30% of LED grow light manufacturers publish no lifetime data. Of those who do, 45% don't say whether the figure is L70, L80, or L90.

Those aren't equivalent. An L70 system at 40,000 hours is delivering 30% less PPFD than it was on day one. You're paying full electricity costs for 70% of the light.

Our new article gives greenhouse operators the tools to cut through the noise:
