When mh or hps lights are on a pole in the dead of winter. On a street corner they appear to work. Seen ice hang from them. Just try it i guess.
bobjob4u Reviewed by bobjob4u on . Light intake temp? Hi, guys some one was asking me if in the winter months when it gets to 30-0 deg. F. if his lights will be ok or will their be some thermal shock their? he vents his lights from outside air through the light then back out side again? he has never grown in the winter environment and I didn't know if there would be some glass breaking their? I didn't event think of it till he brought it up. I figure those lamps are at about 100F then the air from out side at 15F would that be a problem? how Rating: 5
