About this item
About this item
- EMERY™ STRATUS Output: Delivers 3,800 lumens at 30W at 126 lm/W peak efficacy — fixed 4000K neutral white, CRI 80+. Replaces higher-wattage fluorescent fixtures with a slim, hard-wired 1×4 panel.
- Efficacy Leadership: 126 lm/W at 30W places the DI-ST40-38L-1X4 among the highest-efficacy fixtures in the 30W 1×4 panel class — delivering more light per watt than comparable fixed-wattage alternatives.
- Ultra-Slim Profile: Panel depth of 0.36″ with bracket arm assembly at 1.61″ overall — integrates cleanly into shallow plenum and tight ceiling applications where depth is constrained.
- DLC QPL Listed: Qualifies for utility rebate programs in most U.S. markets. Visit designlights.org and search DI-ST40-38L-1X4 to verify eligibility with your utility provider.
- 0–10V Dimming: Supports 0–10V continuous dimming for adjustable ambient and task lighting levels — compatible dimmer required, sold separately. Backed by a 5-year limited warranty.
