on the time of day and the amount of clouds in the sky. Artificial lighting sources within this range can appropriately be considered a natural lighting lamp as long as the color rendering index is above 90."

The problem is most artificial lighting has horribly terrible color rendering.. Often 80 or less..

You can find now days CFLs designed for studio and photography which often achieve 90 or better but they will also be 5000K-5500K..

LEDs, not so much as of yet for color rendering, hence LED specific filters..

I'm in the lighting fixture design and manufacturing business for high end applications in museums. About 75% of our business is now LED with 97 CRI without any filters or gels. The LED technology is getting better every day with some really great products coming on the market.

The KEY is "High End".. Most folks here are buying via SURPLUS/bargain basement odds and ends market often through Ebay.. Basically put, very spotty quality in life, color, lumens and CRI..

Even buying LED bulbs in retail stores is a hit or miss for quality and CRI..

It HAS improved price wise and quality but still no where near what it SHOULD be.. First LED bulbs I bought 5 yrs ago in a retail store cost me $19 for one outdoor flood light.. It lasted only two weeks before half the LEDs quit working and in one month NONE of the LEDs worked.. It was also half the advertised brightness, it wasn't as bright as the incadescent bulb that it was supposed to replace..

Just recently bought a phillips outdoor flood light, 14W draw and is supposed to replace a 75W incadescent.. I had a 14W CFL in that fixture.. The 14W LED turns out to be about the SAME brightness as the 14W CFL.. Basically a wash in brightness.. The 14W LED costs TWICE the price of the 14W CFL.. Lets hope it lasts longer than the CFL..

Very few people on this forum would be willing to pay the price for high end LEDs.. Most have a fit if they pay more than $2 per fixture in their RV.. So for on the cheap they CAN correct the color..
