2 x Bridgelux EB3 4000K 1.12m strips on flat bar aluminium. Total length is 1.2m, width is 20cm. Runs at under 30 degrees C.
1 x Mean Well HVG-65-42B LED driver, (5 year rated, 90% efficient)
3m cable between light and LED driver.
Measures 300 PPFD at 20cm, so this would be suitable for shelf growing, for early vegetative stage, or similar.
Note that even a free fluorescent fixture of equal intensity would end up costing more in total, in less than a year of use. The lifespan of this fixture is also about double that of fluorescent lights.
