The light I have in the tent is also a 100W but it's dimmable, I thought the new one would be the same but nopeI had a Giixer for a while (it was a blurple light) lol it did the job "ok" but not even close to the size of your nuggys reason I ask. I ran it wide open too. I'm kinda wanting to get some of these Barney seeds though. Every one I've seen has looked amazing
