Roughly, the lux ranges below are best suited to their corresponding stage of the growing cycle:
• Clone and seedling stage: 5,000–7,000 lux
• Vegetative stage: 15,000–50,000 lux
• Flowering stage: 45,000–65,000 lux

I have a lux meter and when switching to led I followed all of the conversion charts I could find with shitty results. I broke down and bought a par meter and was instantly able to dial in and my plants immediately loved life again.

Did you get light bleaching on yours? I had a lux meter from a mate and while it dialed in the CFL pretty well, I got light bleaching on my same wattage quantum boards.

No bleaching, but the plants weren't happy. I think it may have been the ir diodes being to close. I tried everything I could to make a lux meter work but was not satisfied. I broke down and bought a par meter and my plants instantly responded when dialed in to proper par. I'm not a fan of technology and don't like wasting money, but for me the par meter was well worth it. Without it I would have just gone back to hps.
