I bet they are 277v input voltage and you will not be able to use them.
Zandor Reviewed by Zandor on . Lighting Question Well im getting 3 free 400 watt hps lights because they were stolen and my friend can't hold any hot items in his house anymore... So i was wondering, why do people use weak lights during veg, then stronger lights during flowering?.. Is that a must?.. Can i just use a HPS for the whole grow?... Thanks.. :thumbsup: Rating: 5
