About this product
Hemi is Lumenwerx's line of hemisphere-shaped miniature recessed downlights, offered in a small Hemi S (Ø 2" aperture) and larger Hemi L (Ø 3" aperture). Each recessed housing accepts adjustable and ambient light elements — single or dual light modules, with the total wattage of all modules capped at 21 W — delivering from 273 to 1338 lumens per element across 10°, 20°, 30°, 40°, and 50° beam angles. The LED source is available in 2700/3000/3500/4000K at 80, 90, or 95 CRI, with L80 lumen maintenance greater than 60,000 hours and SOLA dim-to-warm / DUO tunable-white options. Hemi recesses into drywall, grid, and trimless drywall-mudplate ceilings and dims via 0–10V (1% and 0.1%), TRIAC, ELV, Lutron EcoSystem, DALI, and DMX drivers. Baffle, trim-flange, and dome finishes (including custom) are offered. ETL listed to UL 1598 and CSA C22.2 No. 250.0 for indoor dry/damp and outdoor damp locations, and backed by a five-year limited warranty.
