Built to last, built to breatheThe LUNA 3.5" starts with a durable airtight aluminum body — no flimsy plastic — paired with an anodized blue heat sink that maximizes airflow around the LED light source. Cooler LEDs mean steadier lumen output and colour over time, which is why this
LED pot light carries a projected life of 70% @ 33,000 hrs and a Lifetime warranty. Two spring-loaded clips are included so the fixture grips any ceiling material, and the whole assembly slips into a Ø 3 5⁄8" (92 mm) hole cut with a 4 3⁄8" (111 mm) overall diameter, 3 3⁄8" (85 mm) and 3 1⁄16" (78 mm) body dimensions and a 4 3⁄16" (106 mm) / 15⁄16" (34 mm) hardwire box profile.
Light quality and the dim-to-warm effectThe 12 watt LED module produces up to 600 lumens with a typical
CRI of 90, so colours read honestly — an important detail above a kitchen island, a retail display or a bathroom mirror. What sets this SKU apart is dim-to-warm: the colour temperature travels from 3000 K down to 2000 K as you dim, mimicking the warm glow of a halogen or incandescent source at low levels. The lens delivers a controlled
38° beam spread, tight enough for accenting a counter or artwork, soft enough for general room lighting when the fixtures are spaced properly.
Electrical, driver and installationPower comes from an extruded aluminum hardwire box housing a 300 mA dimmable Class II electronic LED driver with 100-135V AC, 50/60 Hz input and a power factor greater than 0.90. An 18" (457 mm) FT6-rated cable with a DC 2.1 connector links driver to fixture and is approved for use in plenums and suspended ceilings. Three "Quick connect" push-in terminals make wiring fast — a real time-saver when you're installing a dozen
recessed downlights in one afternoon. Dimming is TRIAC/ELV; for compatible dimmers, consult the manufacturer's LUNA dimmer list. Operating temperature range is -20°C~40°C (-4°F~104°F).
