NUVO Lighting TH633 12W LED Cinch Track Head, 3000K, Matte Black and Brushed Brass Finish

The TH633 is an H-style track head, so it mounts to H-type (3-wire, Halo-pattern) track. Its installation instructions are published as the TH633 H-Style Track Head instructions. If your ceiling runs J-type (Juno) or L-type (Lightolier) track, this head will not seat in it, and you'd need a head matched to that pattern.

No. The TH633 carries a Dry location rating only, so it has to stay in conditioned interior space. Keep it out of covered exterior areas, unheated porches, and wet or damp bathroom zones. It is safety listed cETLus for its rated use.

The LED is integrated, so there is no replaceable lamp and no socket. When the light source reaches end of life the whole head is swapped out. Average rated life is 30,000 hours, which at 12 hours a day of retail or lobby use runs close to seven years before replacement comes up. For facilities that prefer to stock lamps rather than fixtures, a socketed PAR-lamp track head is the better choice.

Each TH633 delivers 1020 lumens at 12 watts on 120V. That is roughly comparable to a 75W halogen PAR head in output while drawing a fraction of the power. For accent work over a display or island, installers typically space heads to overlap their beams rather than relying on one fixture, so plan on multiple heads per run and size the track circuit by total wattage: 12W each means a long run stays well inside a standard 20A branch.

Yes, the TH633 is dimmable on 120V line voltage. Because the LED driver is integrated into the head, it needs an LED-compatible (ELV or forward-phase LED) dimmer, not an old incandescent-only rheostat. Mixing it on a circuit with incandescent or halogen heads can cause flicker or a limited dim range, so a consistent set of heads on one dimmer is the cleaner approach.

The TH633 is a fixed 3000K warm-white head, not color-selectable, so it will read the same as other 3000K fixtures and will not drift if someone bumps a switch. Its CRI is 90, which renders merchandise, artwork, and wood tones more accurately than a typical 80 CRI head, so putting one next to an 80 CRI fixture on the same wall can show a visible difference in color quality even at the same temperature.

Extension is 5.25 inches, with a 3.88 inch width and 3.25 inch height on the head itself. Add your track height to the 5.25 inches to get total drop, which matters in low-ceiling retail or in corridors where head clearance and sightlines are tight.

Housing is aluminum and steel, finished in matte black with brushed brass accents, and the whole head weighs 0.57 lbs. The low weight means it won't overload a properly supported track run, and the metal body stands up to repeated reaiming better than a plastic-shell head. It is also RoHS compliant.

Yes. The TH633 is identified as containing lead for California Proposition 65 purposes, so a Prop 65 warning applies for projects and procurement records in California.

One finish combination: matte black with brushed brass. There is no other color offered on the TH633, so if you are standardizing a run of heads across several rooms, every unit will match without having to specify a finish code.
