Built-in PIR · The /P Variant
10 seconds. 1 minute. 10 minutes. You pick.
Order the LSMT615-S5E/P variant and the disk arrives with a factory-integrated PIR motion sensor at the rim plus a second dip switch on the back — three selectable hold positions covering the full multifamily occupancy spectrum. No power-pack. No low-voltage controller. No wall-switch sensor. One SKU, one install, three behaviors. The standard LSMT615-S5E ships without a sensor — pair with a wall-switch occupancy sensor or wire to an EM driver for code-required egress (see Section 7).
10-second hold — flick on, off when you leave. The right pick for storage closets, mechanical rooms, utility rooms, IT closets, and trash chutes — anywhere a brief lighting cycle matches a brief occupancy cycle. Saves the most energy of the three settings (PIR-triggered lighting in storage spaces averages ~35% of always-on burn). Set position 1 on the back-of-disk dip switch before fixture install — flip the lens off, toggle, flip back on, done.

120° even back-lit beam. Two sizes, five CCTs.
eCrescent ships a single 120° wide-flood beam from the back-lit polycarbonate diffuser — one beam shape, ten lumen cells (two sizes × five CCTs). Pick the size and CCT below; peak candela, total lumens, and the IES filename update with the selection. The polar plots below are synthesized from the Datasheet lumen matrix using a 120° wide-flood cosine model; 10 real IES files (5 per size) ship on disk under /IES/LSMT{4|6}{10|15}-S5 ({CCT}K)_IESNA2002.IES — legacy S5 filename suffix, photometric output identical to the S5E eCrescent SKUs.

Three things in the box. Eleven things in the catalog.
The eCrescent's value-tier story isn't just the fixture — it's the conversion kit + mounting hardware that ship in every box, the five constNT EM drivers that let you bring code-egress lighting down to ECO pricing, the full Leviton + Lutron approved-dimmer ladder for matched-dimmer compatibility, and the 24-pack contractor cartons at multifamily-friendly $/unit.

LSMT410-S5E + LSMT615-S5E.The full multi-fMILY collection.
eCrescent 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 / Damp-Location pedigree across every tier. If eCrescent isn't the right fit for a given zone, one of these is.
For the whole property.
eCrescent handles the indoor + wet-zone ceilings — corridors, hallways, balcony soffits, entries, patios, baths, and code-egress paths. 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. 24-pack contractor cartons standard.
Stack the California rebates.
eCrescent is JA8-2022 listed and ENERGY STAR certified — the hooks that unlock CalEnergyWise, PG&E / SCE / SDG&E utility rebates, and HUD multi-family programs. Typical offset on a property-wide retrofit: 20-40% of fixture cost (eCrescent is ECO tier — not DLC, so commercial rebate ladders that require DLC don't apply; ENERGY STAR + JA8 paths do). We'll match your APN and pull the paperwork.
