Given the minimum heat emission these lamps can be placed at 5-10 cm from the plant, do not dry the substrate or cause temperature rise in the cultivation room. CFLs offer a viable alternative to incandescent lamps especially in the vegetative phase, have a greater average life and are easier to use, as they have the built-in ignition system: connect directly to the reflector via E40 attack, just attach the plug to a power outlet and is ready to use.

VANTAGGI: little heat, reduced encumbrance, multiple uses.
