Wide-flood 100° beam, generated from the IES file.
Frosted polycarbonate diffuser delivers a uniform 100° beam — one beam shape, ten lumen cells (two housings × five CCTs). Pick the housing and CCT below; peak candela, total lumens, and the IES filename update with the selection.
LDRR410-N2 4000K.IES
Built for the multi-fMILY ladder.
Drop-in companions for the Nebula-II Series — emergency egress, snap-on CS sensors, Gehry construction housings, and replacement trim rings in every fixture finish. Each one ships with the same ETL / JA8 / Damp pedigree as the luminaire it pairs with.

Documentation & Resources
Everything specifiers, contractors, and project managers need to spec, install, and certify the Nebula-II — from the data sheet on day one to the IES files on the bid sheet to the TAA certificate on the federal RFQ.
The full multi-fMILY collection.
Nebula-II is one luminaire in a thirteen-product collection engineered specifically for multi-family residential — in-unit living, corridors, baths & wet locations, and common amenity zones. Same factory, same CS controls platform, same JA8 / Title-24 / ENERGY STAR pedigree across every tier. If the Nebula-II isn't the right fit for a given zone, one of these is.
For the whole property.
Nebula-II handles in-unit and corridor. These cross-line fixtures handle everything else on the property — parking lot, walkways, garage, leasing office — same CS controls platform, same factory, same warranty. Specify them together for a single-source multi-family package.
Built for turn-over speed.
Hundreds of thousands ship from five US warehouses — 2-3 day QS lead means a unit refurb between tenants doesn't wait on lighting. Layouts back in 48 hours, quotes and rebate matches reply same business day. 12-pack cartons standard.
Stack the California rebates.
Nebula-II is JA8-2022 listed + ENERGY STAR qualified — the two hooks that unlock CalEnergyWise, PG&E / SCE / SDG&E utility rebates, and HUD multi-family programs. Typical offset on a property-wide retrofit: 20-50% of fixture cost. We'll match your APN and pull the paperwork.
