Bypassing the ballast allows the bulbs to operate in a voltage input range of 100 to 277 VAC.
LEDtronics Inc.’s UL-listed, omni-directional LED corn bulbs provide 360 degree illumination and drop into existing enclosed lighting fixtures, such as pendants, bollards and explosion-proof fixtures.
The LED post tops come in a white polycarbonate body with an aluminum heat sink. The bulbs, ranging in wattages from 9 to 120, replace incandescent, halogen and metal halide lamps that consume up to 400 W.
Bypassing the ballast reduces energy consumption and allows the bulbs to operate in a voltage input range of 100 to 277 VAC. They come in E26 medium base and E39 mogul base versions that handle temperatures between -20 to 65 degrees C.
The ROHS-compliant, UL-listed LED bulbs direct an even, omni-directional beam of 5,700 – 6,300 K pure-white illumination, with lumens ranging from 1,020 (9 W) to 15,600 (120 W).
Because LEDs have no filament, they’re shock and vibration resistant, and don’t require frequent switching. LEDs don’t emit large amounts of heat with little to no ultraviolet or infrared light.
