I believe the numbers I posted above are for greenhouse use, because you do have the Sun Light Factor. Even a cloudy day has a lot of lumens. Not sure how many without looking it up, but I know its fairly high.


The Green House in question is 24x24. Sidewalls about 6 foot tall. Center peak is about 12 foot. Im thinking the heat from the lights would benefit the environment overall.


I guess I didnt word my question quite right. What I meant, does the heat hurt the light if you dont vent it? As in, you must vent it, because it might cause long term harm to the light?
