How is OttLite different from other lighting?
The OttLite ClearSun LED technology is our exclusive LED that is as close to the spectral output of the sun as you can get! That means reduced eyestrain, a balanced natural illumination and incredible color rendering. Most LED lighting contains a high concentration of blue wavelengths which is known to cause eyestrain. Our one-of-a-kind ClearSun LED provides smooth, clear illumination for hours of visual comfort.

What is the CRI (Color Rendering Index) of your OttLite ClearSun LED?
Our CRI is 95+ which means the OttLite illumination shows colors with incredible accuracy, just like the sun. Most LED lights are in the low 80s.

How many lumens does this lamp offer?
450 lumens at the highest brightness level. The lamp features a touch switch with three brightness settings so you can adjust based on what works best for you.

Tell me more about the color changing base.
With the fun color-changing base feature you can choose one color or cycle continuously through the entire color spectrum.

How long has OttLite been in business?
OttLite was founded in 1989 by Dr. John Nash Ott. Dr. Ott was a photobiologist who spent over 40 years researching natural daylight and its affects on all living things. Today, we continue Dr. Ott's incredible work finding new and innovative ways of bringing the power of natural daylight indoors.
