I am currently running two of these lights in a Budbox grow tent (0.75x0.75x1.6m size) - picture below!
I think the results speak for themselves. Currently both of my plants are looking exceptionally happy
In terms of features, both lights have an adjustable dimmer (one of the lights dims to off, whilst the other is a dimmer that does not turn the light off - although this is not a problem as both lights are on timers anyway).
I also like the nice long power cable that comes supplied (3m)
I've found running two of the lights independently in the tent to be beneficial - I've been able to tweak the intensity of both to suit each of the two plants in there (to a degree). I'm not sure of the impact but it makes me feel like I'm doing something for my girls!
I previously used a single one of these lights in a 0.6x0.6x0.9m GreenQube tent for my first grow. For the later part of the grow, I had the light on the dimmest setting because the tent was CRAMMED, and the plant was pretty much touching the light - nonetheless, the plant gave a 68g yield!
My single (TINY) gripe with the lights are the little hook things that clip into holes at the corners of the light. They frustrate me no end! I find it difficult to get them into the correct position/take them on and off, and once in place they sometimes force the light to spin into a random position when hanging. I think a swivel hook in place of these would be much more beneficial (although I recognize I could buy some separately!)
However, overall - exceptionally pleased. Excellent build quality. Much love to IS!
