The LT18T84840B1 is a high-efficiency LED T8 replacement designed to drop into existing fluorescent fixtures without rewiring. This 18-watt lamp delivers about 2200 lumens with a nominal 4000 K (neutral white) color temperature, offering a competitive 122 lm/W energy efficiency. The driver electronics are integrated within the end caps, which supports a compact, ballast-compatible design and helps provide even light across the length of the tube. With a rated life of up to 50,000 hours (L70), these lamps are positioned for long-term operation in commercial and industrial settings. The construction and thermal management are aimed at reliable operation, including thermal protection to guard against overload conditions.
This model is specified for use in non-wet locations and operates on a common line voltage range of 120–277 V, making it compatible with a wide swath of building electrical systems. It is non-dimmable and UL listed for safety compliance, with DLC listing indicating suitability for some utility rebate programs. The lamp’s T8 form factor and 4-foot length fit standard linear fixtures that previously housed fluorescent tubes, with a single-end bypass configuration in mind for simplified ballast eliminations where permitted by system design. Typical packaging is one lamp per package. While applicable to many commercial applications, potential buyers should verify ballast compatibility and local electrical codes before installation, and note the 18 W rating and 2200-lumen output when planning lighting levels and energy savings in areas such as offices, retail, schools, and light industrial spaces.
