LED Corn Bulb, 12/18/27W, Up to 4050 lm, 3CCT, E26, 100-277V, Ballast Bypass, UL

The Euri Lighting ECB27W-303SW LED Corn Bulb gives contractors, electricians, property managers, facility teams, and commercial buyers multiple lighting configurations in a single lamp. A built-in wattage control allows selection between 12W, 18W, and 27W, while a separate CCT switch provides 3000K Warm White, 4000K Bright White, or 5000K Cool White. This 3-wattage x 3-CCT design creates nine possible operating combinations from one replacement bulb. Light output varies by wattage and selected color temperature. At 27W, output ranges from 3,645 to 4,050 lumens; at 18W, from 2,484 to 2,790 lumens; and at 12W, from 1,680 to 1,908 lumens. The manufacturer lists replacement applications ranging from 30W to 60W CFL and 50W to 100W metal-halide lamps, depending on the selected wattage. Designed for commercial and property-maintenance applications, the lamp operates across AC 100-277V, uses a standard E26 medium base, and provides a wide 360° beam angle. The ballast-bypass design incorporates a built-in driver, making it suitable for compatible retrofit projects after the existing ballast is bypassed according to installation requirements.
