WAC Lighting 20.25" Trio LED Bathroom Vanity or Wall Light

Both. The Trio WS-51820 is listed for vertical or horizontal mounting, so you can run it across the top of a mirror or stand it up as a sconce on either side. It is a wall mount fixture and hardwired, so a junction box has to be located where you want it. Overall the fixture measures 20.25 inches long by 5.25 inches high, and the backplate is the full 20.25 inches, so a vertical install needs at least that much clear wall beside the mirror.

Yes. The Trio WS-51820 has a universal voltage driver concealed inside the fixture rated 120-240-277V, so the same part number works on residential 120V and on 277V lighting circuits in a commercial building. No separate transformer or remote driver to specify.

It needs an electronic low voltage (ELV) dimmer. A standard incandescent/forward-phase dimmer is not the right control and can give you flicker or no dimming range. With an ELV control the integrated LED dims smoothly and continuously. Spec the ELV dimmer on the order if the room is getting dimming control, since the fixture has no onboard dimmer.

The Trio WS-51820 carries a damp location rating and is IP44 rated, which covers bathrooms (outside the shower enclosure) and covered exterior locations like a porch or breezeway. It is not a wet location fixture, so keep it out of direct spray and off uncovered exterior walls.

Yes, it is listed as ADA compliant. The fixture projects shallow enough to be used in corridors and restrooms where protruding-object limits apply. It is also ETL and cETL listed, which covers US and Canadian installs.

Yes. The Trio WS-51820 is listed as both Title 24 compliant and Title 20 compliant, so it can be used on California projects where the inspector is checking lighting for those requirements. It is not Energy Star listed, so if a rebate program requires Energy Star specifically this fixture will not qualify for it.

The Trio WS-51820 delivers 1522 lumens at 19.58 watts in a 3000K warm-white, with a flood distribution from three illuminated elements. That is a reasonable single-fixture output over a standard single vanity. Over a wide double vanity most designers run two fixtures, or mount one vertically on each side of the mirror, which this fixture supports since it can be installed either orientation.

The light source is an integrated LED, not a lamp in a socket, so there is no bulb to replace. It is included and rated 50,000 average hours. For an MRO or property management standpoint that means no relamping cycle, but at end of life the fixture itself is the replacement item. At roughly 3 hours a day of bathroom use, 50,000 hours is decades of service.

One configuration: chrome finish, 3000K, ordered as WS-51820-CH. The backplate is polished chrome with three chrome plated illuminating elements, so it pairs with chrome or polished-nickel faucets and mirror trim. If the rest of the room is matte black or brushed brass, this is not the fixture to match it.

Aluminum base with flexible composite diffusers over the three light strips. The composite diffusers are not glass, which means less breakage risk in high-traffic commercial restrooms and spas than a glass-shaded vanity fixture.
