CARISO WL-4 wall light black/gold LED 21 W Dim-to-Warm SLV 151740

CARISO WL-4 is a wall light shaped as a flat, angled shell 35 cm wide. Outside it is black and matt; inside it is painted gold — and because the housing is open at the top and the bottom, all of the light bounces off that gold surface first. This is not merely a finishing detail: gold warms the reflected beam where a white interior would cool it.

Dim-to-Warm is the point

The fitting does not just dim — it shifts colour together with brightness. At full output it gives 580 lm at 2700 K; at its lowest setting it drops to 58 lm and 1700 K, roughly candle-flame territory. That is how a classic incandescent behaved, growing warmer as it was turned down; most LEDs do not, and hold the same cool tone all the way down. A ten-to-one output range lets one fitting cover both evening reading and pure background light.

Control and light quality

CARISO WL-4 works with ordinary phase dimmers, both leading edge and trailing edge. It needs no controller and no external driver: it connects straight to 220–240 V, 50/60 Hz mains. Colour rendering is CRI 90 and the flicker metric SVM is 0.03 — low enough for desk work and for video.

Dimensions and mounting

The fitting is 35 cm wide, 10.4 cm tall and projects 11.1 cm from the wall. It weighs 1.103 kg net (1.479 kg gross with packaging). Mounting is surface, directly on the wall. The body is aluminium, protection class I requires a protective earth conductor, and IP20 restricts it to dry interiors.

Lifetime and service

The manufacturer quotes 30,000 hours to L70B50 — after which half of a production batch still holds at least 70% of its initial output. SLV lists the LED module as a separate spare part, number 916608, so a worn panel does not mean replacing the whole luminaire. SLV gives a five-year warranty on this model.
