The interior LED replacement bulb for an 18-inch fluorescent fixture will last 12 times longer than the standard fluorescent tube. The state of the art Pulse Width Modulator (PWM) guarantees the same light output regardless of voltage fluctuations (11-16 volts). The replacement bulb is 200% more energy-efficient than the fluorescent counterpart (draws 623 milliamps) and gives off a brighter 810LMS output, as well as better light quality at 4500 kelvin.
Patented smart ratchet design allows you to direct the light to the most optimal locations. This allows the bulb to operate cooler and produces no noisy humming sound. Its easy 2 wire installation makes no need to cut out or damage the ballast of your current fixture. The built-in Fresnel lens spreads the light evenly, up to a 160-degree angle. No mercury, Led, or any other harmful chemicals in the product. This product is FCC approved and will not interfere with radio/analog signals.
