Built to live outsideThe M2 is a fully sealed low-voltage luminaire rated
IP67, which means the light engine is protected against dust and immersion — the level of sealing you want in a deck riser that gets snow piled against it or a stair edge that catches every rainstorm. Its operating range of
-20~+45°C (-4~113°F) covers most of what a Canadian season throws at a exterior
step light, from a February cold snap to a July heat wave on a south-facing patio. Mounting is recessed and tool-friendly: drill a
13/8" (35mm) cutout, feed the wire, and the
pressure-fit stainless steel clips hold the fixture firmly in wood, composite or drywall-free framing.
Light quality that guides instead of glaresTwo SMD LEDs deliver
75 lumens at
5000K, a cool, daylight-toned white that reads as clean and modern and makes step edges easy to distinguish at a glance. The
120° beam spreads that output wide so a single fixture covers a full tread or a good stretch of deck board, and a
CRI greater than 85 renders colours faithfully — cedar stays warm, grey composite stays grey, landscaping stone keeps its texture. At only
0.5W per unit, the goal is guidance and ambience, not floodlighting, which is exactly why the M2 works so well as safety lighting that never feels harsh.

Wiring, dimming and compatibilityThe M2 is a
12V DC fixture, so it needs a low-voltage power supply sized for the total load of your run — with a 0.5W draw per light, even a small driver handles a full staircase. It is dimmable when used with dimmable power supplies (120V dimming or low-voltage dimming options), letting you drop the level for evening entertaining. For a full automated staircase effect, the
Controller Pro for staircase lighting manages up to 28 steps with smooth on/off and step sequencing, with adjustable mode, brightness, delay and speed. The light engine is compatible with multiple trim options across the M-Series: choose the
40mm louver round trim in white to aim light downward, the
40mm honeycomb round trim in white to shade the source from the eyes, or add the
white diffuser lens for RD12 for a softer wash.
Where to use it, and documentationThink backyard deck stairs and railings, a basement staircase leading to a walkout, a garden path lined in the
inground housing for RD12, a pool deck edge, a condo balcony, or the entrance steps of a café, clinic or boutique hotel where code-conscious guidance lighting matters. Contractors like it because one small cutout and a single low-voltage run finish a whole flight of stairs. If you need a smaller output for tight spaces, compare it with the
mini step and deck LED engine. The complete technical PDF spec sheet for LS-RD12-2-5K, including dimensions, trims and power supply options, is available in the Documentation tab.
