Beware of unscrupulous merchants when buying metal halide lamps. The inside of the shell of metal halide lamps is actually a mercury lamp, and the price is very low.
Rhein lighting has developed a new line of led grow light. It is equipped with Samsung LM301B diodes and built-in FORT UL driver. The grow light draws 640 watts from the wall,achieving the efficiency 2.8 μmol/J and higher average PPFD with 1300 μmol/s at 5'x5' flowering coverage.
