led lights

The two most important criteria for full spectrum lighting are the CRI (color rendering index), and the color temperature rating, measured in Kelvin degrees. The CRI rating goes from 1 to 100, the closer to 100, the more true the colors. A Kelvin rating of 5000 or higher produces more lumens (light registered by the rods of the human eye) and controls pupil size. Noon sunlight is generally around 5600 Kelvin, and 5000 Kelvin or higher light gives the appearance of substantially more light.

Halogen bulbs ~ 3200 K and 100 CRI

LED lights ~ 6000 K (posted by RedDevil) and 70 to 90+ CRI
As the lights posted by RedDevil are 6000 K, I would imagine their CRI is close to 100 as well.
I've been using LED lights in my home for years, used full spectrum before that, and the LED lights are better.
