I have HLG 100, HLG 135, and HLG 288 QB’s. One of each. All Rspec. What size space do you guys think is possible to light with these?

Are you planning on vegging and flowering with these lights?

Between the HLG 100 and HLG 135 You should be able to get decent coverage if you keep your flowering footprint to 6 to 8 square feet (closer to the higher number if the walls around your space have high reflectivity).

As far as the "HLG 288 QB's" , that is the board used for the HLG 135. Do you have a driver for it, and if so, which model?

I actually just bought the 288 yesterday online so I haven’t gotten it yet and I do still have to buy a meanwell to put on top. Are you telling me it’s the same as my 135? Sorry I don’t understand :wall:

And I would veg and flower underneath, it hasn’t seemed to be an issue thus far.

HLG has some really good YouTube videos showing different configs and lighting power.
e.g. I have a 4x4 tent with two reservoirs and 6 plants in week 2 of flower. I have 3 288 V2RSpec board; DIY kit inbound and a HLG-320H-C1750A driver. In flower this will cover my plants at 30" above the canopy and pretty much blow every other system away.
Here is one showing the light saturation:

Yes it's the same if the HLG 135 you have is a V2 R-Spec model (HLG currently offers the DIY kits with R-Spec Or B-Spec boards and there are older versions still in use). What driver does your HLG 135 have, a Mean Well HLG-120H-54A? If you get the same driver for your new board, it will cover the same area. About 4 square feet or 10 to 12 square feet between all 3 of your lights.
