A finishing piece built for one job
The RT05 screwless louver trim is not a universal trim ring: it is the dedicated face of the LumenstarLED RT05 step light platform. The louver geometry sits proud of the aperture just enough to block the direct sightline to the LEDs, so what you see on the wall is a soft wash of light rather than a bright dot. That matters most at eye level in stairwells and corridors, where a bare recessed source is uncomfortable to walk toward. The black finish is one of the three trim colours available on the RT05 series, alongside brushed nickel and white, which lets a designer keep the same engine throughout a building and simply change the face plate to suit each space.
Screwless mounting, faster installs
Conventional trims need screws, a driver and a steady hand to sit flush. The RT05 trim uses a tool-free clip system that seats and locks onto the light engine, which means no exposed fasteners on the finished wall and no scratched finish from a slipped bit. For electricians running a stairwell with a step light at every landing, or a hospitality corridor with a long run of them, that difference shows up directly in labour hours. It also makes service simple: the trim comes off for cleaning or engine access and clips back on without new hardware.

Compatibility and installation
This trim is engineered to fit the RT05HV and RT05LV light engines exclusively — the high-voltage and low-voltage versions of the same body — so the fit is flush and repeatable from one unit to the next. Rough-in follows the engine: respect the 4-3/4" × 2-7/8" (121 × 73 mm) cutout, run the wiring to the 12" (30 cm) leads, set the engine, then clip the louver trim on last so it never takes abuse during drywall and paint. Because the engine is offered in both 100V AC and 12V AC/DC, confirm which version you have before ordering drivers or transformers; the trim itself is the same face for either one. With an IP67-rated engine behind it and an operating range of -20°C to +45°C, the assembly is at home in damp or exposed locations as well as conditioned interiors.
Where it works and what's documented
Think condo and apartment stairwells, basement stairs in a renovated home, home theatre aisles, hotel and long-term care corridors that need low-level night lighting, restaurant steps, retail display platforms and office egress paths. With >90 CRI and a choice of 3000K warm white or 4000K natural white at the engine — plus RGB and RGBW options for accent work — the light stays true to wood, stone and paint colours while the black louver keeps the source out of sight. The full technical spec sheet (RT05 SCREWLESS STEP LIGHT) is available in the Documentation tab of this page for cutout dimensions, electrical data and the c ETL us listing. Add the black trim to your RT05 order and keep one spare per floor — it is the part that makes the whole installation look finished.
