Was glad to see this review come up and corroborate the positive things I've read about this fixture. I've been planning to get 1 or 2 of the HLG 100 to replace, or at least get called into action before, my 250w HPS's, but waiting first to see if one happens to show up for xmas - maybe I should have left Santa a plate of poppers last year to to improve my odds.
Been thinking more the 4000K spectrum vs 3000K though, for tighter node spacing. I rarely grow for volume indoors, so compact growth is more important to me than potentially greater production. Everything I've seen of these HLG's (65/100/135) has been positive and I think 2 fixtures in a 4x2 tent would get the job done well, while drawing only 200w and generating minimal heat.
