Not even the size of a t5, let alone t8. Only about 6 inches per light. The aluminum panels are not adjustable at all.

Oftentimes, it's not about the product that’s being sold but how well companies stand behind their products. Owning these lights can be a challenge. Produces a solid plant with the light spectrum the light uses.

This light is just as bright if not brighter than my hps light that i was using. Purchased this to upgrade the lighting in our nursery. Please note though, they advertise samsung 301 led's and they send a light with lm281b+pro led's.

Extremely unhelpful. Best you can expect is a light that (might) be ok for one plant in vegetative. Ended up messing up my grow as if the nutrients being wasted are cheap.

This is not 2000w, this is 200w. The fixture is very weak and has a 2'x2' coverage footprint at best. The light casing gets hot. This light advertises less than 4000 lumens and says its like having a 1000 watt light, thats impossible.
