NUVO Lighting TH322 1-Light, MR16, 120V Track Head, Gimbal Ring, Black Finish

The TH322 takes a single MR16-shape lamp with a GU10 bi-pin base, rated up to 50W at 120V line voltage. No lamp ships with the head, so order the GU10 separately. Because it is a GU10 line-voltage socket, there is no transformer in the head and you do not use low-voltage MR16 bi-pin lamps in it.

No. The TH322 is rated for dry locations and indoor use only. Keep it out of covered exterior soffits, garages exposed to weather, bathrooms over showers, and any damp-rated application.

Yes. The head is halogen technology with a 50W maximum at 120V, and any line-voltage GU10 lamp at or below that wattage fits the socket, including LED GU10 retrofits. Dropping from a 50W halogen to a 6 to 8W LED GU10 is a common way property managers cut load on an existing track run without changing heads. Confirm your LED lamp's dimming capability separately, since dimming here follows the lamp.

Dimming on the TH322 is lamp dependent. The head itself has no driver or dimming circuit, so whether it dims (and on what dimmer) comes down to the GU10 lamp you install. A dimmable halogen GU10 will dim on a standard line-voltage dimmer; a non-dimmable LED GU10 will not, regardless of the dimmer.

Extension is 5.13 inches from the track, and the body measures 2.13 inches wide by 2.13 inches high. That is a compact head for tight ceiling plenums or low soffits, and the gimbal ring pivots the lamp inside that ring rather than swinging a long arm, so it needs little clearance around it to re-aim.

The TH322 is cETLus listed, which covers both US and Canadian requirements, and it is RoHS compliant. For a facility spec sheet, note it is a dry location, indoor, ceiling-mounted fixture.

A gimbal ring head holds the MR16 lamp inside a pivoting ring, so the lamp aims within the ring and the fixture stays close to the ceiling line. That suits retail display, artwork, and accent washes where you want the fixture visually small and the beam adjustable. A longer round-back or cylinder head projects further and shields the source better from glare at shallow aiming angles. The TH322 is the low-profile option at 5.13 inches of extension.

Glass and metal construction, and each head weighs 0.98 lbs. Light enough that loading a full track run of them is not a concern on a standard ceiling-mounted track, and the black finish hides heat marks and handling better than a white head on a commercial floor.

Yes, the TH322 carries a California Proposition 65 disclosure for lead. Institutional and government buyers who require Prop 65 documentation in the submittal should account for it.

Black is the finish offered on the TH322, and the head has no selectable CCT feature. Color temperature is set entirely by the GU10 lamp you choose, so if you are standardizing 3000K across a store you specify that at the lamp, not the head.
