Series 3 Samsung LM301H 500W

The Series 3 Samsung LM301H 500W is Budget LED's big fixture: four full-spectrum boards of Samsung LM301H diodes, dimmable from 50 to 500 Watts, on a 26" x 20" x 3" frame.

Coverage is 4.5' x 4.5' in flower and 6' x 6' in veg, and the mounting height goes up to 24-36 inches above the canopy — further than the smaller boards want, because there is more intensity to spread. Samsung rate the diode at a PPE of 3.03 μmol/J with anti-sulfurization.

Still passive-cooled at this size, still a kit — boards, driver, heatsink, dimmer, hanging kit and wiring — with a 3-year warranty. Budget LED put it against a single-ended 1000 Watt HID.
