NUVO Lighting TH491 LED, 12W Forged Track Head, White, 36 degree Beam Angle

Track system compatibility is the first thing to settle on the TH491. It is a 120V ceiling-mounted track head, so the track it clips into has to be a 120V line-voltage system of the matching groove type. The head itself is an integrated LED unit with no lamp to source separately. Check the mounting instructions at the Satco link published with the fixture before ordering a quantity.

No. The TH491 is rated for dry locations and indoor use only, so it should not go in a damp or wet spot, including covered exterior walkways, bathrooms with showers, or unconditioned porches. For those areas you need a fixture carrying a damp or wet location rating.

The TH491 delivers 1020 lumens at 12 watts. That output sits in the range of a typical 75 watt halogen PAR lamp, so on an accent or retail display run it replaces older halogen heads at roughly a sixth of the draw. Rated life is 30,000 hours.

A 36 degree beam is a flood pattern, wide enough to wash a painting, a shelf bay, or a merchandise table without hard edges, but still directional enough to read as accent light rather than general illumination. For tight pin-spotting on a single small object you want a narrower spot beam instead. With a CRI of 90, colors and fabrics render accurately, which is why this head suits galleries, showrooms, and retail.

Yes, the TH491 is a dimmable 120V LED head. Because the driver is integrated, the dimmer has to be one rated for LED loads, and on a track run you size the dimmer against the total wattage of all heads, 12 watts each. Mixing it on a circuit with legacy incandescent dimmers is where flicker and dropout usually come from.

Extension on the TH491 is 6.25 inches from the track, with a head body measuring 3.00 by 2.75 by 2.75 inches. That drop matters in low-ceiling retail or in a corridor where head clearance is tight, and it also tells you how much aiming room you have before the head fouls a soffit or a shelf edge.

No. The TH491 is not CCT selectable, so the color temperature is fixed at the factory. If you are adding heads to an existing run and need them to match, order the same model so the light stays consistent across the track. For a job where the spec is still open on color temperature, choose a selectable-CCT head instead.

The TH491 is cETLus listed, which covers both US and Canadian safety requirements, and the fixture is RoHS compliant. That is usually what a facilities or institutional reviewer is looking for on a commercial track job. Note that it is labeled under California Prop 65 for lead.

Aluminum. The TH491 uses a forged aluminum body, which both holds the aim position under repeated adjustment and carries heat away from the integrated LED. The head weighs 0.64 lbs, light enough that a standard track run supports a full line of them without concern.

White only. If you are matching heads on a run that uses a black or brushed nickel track, the white body will read as a visual break, so either standardize the whole run on white or pick a head offered in the finish already installed.
