You appear to have the inside track here. I'm not sure why we're talking up an in increase in lumens. Those are visual spectrums not plant spectrums. Please explain how this benefits our plants.
For growers currently running the 300 watt version of the Luxim LEP it's suggested, to pick up weight, they add a second R/FR/IR source (while also running the 300 watt LEP) like the 1000 watt Phillips HPS lamp (which runs @ 1,200 degrees F) for flower since the LEP alone produces little in these regions. And that gets a bit pricey.
No disputing the LEP is a great veg lamp but does the new 500 watt LEP than eliminate the need for a separate flowering lamp? If so I'll do a side by side.
Thanks for sharing
