NORLYS Sol 4057GR Outdoor Ceiling Light LED 19.3W 3000K DALI2 Graphite Ø20 cm IP65

Sol 4057GR is a Norlys outdoor ceiling light shaped as a low cylinder, 20 cm in diameter and 11 cm high. The body of extruded aluminium profile and aluminium alloy is powder-coated graphite (RAL 7016), and a satin diffuser of UV-stabilised polycarbonate, sealed with silicone, closes it underneath.

Mounting and connection

The luminaire weighs 2.42 kg and is fixed to the ceiling through two ø5 mm holes 100 mm apart, following the supplied instructions. It projects 11 cm below the mounting surface, a figure to compare with the height of the eave or porch roof above an entrance.

The terminals take conductors up to 5 × 2.5 mm², and the supply can be looped on to the next fitting with cable up to 1.5 mm², so one line can serve several ceiling lights under one roof. The EPDM gland takes round cable 7–10.5 mm in diameter. It is protection class I, so the installation needs a protective earth conductor.

How much light and what kind

The Philips Fortimo LED module produces 2200 lm, and after the satin diffuser the luminaire delivers 1663 lm at 19.3 W. That is enough for the main lighting of a covered terrace or gazebo, not just a marker light at the door. 3000 K is warm white, CRI 80 is sufficient for outdoor spaces, and the satin finish spreads the light so that individual LEDs are not visible in the diffuser. The output falls symmetrically downwards and only 0.3% goes upwards.

The fitting has a DALI2 driver: brightness is adjusted digitally from a DALI installation, and an ordinary phase dimmer will not dim it. The manufacturer also allows a DC supply of 176–280 V.

Build and servicing

IP65 means dust-tight and protected against water jets, and IK10 means resistance to a 20 J impact. The manufacturer rates the light source at L70 above 50,000 h. The LED module and driver are replaced by a professional service, and Norlys offers separate service kits for this luminaire, ZS4043ZX0009 with the LED module and ZS4047ZX0009 with the driver, so one failed component does not mean replacing the whole ceiling light.
