    When I do use grow lights, I am partial to compact fluorescents over the standard tubes -- those in the 640K full-spectrum / 125 watt range. They color up Cephalotus and Heliamphora nicely, run on the cool side, and are, as their name implies, compact . . .

    But it does seem like you have enough light on hand to add some color to your evil vegetation. My only concern would be in parboiling the plants . . .

    The rule of thumb is for artificial lighting to be ~4-6" above the plants. That's how many centimeters? 2.54 times 39.36 minus 32 times 9/5......

    Since I'm not sophisticated with lighting, other than the general rule of thumb, someone else should answer about LED's. I just keep my lights a few inches above the plants and see how they respond.

    With lighting the closer the better! The reasen most people want to keep the light 4-6" from the plants is so they don't burn them. So the distance with any type of lighting really depends on how hot your light fixture runs. LED's tend to run on the cool side just like fluorescents so I would experiment with how hot they run and adjust if needed. But yes the general rule of thumb is 4-6". Also with lighting the farther away the plants are from the light the less lumens the plant receives. Light degrads over distance exponentially. Meaning 0-6" from light you get close to the light bulb output. 6-12" you get half. 12-24" you get half again. This will differ with different lights and fixtures but is a close enough discription for you to get the idea.
