LED Track Spot Light — Tech Spec

Adjustable spotlights that clip onto a ceiling track. Retail displays, gallery walls, museum vitrines, restaurant tables — anywhere you need to aim light at something specific rather than wash the whole room. The key things to get right: CRI (you're lighting products people are supposed to buy), beam angle (too wide and you wash out the display, too narrow and you miss it), and glare control (nobody wants a spot beam in their eyes while shopping).

Core Specs

Wattage: 7W / 10W / 12W / 15W / 20W / 25W / 30W / 40W. 20W replaces a 50W halogen AR111 and gives you more light with a better beam. 30–40W covers high-ceiling retail and gallery spaces.

Input: AC 100–240V for standard track. 48V DC for low-voltage magnetic track systems.

Efficacy: ≥ 95 lm/W standard, ≥ 85 lm/W for CRI 95 PRO-Ultra. The efficacy hit at CRI 95 is frustrating but physics — those red-boosting phosphors absorb light.

CRI: ≥ 80 standard, ≥ 90 PRO, ≥ 95 PRO-Ultra. For track lights in retail, CRI 90 is the minimum we recommend. You're using a track spot because you want to draw attention to something — don't undermine that with flat color rendering. PRO-Ultra at CRI 95 with R9 ≥ 80 is for jewelry, high-end fashion, and gallery/museum applications. The Citizen COB source in the PRO-Ultra gives a single-point beam with a clean cutoff that multi-chip arrays can't match.

CCT: 2700K / 3000K / 4000K / 5000K. 3000K is the default for hospitality and most retail. 4000K for fresh food (makes vegetables look crisp) and jewelry (brings out stone brilliance). Tunable white 3000K–5000K available for concept stores that change displays.

Beam angle: 12° (narrow spot, high ceiling accent, jewelry vitrine), 24° (standard retail accent), 36° (medium flood, shelf lighting), 45° (wide flood, larger displays), 60° (very wide). With a 12° beam at 5 meters, you're lighting a spot about 1 meter across. With a 36° beam, about 3 meters. Pick accordingly.

UGR: < 19 with the honeycomb louver or snoot accessory. These snap onto the front of the fixture and cut spill light outside the beam. Ugly but effective — and in a retail ceiling, nobody's looking at the fixture anyway.

Track compatibility: 2-wire single-circuit, 3-wire 3-circuit (lets you control three groups of fixtures independently on the same physical track), DALI track (4-wire), and magnetic low-voltage 48V track. The adapter is universal but you need to specify which track type at order — the internal wiring differs.

IP rating: IP20. These go in dry indoor ceilings. If you need a waterproof track spot for a covered outdoor retail walkway, we can do IP44 with a sealed housing — it's a different SKU, ask for it.

Housing: Die-cast aluminum heat sink at the front (where the LED sits), PC/ABS body at the rear. The heatsink does the actual work — after two hours at full power, the front housing should be warm to the touch but not hot. If a track spot is too hot to hold, the LED is cooking and the lifetime claim is fiction.

Reflector: High-purity aluminum, anodized, in specular (mirror) or semi-specular (slightly diffuse) finish. Semi-specular gives a softer beam edge, which is more forgiving for retail displays where the spotlight-to-ambient transition shouldn't be harsh.

Lens options: Clear glass (maximum output), frosted glass (softer beam, less defined edge), honeycomb anti-glare (cuts spill), linear spread lens (stretches the beam into an oval for shelf or painting illumination).

Finish: White RAL 9016, black RAL 9005, or silver-grey RAL 9006. In most retail ceilings, white disappears best. Black is for industrial/loft interiors or when the track itself is black.

Adjustability: 0–90° vertical tilt, 0–350° horizontal rotation. Tool-free — you turn a knurled ring, not loosen an Allen screw. Installation crews appreciate this.

LED chips: Bridgelux standard, Philips Lumileds PRO, Citizen COB PRO-Ultra.

Driver: Integral, built into the track adapter or luminaire body. This is the weak point of compact track spots — the driver is tiny, runs hot, and is the first thing to fail. We rate the driver at 30,000 hours rather than the 50,000 hours of the LED because physics limits how long a miniature driver packed into a track adapter can last. If you need longer driver life, we can remote-mount a larger driver in the ceiling void — tell us before you order and we'll spec it differently.

Dimming: Non-dim, Triac (most common for retrofit — works with existing wall dimmers), DALI-2, 0-10V, or push-dim.

Power factor: ≥ 0.90.

L70: ≥ 50,000 hrs at Tc 75°C for the LED, ≥ 30,000 hrs for the integral driver.

Operating temp: -10°C to +45°C.

Warranty: 3 years standard, 5 years PRO.

Certifications: CE, RoHS, CB.

If you're not sure which track system your ceiling has, send a photo of the track cross-section and we'll identify it. There are about six common track profiles and the adapters are not interchangeable.
