Quantum Board Power Handling Test

This video covers the results of an experiment I did in order to determine how much power it’d take to destroy an HLG QB288 and QB304 Quantum Board. I was pretty damn surprised!



  1. Seems like voltage is what will destroy the board or running with no heat sink.

      If I had an “A” type 600H-54, I could have killed it, as this type would allow me to bump up the voltage. I bet if I got it to 55V it would pull waaaay too much current. No heat sink would likely also do the trick. I will try both in my next attempt 🙂
