Built for the RT05 modular system
LumenstarLED designed the RT05 as a platform: one screwless housing, one light engine, and a choice of trims that change the optics and the look. The RT05 Vertical Louver Trim (LS-RT05-VLVR-WT) is the white, louvered member of that family, made to the dimensional and mechanical specifications of the RT05 body so it seats cleanly with no visible screws and no gap around the opening. It secures in place quickly on site, which matters when you are finishing a full corridor of step lights in one afternoon. The trim is also offered in black and brushed nickel within the RT05 range, so you can keep one engine and change the face to match the millwork or the wall colour.
Light quality and glare control
Vertical louver blades are a classic optical strategy: they shield the LED from off-angle view while leaving the downward and forward beam wide open. In practice, someone walking down a stair or a hallway sees the lit surface, not the source. Paired with the RT05 engine's CRI greater than 90, the result is comfortable, honest colour on floors, treads and finishes — skin tones in a clinic, oak in a stairwell, stone in a lobby. The RT05 is available in 3000K warm white and 4000K natural white, plus RGB and RGBW versions for accent and wayfinding schemes, and it is dimmable, so evening levels can be dropped without losing the effect.

Installation and compatibility
This trim fits the RT05HV and RT05LV light engines — nothing else. Decide early which engine you need: the high-voltage version for a 100V AC circuit, or the low-voltage one for a 12V AC/DC run driven from a remote supply, which is often the easier path in stair risers and around water. Rough in to the 4-3/4" × 2-7/8" (121 × 73 mm) cutout, land the 12" (30 cm) leads in an accessible junction, seat the engine, then click the louver trim on last so it stays clean through drywall and paint. The IP67 rating and the -20°C~+45°C operating range mean the RT05 handles damp, dusty and cold locations, which is why it turns up in Canadian garages, covered entries, unheated stairwells and exterior steps as readily as in a finished hallway.
Applications and documentation
Think open-plan offices where low-level lighting must not reflect in screens, healthcare corridors where night-time glare wakes patients, boutique retail and hotels where the guest should feel the light and never see the source, plus home projects: basement stairs, deck steps, a hallway that no longer needs an overhead light at 2 a.m. For layouts, cutout confirmation and the full ordering options, the RT05 Screwless Step Light technical PDF is available in the Documentation tab of this page — check it with your electrician before you cut the wall, and order the trim colour that matches the rest of the job.
