Product Overview
LEDlescent 360 SELECT T8 signage lamps are direct-wire, ballast-free LED replacements for traditional high-output fluorescent T8 and T12 sign lamps. LEDs on both sides provide 360° omnidirectional illumination, while the rotating R17d bases allow the light distribution to be optimized for single- or double-sided signs.
The on-site CCT selector provides 4100K, 5000K, or 6500K output. These lamps operate directly from 120-277 VAC after the existing ballast is bypassed and are designed as UL classified luminaire conversion components for signage retrofit applications.
Compatible Applications
- Single-sided illuminated signs
- Double-sided illuminated signs
- Fluorescent T8HO and T12HO signage retrofits
- UL Type B direct-wire sign conversions
