The newest QB-130v2 uses 288xLM301B on the 92% efficient XLG-150-H-AB driver.
The diodes can achieve 3.03 μmol/J (approx. 224lm/W) efficiency at 65mA.
At 130W, the diodes are running at 0.15A, for 190.8lm/W pre-driver, 175.5lm/W post-driver, for approximately 2.5uMol/J efficiency.
eg. Compare to HLG-65v2 65W @ 2.35uMol/J (R3000), or HLG-100v2 100W @ 2.45uMol/J (R4000)
