The Domus BF-7577 is a 450mm raw ceramic wall light the widest inthis group taking one E27 lamp and supplied unpainted.

Nearly half a metre of wall from a single lamp

At 450mm this is the widest single-lamp ceramic in the range,and that is the thing to weigh before buying it.

• A wide, soft band of light one E27 behind a long aperture gives a gentler,more even wash than a small fitting straining to cover the same width.
• The output has to spread further. Where a 200mm fitting concentrates onelamps light, this one distributes it so it reads as ambient rather than bright.Do not expect it to be a task light.
• Which is usually what you want on a big wall a bright patch on a broadsurface looks worse than an even one.
• Give the lamp the output. An E27 LED at 10W rather than8W is worth it across this width.

Two sources give two different maximum wattages

• The datasheet says 60W. Our record says 20W.
• It is not a one-off: 11 of the 12 E27 raw ceramics in this rangecarry exactly this conflict. The exception, the BF-2440, has a sheet that genuinely reads20W CFL which looks like the source the other eleven werecopied from.
• We work to the datasheets 60W, and anE27 LED at 810W sits comfortably under both readings anyway.
• Ask us before a circuit-load calculation.

The height is not recorded

We hold the width (450mm) and the projection (150mm) andno height. We will not guess it. The 150mm projection is the deepest inthis batch combined with 450mm of width, this is a substantial object on a wall, someasure the space properly. Ask us and we will measure a fitting.

Choosing the lamp not supplied

• E27 LED, 10W, 27003000K, enclosed-rated.
• Check it fits the cavity. E27 LEDs vary in length and girth; a compact globe issafer than a long candle or a large decorative shape.
• CRI 90 if the wall is a colour more so here, because there is more wallin the light.
• E27, not E14.

Where it works

• A broad living-room or hallway wall this needs the width to look right.
• Above a bedhead, where a wide even wash and no visible lamp is exactly thebrief.
• A stairwell landing with a generous wall.
• Not on a narrow pier 450mm will overrun it.
• Not on a poorly finished wall and over 450mm, every ripple shows.

Questions

Will one lamp light 450mm properly?

It will light it evenly rather than brightly, and on a wall this wide that is the better result a bright patch on a broad surface looks worse than a soft band across it. Treat it as ambient light, not task light. Because the output has to spread further than on a small fitting, spend on a 10W E27 LED rather than an 8W one; the difference is more visible here than it would be on a 200mm fitting.

Is the maximum 20 watts or 60 watts?

The datasheet says 60W and our record says 20W. We checked whether it was isolated: 11 of the 12 E27 raw ceramics in this range carry the same conflict, and the twelfth the BF-2440 has a sheet genuinely reading “20W CFL”, which looks like where the 20W came from. We work to the datasheet’s 60W. In practice an 810W E27 LED sits under both, so it only matters for a circuit-load calculation ask us if that is what you are doing.

How tall is it, and how far does it stand out?

The projection is 150mm, the deepest in this group, and the height is not recorded we will not publish a guess for a dimension that decides clearance under a rail or a cornice. Combined with 450mm of width this is a substantial object on a wall, so measure the space carefully. Ask us and we will measure a physical fitting for you.

Should I get this or a smaller one?

Wall width decides it. On a broad living-room or hallway wall, 450mm reads as deliberate and a small fitting reads as an afterthought. On a narrow pier this will overrun and look crowded the BF-7310 at 230mm or one of the compact G9 fittings is the better call there.

Will any E27 globe fit?

The base will, the body might not. E27 LEDs vary considerably in length and girth and the ceramic cavity is fixed, so a long candle or a large decorative globe can foul it. A compact globe shape is the safe choice or send us the lamp you are considering and we will check it against the fitting.

Do I have to paint it?

No the raw ceramic is a deliberate look and many are left as they arrive. It is porous until painted or sealed, so it marks. At 450mm it is also a large surface to keep clean, which is worth thinking about if it sits at hand height.

Can it go in a bathroom?

No. Raw ceramic is porous until painted and the fitting is rated for indoor dry use only. For a bathroom, ask us for something with an IP rating suited to the zone.
