Need gardro to step and properly explain LEDs but lumens arent relevant to plants. I work off of PPF, aiming for 500-1000.
My LED is dimmable and for the first two weeks I run at 30w, slowly increasing to my max (130w total draw). I can run it 24/0 for 5 years without ever changing the bulb.
Factoring in a new bulb for HPS every year (£100ish) plus extra running costs, the difference over 5 years is huge. Its either 1 or 2 years before youve recuperated the initial spend. If I was upgrading my setup, id go 2x4 tent, 2 lights. Id be looking 8-10oz per cycle.
