CFLs put out a good deal of heat. they actually put out more heat than HIDs.

2. No fans built-in or required.

3. Light spectrum designed specifically for plant growth.

4. Extremely long life. Only 35% lumen loss after 100,000 hours. Twice that of LEDs.

CFLs need to be replaced every six months at least as they wear out easily. HID bulbs also need to be replaced about the same i believe.

LEDs should theoretically never burn out, but they loose light output after 50,000 hours or so.

5. Five year guarantee. Repairs after that time are not to exceed 50% of the price paid.

6. No supplemental light required. Designed for both vegetative and flowering dues to strong output at blue and red; yet all of the lesser frequencies are covered.

this will have to be determined.
