About this product
Slight is Lumenwerx's collection of miniature linear luminaires — a 15/16"-wide extruded-aluminum profile equipped with a remote driver that delivers precise, glare-controlled illumination for drywall, grid, and wood-slat ceiling applications. It is offered in pendant (coaxial powered suspension), recessed (drywall mud flange), and surface mountings, the last with twist-clip T-bar (9/16" and 15/16"), tegular, screw-slot, drywall ceiling clip, and wood-slat bracket options. Pendant fixtures add a direct/indirect distribution; recessed and surface are direct only. Delivered output runs 200 to 600 lm/ft (indirect to 500 lm/ft), with efficacy published up to 78 lm/W. A six-optic menu tailors the light: High-Efficiency Lambertian (HLO), the patent-pending three-tiered Diamond Prism Optic in Matte Black (BDPO) and Graphite (GDPO), and Micro-Prism (MPO) on the direct side, plus Mini Widespread Indirect (MWIO2, 160° spread) and Mini Widespread Asymmetric Indirect (MWAI2) optics for the indirect uplight. Slight ships with static-white LEDs in 2700/3000/3500/4000/5000K at a minimum 80 CRI, with an optional 90 CRI with elevated R9 (3 SDCM), or a 95 CRI full-spectrum option enriched in the cyan 480 nm region for healthcare and circadian strategies. LM-80 testing shows L80 lumen maintenance greater than 60,000 hours. Fixtures are dimmable 100–1% via 0–10V standard, with Lutron Hi-lume 1% Eco, eldoLED 1% ECOdrive and 0.1% SOLOdrive, and DALI driver options, universal 120–277V input (347V with the RD1 driver), and PoE compatibility. Sections span 2 to 8 ft with virtually seamless continuous runs over 8 ft joined onsite with joiner kits. ETL listed to UL 1598 and CSA C22.2 No. 250.0 for indoor dry/damp locations, and backed by a five-year limited warranty.
