Litetronics PRT135N 1X4 LED Smart Light Panel Retrofit - 3500K

The Litetronics PRT135N LED Smart Light Panel Retrofit is designed to modernize existing fluorescent troffers with a plug-and-play LED solution that fits 1x4 configurations. It delivers a rated lumen output of 4500 and a color temperature of 3500K, offering bright, neutral-white lighting suitable for a variety of interior applications. With a 100,000-hour rated life and a high efficacy, this retrofit aims to reduce maintenance and energy costs over time while preserving the look of standard ceiling grids.

Key construction and design features include its DLC Premium and FCC-listed credentials, instant-on performance, dimmable capability, and a broad operating range. The kit is designed for quick installation—reportedly able to be completed by a single person in under two minutes without ceiling plenum disruption—thanks to a patented form factor that supports common 2’x4’, 2’x2’, and 1’x4’ fluorescent troffer sizes. The unit operates at 120–277 V and provides a 110° beam angle, making it suitable for general ambient lighting in many commercial spaces. It’s also rated for damp locations, expanding potential placements in garages, corridors, and other semi-wet environments.

Beyond hardware, the retrofit emphasizes connected control via LiteSmart, enabling occupancy sensing and daylight harvesting to reduce energy usage. The on-board sensor and wireless control options allow grouping fixtures, on/off and dimming functionality, and schedule-based scenes through a mobile app or a wireless remote switch. This makes it practical for facilities pursuing ongoing energy management and maintenance optimization while preserving a familiar ceiling aesthetic. The included 10-year warranty provides long-term protection aligned with its claimed long life and energy-saving potential.
