I havent logged into this site in awhile but this post i had to reply to..
There is very close to no answers when comes to gravitas online or double ended bulbs . they are mostly from awhile ago before things were on the market everywhere. My point is, to say gravitas catch fire is not fair to say without real evidence. This post will come up when people google info for these things and it shouldnt mislead people.
I just purchased 16 gravitas, buddy did 7 gravitas, an older guy getting 2lb plant per light in 4×4 area with xtrasun bulbs and xtra sun hoods, just bought 48 gravitas, every person who works at grow store shows pictures of there room with 8-10 gravitas each. the dispensary local just bought 99 gravitas. The store has pallets of 600w gravitas empty every week. He tells people to buy 600s unless running very large cielings which most are not. The 1000s still go just not one at a time. Most people getting 1000s are like me doing commercial space an get many at once...
Also if you look online about the technology , its used in MANY stadiums and nasa uses same technology. I really highly doubt the fires your buddy speaks of were actually cause by lights. Instead odds are user error 99% time. After all its a light bulb and completely enclosed ballast.
So not saying your buddy is lying just that it is possible the growers who had fires didnt wanna hurt there egos an tell truth. On top of that, the head guy at he store said hes vert close with guys with gravita tech. And the other stores in my state have hard time stocking them. So possible the company supplying him is not willing to give him supply an hes choosing to sell what he able to stock.
Idk, att he end of day people will read this off google vased on thread title an dont want people to be misinformed.
Edit: Sucks for your friend who owns store cause no joke, this guy over here is selling PALLETS of these things weekly. So you are correct he is loosing major sales by refusing to stock them.
