Built as a matched component, not a generic cover
The RT05 Scoop Trim in black is an OEM-matched accessory for the LumenstarLED RT05 platform. Recessed lighting lives or dies on fitment: a trim that is a millimetre off leaves a shadow gap, catches dust and looks amateur. This trim is dimensioned for the RT05 body and its screwless mounting approach, so the edge sits flush against the finished wall or riser. The scoop geometry — an angled, swept opening rather than a flat ring — shields the eye from the diode while throwing light forward onto the tread or the floor, reducing glare in low-mounted positions where fixtures sit right in your line of sight.
Light quality and electrical details of the RT05 platform
Behind the trim, the RT05 light engine delivers 145 lumens from just 2W or 2.2W, with a CRI greater than 90 for accurate rendering of stone, hardwood and painted surfaces. Colour temperature choices on the platform are 3000K warm white and 4000K natural white, plus RGB and RGBW versions for accent and colour-change work. The engines are offered in 100V AC (RT05HV) and 12V AC/DC (RT05LV) versions, both dimmable, so you can tune a stairwell down to a soft night-level glow. Each engine ships with a 12" (30 cm) wire lead for connection inside the box or to a low-voltage run.

Installation and compatibility
Rough in the opening to 4-3/4" × 2-7/8" (121 × 73 mm), run your feed to the 12" (30 cm) lead, seat the light engine, then finish with the scoop trim. Because the trim ships separately from the engine, you can decide the look late in the project — black for a dark stair core, another finish elsewhere — without changing the rough-in. Confirm your voltage first: the RT05HV is the 100V AC version and the RT05LV is the 12V AC/DC version fed from a low-voltage supply. This trim fits those two engines and no others, so there is no cross-shopping or shimming required on site.
Where it earns its keep, and documentation
Think basement and condo stairwells, hotel corridors, restaurant banquette bases, retail fitting-room alcoves, home theatre steps and covered outdoor entries. The IP67 rating and the -20°C to +45°C operating range of the RT05 platform mean it handles wash-down floors, damp basements and cold Canadian shoulder seasons, while the c ETL us Listed certification keeps inspectors happy on commercial jobs.
