It really comes down to photon flux ensity. PAR is barely a piece of the entire equation.

Simply put, you may gain efficnency, but you lose overall photon output.

Were this the case, my 50w panels should be something like 30w, not the 47w they're pulling (just BARELY under 1w per diode, fan included.) The 50w is pushing almost the same photon flux density as the 90w at 60w, just BARELY under it. In theory, the 50w should perform very similar to the 90w.
