Using an XS2000 and it’s the perfect temperature as well.I've been checking out the new Viparspectra xs150 pro lights used in this grow. Now granted they are only at 50% of full strength I'm finding them to be comfortable to the touch. I mean I can grab and hold onto the driver.
I will at some point measure the light intensity at various spots in the tent to see if the lenses do disburse the light as advertised which would be a real positive.
So far I'm happy with what I'm seeing with the xs 150 pro lights.
Probably my only complaint would be that the dimmer is only like 5 positions instead of just fully adjusting. Sometimes I don’t need 100% but I need just a little less and it takes you to 80%. Just means using the meter a tiny bit more, something I should do anyway.
