Soft and wide rather than directed. The opal shade diffuses the bulb completely so the centre glows evenly, and the matte steel disc around it picks that light up and carries it outward, across almost 16 inches instead of leaving it at the shade. The result is a low-contrast wash that lights the wall as much as the room. It is an ambient light, not a task light.

One E12 candelabra bulb, not included. Go with 2700K for warm light or 3000K for a slightly cooler, brighter look. The bulb sits inside the opal shade so you never see it, which means the shape of the bulb does not matter here, only its colour temperature and output. Buy a dimmable one if you plan to put it on a dimmer.

No. The bulb is fully enclosed in opal glass, so there is no bright point to catch your eye. That is the reason opal is used on wall fixtures: on a wall you are usually looking straight at the light rather than up at it, and clear glass in that position is uncomfortable. The whole shade glows at an even brightness instead.

15.75 inches (400 mm) across, projecting 6.30 inches (160 mm) from the wall. That is a large sconce, closer to a wall-mounted disc than a small accent light, so give it a wall it can be seen on. The projection is the same as the smaller SLATE sconce, so it still works in a corridor.

In a hallway, living room or stairwell, 60 to 66 inches from the floor to the centre of the fixture puts it at roughly eye level, which is standard. Beside a bed, 30 to 36 inches above the mattress so the light falls on the page rather than in your eyes. If you are mounting several down a hallway, space them 6 to 8 feet apart and keep them at a consistent height.

The wave-formed disc is painted steel in a matte cashmere beige. The shade at the centre is smooth opal glass. Cashmere beige is a warm neutral that reads soft against white, off-white and plaster walls, which is usually what you want when several are mounted in a run down a hallway.

Beside a bed it works for comfortable reading rather than fine print. The opal glass spreads the light rather than focusing it, so you get a soft pool across the whole area instead of a directed beam on the page. If one person wants to read while the other sleeps, a directional lamp is the better tool. ONDA is for soft, even light you can sit under for hours.

Yes, with an external dimmer switch or a dimmable smart bulb. There is no integrated dimmer in the fixture, so you can use whatever system you already have. Worth doing beside a bed. If you are on a wall dimmer, make sure it is rated for LED loads.

Both use an opal glass shade, so both give the same soft, glare-free light. The difference is the disc and the scale. SLATE is an 11-inch dome on its own. ONDA sets a smaller opal shade in the middle of a 15.75-inch steel disc that carries the light outward, so it covers far more wall. SLATE is the quieter one for a tight hallway or a nightstand, and comes in four colours. ONDA is the statement piece for a wall that can hold it.

No, it's rated for dry locations only. That rules out bathrooms with a shower or tub, and anywhere else exposed to damp. A powder room with no shower is usually fine, but check your local code.

Yes. cUL listed for both Canada and the US, so it passes inspection and won't cause issues with insurance or a home sale. Made in Poland by TK Lighting.

It's a hardwired fixture that requires installation. If you're replacing an existing sconce on the same box, many people handle it themselves. If you're adding a new wall box, running new wiring, or converting a plug-in position, use a licensed electrician.

Turn it off and let the bulb cool first. A dry microfibre cloth handles dust on both the glass and the painted steel. For marks, a barely damp cloth and a dry buff. Don't spray cleaner directly at the fixture, spray the cloth, and keep abrasives away from the paint.
