Built for open high bay fixturesThe LED-8132M50CD belongs to Light Efficient Design's 8130 / 8132 / 8136 screw-in high bay retrofit family, a series available in 90W, 135W and 150W models replacing up to 400W HID. This 135W version is
open rated, meaning it is expertly engineered to work efficiently in open fixtures and damp environments while staying protected against insects and dust. Its
fanless design means silent operation with no moving parts to clog or fail — and it also means this lamp is intended for
open fixtures only, not sealed or enclosed housings. The lamp body measures 10.0" x 8.7", a familiar footprint for classic aluminum HID reflectors and pendant high bays.
Light quality and outputAt
5000K, the light is a clean daylight white that mimics natural daylight, sharpens perceived brightness in tall open spaces and helps keep crews alert through long shifts. With
80+ CRI, colour-coded wiring, inventory labels, paint work and quality-control inspections all read accurately. The
19,200 lumens produced from only
135W replace up to a
400W HID source, and unlike metal halide there is no warm-up and no restrike delay: flip the switch and you get full output instantly, which pairs beautifully with motion sensors.

Electrical, installation and controlsInstallation is a true lamp swap: shut off power, remove the old HID lamp, verify the fixture is open type, then thread the LED-8132M50CD into the
EX39 mogul socket. The USA designed and specified LED driver is pretested, potted and burnt in three times prior to shipping, and it is protected against vibration and moisture — a real advantage above conveyor lines, overhead doors and press equipment. The multi-volt
120-277V input covers 120V single-phase panels and 277V commercial feeds alike, and it also works on 208V and 240V. For
0-10V dimming, run the dimming pair to the lamp's wired circuit for smooth control down to 20%, and use the integrated
12V auxiliary output to feed an occupancy or daylight sensor so aisles dim when nobody is there. Dynamic temperature control supports a longer, brighter life.
Applications, family and documentationThink distribution centres and racking aisles, machine shops, welding bays, arenas and gymnasiums, big-box retail, municipal garages, hangars and agricultural barns — plus unheated Canadian docks where the -40°F rating matters. Within the same family you can mix wattages and colours across one building: the
135W 4000K LED-8132M40CD for a warmer white, the
150W LED-8130M40CD for higher ceilings, or the
90W LED-8136M40CD where 250W HID fixtures are being converted. For outdoor areas of the same site, the brand's shoe box and wall pack retrofits such as the
110W shoe box / wall pack retrofit use the same EX39 approach. The full technical PDF for the 8130 / 8132 / 8136 series, with the complete ordering table, is in the Documentation tab.
