Highlights & Features

retroⒶRCH-L1: Highlights & Features

Three angles anchored against the volume-tier fluorescent-strip retrofit set — volume-tier fluorescent retrofit kits. Install speed, config flexibility, reliability · numbers from datasheet pg 1-4.

— Hero Highlight

Industry's Fastest Strip Retrofit Kit Installation. In Minutes.

3-step lay-in install per datasheet pg 4: connect wirings → install junction housing → turn ON. Universal fit to 4.25" / 5.25" T8/T12 housings · built-in seismic hooks — no per-fixture bracketry, no opened housing. ~3 min/fixture vs 20+ min for full-fixture replacement — 50-fixture project = 14+ contractor-hrs · ~$1,200 labor offset at $85/hr loaded. Volume-tier fluorescent retrofit kits all wire-nut.

Configurability

9 configurations per bundle. Two bundles per length. 38 outputs across the LLSR family.

3-WATTSELECT × 3-CCTSELECT (3500/4000/5000K) = 9 outputs/SKU via dip-switch. ES3 Energy-Saver 18-30W (4FT) / 38-54W (8FT) · PS3 Power-Saver 35-45W / 65-90W. Same SKU lands warm-3500K → cool-5000K. Volume-tier fluorescent retrofit kits ship 1-25 configs with complex dip UX. retroRCH-L1 = the contractor-friendly sweet spot.

Aluminum · Damp · Warranty

6063 aluminum + IP40 Damp Location + 7-year warranty.

6063 extruded aluminum frame + aluminum PCB — runs cooler than cold-rolled-steel + fiber-glass-PCB competitors · longer L70 maintenance. IP40 Damp Listed opens parking decks · mech rooms · cooler exteriors · grocery back-of-house (volume-tier fluorescent retrofit kits all ship dry-only). 7-yr / 75,000-hr warranty — +2 yr vs every named competitor. Color-shift <180K per ANSI C78.377-2017.

contrLS

Total Adaptive Control.

retroRCH-L1 ships contrLS-Ready out of the box — integrated MSM-SDI/3/BLS bi-level microwave occupancy sensor · RM-SD/100S IR remote for on-site commissioning. PRO-tier Bi-Level path · ASHRAE 90.1 + Title 24 compliance · 0-10V dimming · no commissioning, no gateway, no app. BLS-only on the LLSR family per datasheet pg 4 (vs Hallmark's full 3-platform BLS / CS / SILVAIR matrix). 10-20% energy savings on top of the LED swap.

Drop-in occupancy + bi-level dimming — no commissioning, gateway, or app required. PIR (MSP-BLS) or microwave (MSM-BLS) sensors mount directly to the retroⒶRCH-L1 integrated sensor receptacle. IR remote (RM-HT/06S) for on-site commissioning. ASHRAE 90.1 and Title 24 occupancy reduction compliance out of the box.

Everything that ships with every retroⒶRCH-L1.

Per datasheet pg 3 · every base SKU ships with the LLSR luminaire · Junction Housing (driver pre-wired) · Aircraft Cable · built-in seismic hooks for lay-in T-bar grids. Optional EM driver · BLS sensor · IR remote · surge protection per §8 Accessories.

Qty 1 · Assembled
retroⒶRCH-L1 Luminaire
6063 extruded aluminum frame · aluminum PCB with Seoul 3528 LM80 LEDs · shatter-resistant polycarbonate frosted lens (factory-installed). 3-WATTSELECT + 3-CCTSELECT dip-switches preset to bundle-max wattage and 5000K. White (standard) finish.
Standard · Included
Junction Housing
UL-listed driver enclosure with the LED driver pre-wired inside — Junction housing for LED driver and aircraft cable for installations are included, standard per datasheet pg 3. 0-10V dimming · >0.9 PF · <15% THD non-flicker.
Standard · Included
Aircraft Cable
Suspended-mount aircraft cable with toggle clips for installations where the existing fluorescent housing's mounting tabs aren't usable. Ships standard in every retroⒶRCH-L1 box per datasheet pg 3 — no separate accessory order.
Built-In · Lay-In Ready
Lay-In Seismic Hooks
Datasheet pg 1 main feature: Easy Installation w/ Lay-In Ready and Built-In Seismic Hooks. The hooks integrate into the housing chassis — engages T-bar grid for one-handed install, secures the assembly against seismic disturbance per code, no per-fixture bracketry.
Optional adders — constNT EM driver (EM08-CMB/48EDC 8W BBU), in-line surge protector (10SP-277 / 20SP-277), contrLS BLS sensor (MSM-SDI/3/BLS microwave bi-level), and IR remote (RM-SD/100S) — ship in their own boxes per the §8 Accessories selections. Eco-conscious contractor packaging is standard on every retroⒶRCH-L1 carton.
Accessories

Engineered Accessories

Three accessories per datasheet pg 4 — EM08-CMB/48EDC 8W BBU (90-min) · MSM-SDI/3/BLS bi-level microwave sensor (ASHRAE 90.1 + Title 24) · RM-SD/100S IR remote. Junction Housing + Aircraft Cable already ship standard per §7 In the Box.

3 cards above · complete Compatible Accessories table per datasheet pg 4. The Junction Housing and Aircraft Cable ship standard in every retroⒶRCH-L1 box (no separate accessory order — see §7 In the Box). Hallmark’s 3-platform sensor matrix (BLS / CS / SILVAIR NLC) does NOT apply to retroⒶRCH-L1 — per datasheet pg 4, BLS is the only sensor compatibility tested for the LLSR family.

Three lamparRCH paths to LED

Three paths to commercial-interior LED.

retroRCH-L1 = the lamparRCH PRO retrofit path. Hallmark (LLSN) = new-build linear strip · Eureka (LV3P) = NEMA 4X / IP66 / NSF wash-down vapor-tight. Same brand · same warranty · same factory.

Round Out the Project

For the complete commercial-interior retrofit.

retroRCH-L1 handles the fluorescent-strip retrofit. These cross-line fixtures handle the rest — outdoor parking + entry, office / classroom / breakroom panels, emergency egress, exit signage. Specify together for one coherent commercial-interior package.
