Constantly replacing costly bulbs and reflectors is not an issue with a LED grow light. The high power LEDs from CREE have been tested to last 85,000 hours at over 90% output (that's almost 10 years!) and there is no need for a replacement reflector thanks to our unique optics.
LED grow lights emit far less infrared radiation than traditional grow lighting, which can reduce heat stress and damage. Also a tailored spectrum is easier to produce with LEDs ensuring your plants get the light they need.
