Hlg 550 vs hlg 600

Yea maybe for efficiency or life of the boards? I'm wondering why they don't use the 312 pcb instead of the 288 and 304s

Do you think lifespan will be affected and is this why hlg has a 3 year warranty on the 550 and a 1 year warranty on the 600?

I dont think lifespan is an issue with those type of LED.. they are good for at least 7-10yrs most likely probably more.. i wouldnt worry about that.. its just a bit less efficient but you still get more lumen output

Im sure there is a way to make it work using current mounting holes but id watch for heat as hlg550 wasnt design to run at that power.. not saying it wont work but youd have to test it.. but from what I heard 600 is cheaper than 550 so not sure why you would buy a 550 and change driver.. lol

Nope, you can't use the same mounting holes. The HLG-480 is 262x 125x 43,8mm while the HLG-600 is 280x 144x 48,5mm.But you can put it in the same place, drill four new holes and take self-tapping screws if you do not have a tap.
In terms of durability, it makes not a big difference whether the boards run at 137.5w or at 162.5w. You could glue a few additional c-channels on the backside to increase surface area and cooling capabillities but I don't think it's needed.

Thanks for your help. The board for the 600 is almost twice as long as it is wide, do you know if or how it covers a square area?

No, I don't know the HLG-600.
But these guys know how to build lights so it should cover a squared area quite nicely. Are there no recommendations on their website?

There are I'm just wondering how they come up with that footprint because I don't have a reflective wall on all sides

maybe you should look into building walls you will gain probably a good 5-10% with reflective wall and will also help getting lights deeper in the canopy

You could use black/white or white/white foil and let it hang from the ceiling to adjust the area to your needs. Its not the best reflective material but this foils are cheap and reflects up to 90% of the hitting light.
Just put a small strip of wood at the top and bottom of the foil, at the top for mounting to the ceiling and at the bottom, so it hangs tightly and does not flutter around.
