105w CFL

Anyone ever use 105w CFL bulbs?

These things are massive..lol.

Wanted to know how far off the plants your placing them?

Pic of both the 105w and 65w.

I keep my seedlings 4 in from my t12 floresants.

Place your hand inbetween the plant and bulb, if it burns raise the lamp.
If it doesn't burn your hand your good, usually 4" gap is ok.
The idea is too keep it as close as possible to avoid reaching but without burn.
