Hanging T5 lights from...
 

Does anyone know how much one of those 4 or 6 bulb T5 lights weigh? I have (3) 4ft jump start grow light set ups that came with a single bulb. I want to use the rack or hanger or stand (what ever it's called) to hang a 4 or 5 tube fixture from it. :roll: :hmm

Here is the weight of a Hydrofarm 6 Bulb fixture with bulbs (24lbs).

Others are likely to be fairly similar.
