Re: Quantum Board V3

I wouldn't buy anything on Alibaba except from Kingbrite. They have a solid reputation with tons of buyers feedbacks all over the internet. I haven't found any evidence that suggests they could be selling fake LEDs, but I'm not denying it is possible as most of the Chinese sellers does this. I have ...

Re: HLG 550 vs Slate2 heatsinks

Another question

If I want to run 6 boards at 70% ... do I need 3x HLG-240H with 2 boards per driver
or can I use 2x HLG-240H at 100% power, each driver powering 3 boards in series

Re: HLG 550 vs Slate2 heatsinks

Thanks for the reply,

Nice setup! Do you run the 6 boards at 100% or dimmed?

The Slate heatsink for 3 boards is 940mm so it means that my frame would be 37x37 in my 4x4 tent. Is this the optimal spread for 6 boards in a 4x4?

Re: IT'S ALIVE!!!! ( version 1.2 )

Nice setup!

What are you using for the floor? Does it absorb water and protect the floor?

Re: HLG-480H-48B wiring: series or parallel?

Thank you so much for taking the time to explain everything, it was very helpful! 2x HLG-240H-C2100B definitely looks like my best option. If I understand correctly, I would be getting 107w max per board, which is even better than the 70W per board that I would be getting if I used the original driv...

Re: HLG-480H-48B wiring: series or parallel?

sorry for the typo, yes I meant 4 qb288

how does 2 HLG-240H-C2100 compare to 1 HLG-480H-C1400B? Would I get the same lighting power & efficiency?

I am also wondering what is the difference between HLG-240H-C2100B and HLG-240H-C1400B?
