NUVO Lighting TH443 1-Light, LED, 12W Track Head, Pipe, White, 36 degree Beam

No separate lamp is needed. The TH443 uses an integrated LED, so the light source is built in and not replaceable. It draws 12W and delivers 1020 lumens, with an average rated life of 30,000 hours. When the LED eventually fails, you replace the head, not a bulb, which is worth knowing if you are standardizing a retail or office ceiling on a fleet of these.

No. The TH443 is rated for dry locations and indoor use only. A covered exterior walkway, a shower area, or anywhere exposed to moisture or condensation needs a damp- or wet-rated fixture instead. Keep this one to interior dry spaces like retail floors, offices, lobbies, and galleries.

Extension is 6.25 inches, which is the drop from the track to the fixture on its pipe stem. The head itself measures 3.38 x 2.38 x 2.38 inches and weighs 0.77 lbs. That 6-1/4 inch projection matters in low-ceiling spaces and in corridors where anything hanging lower becomes a head-strike or code clearance issue.

Yes, the TH443 is a dimmable LED head running on 120V. It still has to be paired with an LED-compatible dimmer on the circuit; a legacy incandescent dimmer can flicker or buzz with low-wattage LED loads. At 12W per head, keep the total connected load in mind, since many LED dimmers have a minimum load as well as a maximum.

A 36 degree beam is a flood-leaning spread. On the TH443 it works for washing merchandise groupings, shelving, and general accent over a seating or display area from typical ceiling heights. If you need to pick out a single piece of art or a jewelry case with a tight pool of light, choose a narrower beam head in the 15 to 25 degree range instead. For color-critical display, the 90 CRI output here renders fabric and skin tones well.

The TH443 carries a cETLus safety listing, which covers both US and Canadian requirements, and it is RoHS compliant. That cETLus mark is normally what an inspector or facility spec needs to see for a line-voltage interior luminaire. Note also that it carries a California Prop 65 notice for lead.

The TH443 is not CCT selectable, so there is no field switch for color temperature. The output is fixed at a single color temperature with 90 CRI. If you are adding heads to a run that is already installed, order to match what is up there rather than assuming you can dial it in later.

White is the only finish offered on the TH443, so every head on the order will match. Pair it with white track and white canopy components if you want the run to disappear into a white ceiling.
