Of course you can still use them. I've seen no damage with 28-30" distance and up to 2h per day and only a bit with 24" and up to 4x 15 minutes the day. With less distance it's almost impossible to not cause damage with these bulbs unless you let it run for only a few minutes.couldnt you just use the agromax further away for a shorter amount of time ?
I've created wide wing reflectors and have made so called superspreaders to reduce the hotspots directly below the bulbs.. No chance! I've burned my girls their asses off and lost almost 20% yield.
My prefered hanging height is 12-14" and I need something I can use in this distance. The pureUV bulbs need twice as much distance and even then one has to be careful to not damage the plants.
So if thats no problem in groom you can still use them.
