Cella 2" is the slender 2-inch-diameter member of Lumenwerx's Cella decorative cylinder family, an architectural luminaire that brings clarity and rhythm to spaces through its vertical form. The cylinder is paired with acrylic diffusers offered in 2" and 4" heights and in fully frosted or partially frosted finishes, delivering visually comfortable illumination for both accent applications and larger architectural installations where repetition reinforces spatial organization. It is available in pendant (flat round, conduit-feed, direct-mount, and deep round canopies with an 18"–72" PVC power cord) and surface configurations. The 450 lm package draws 5.5 W (about 82 lm/W at 3500K) from a custom mid-flux LED array offered in 1800K, 2200K, 2700K, 3000K, 3500K, 4000K, and 5000K with a choice of 80+ CRI or 90+ CRI (elevated R9 on 90+ CRI), color consistency held within 2 SDCM and LM-80-tested L80 lumen maintenance beyond 60,000 hours. Beyond static white, Chromawerx SOLA single-channel dim-to-warm (3000K–1800K or 2700K–1800K) and Chromawerx DUO two-channel tunable white (6500K–2700K or 5000K–2700K) circadian options are offered. Dimming runs to 1% via 0–10V, ELV, TRIAC, DALI, and eldoLED canopy drivers, with remote-driver options adding Lutron Hi-lume 1% EcoSystem, DMX, and Lutron DALI-2, plus an optional emergency battery and PoE compatibility. Finished in matte white, matte black, champagne, dark bronze, or a custom RAL color, 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.
