Sol 4053BL is an outdoor ceiling light shaped as a low cylinder 20 cm in diameter and 11 cm high, powder-coated black (RAL 9005). The underside is closed by a round satin polycarbonate diffuser that spreads the light and hides the LED module.
How much light, and what kind
The manufacturer gives two figures: 2200 lm for the LED module alone and 1655 lm leaving the fitting through the satin diffuser, at a consumption of 19.3 W. That is a little more than an old 100 W incandescent bulb gave, i.e. main-light level for a covered terrace, a carport or an entrance under the eaves. The light is symmetrical and directed downwards: only 0.3% of the flux goes up (BUG rating B1-U1-G1).
The colour temperature of 3000 K is warm white, CRI is 80, and the manufacturer states negligible flicker (Pst ≤1, SVM ≤0.4). The fitting can be dimmed with a trailing-edge or leading-edge phase dimmer – the driver is built in.
Installation and connection
The light is screwed to the ceiling through two ø5 mm holes spaced 100 mm apart. The terminals take conductors up to 3 × 2.5 mm², the gland a round cable 7–10.5 mm in diameter, and further fittings can be looped through with conductors up to 1.5 mm². The inrush current is 2 A for 50 µs. The fitting is protection class I, so it must be connected to a protective earth. It weighs 2.42 kg.
Build and service
The body combines an extruded aluminium profile with a die-cast aluminium alloy part, and the polycarbonate diffuser is UV-stabilised. IP65 means dust-tight and protected against water jets from any direction, and IK10 is the highest impact resistance on that scale. The LED module keeps at least 70% of its flux for more than 50,000 h. Module and driver are replaced by a professional service; the manufacturer offers separate service kits: ZS4043ZX0009 with the LED module and ZS4046ZX0009 with the driver.
