Larson Electronics offers the LEDT8-28W-V1 28-watt LED tube bulb, which delivers 2,750 lumens and is available in 5600K and 4300K color. This bulb replaces T8 and T12 fluorescent bulbs. Available in a nominal four-foot length, this high lumen output LED tube has an internal driver, meaning the bulb does not require and additional external driver. Operators simply connect either 120/277 VAC or 12/24 VDC directly to the lamp to energize it, according to the company.
