CEL: cool efficient lighting
by: RTG Design
CEL delivers a constant source of the specific wavelengths of light needed for plant growth. We have designed CEL to produce directional Photosynthetically Active Radiation (PAR) energy while dissipating heat through the reflector.
Plants use red and blue light for photosynthesis. Human eyes are most sensitive to green light. When sunlight hits a leaf; the red and blue light is absorbed by the leave to produce energy and the green light is reflected away. This makes the leaf appear green. We can make a very efficient and cool grow light by only producing the colors of light the plant needs.
Photosynthesis is the process a plant uses to make energy from water, carbon dioxide and light. CEL grow lights provide a constant source of the light needed for photosynthesis. Other types of LED grow lights use pulse width modulation (PWM) to drive the LED emitter. This flashes the LED faster than the human eye can see which makes the LED appear brighter. However, we have shown much better results by providing smooth and constant illumination through our special direct drive system.
