Quantum dots, or nano dots as they are also called, have been in the science press for years now, doing cool things like assisting in medical imaging and improving the efficiency of photovoltaic cells. Nano dots are now getting partnered up with blue LEDs to produce a broadband light emission from the notoriously narrow bandwidth LEDs we are currently using. The Quantum LED spotlight from Array Lighting is being touted as the highest color rendering LED lamp ever made with a CRI of 90.
The Array Quantum LED spotlight is eight watts of LED with a rated color temperature of 2700 Kelvin and a beam angle of 60 to 100 degrees. That 2700 kelvin rating sounds kind of low but since current white LEDs have a CRI in the 70s, that’s a lot of colors that they are not rendering. If the angle of the Quantum LED spotlight is wide enough it could be a great coloring addition to our overly frosty LED reefs. The Array Quantum LED spotlight is selling for about $110 at Green Lighting Supply and early adopters will basically be paying $50 for the priviledge of a nano dot lens as the same LED light sells for $60 without it.
