Our LEDGrowLight™ combines the gentleness of fluorescents with the growing power of HIDs. Our lights are warm to the touch and have a minimum useful lifetime of 50,000 hours- the equivalent of 18 hours a day for 71/2 years.
Some of our tests and graphs are with our 1st generation blue led and 2nd generation red led bulbs, unless noted. They have been improved and replaced with our current bulbs. (refer to products*store)
