Nidaros 2120BL is an outdoor ceiling light shaped as a low cylinder, 12 cm in diameter and 9 cm high. The cast-aluminium body is powder-coated black (RAL 9005), closed underneath by clear safety glass with a silver reflector set deep inside. It shines downwards only, in a narrow 24° beam.
Where to mount it
Norlys designed Nidaros for horizontal surfaces – under eaves, on the ceiling of a canopy, terrace roof or gazebo – among other things for lighting walls and façades. The 24° beam concentrates the light on a limited area below the fitting instead of spreading it all around, and ULOR 0% (BUG B1-U1-G0) means no light goes upwards. The luminaire weighs 0.95 kg and is fixed through two holes according to the supplied instructions; the spacer 3084XX0009 is sold separately.
The terminals take conductors up to 3 × 2.5 mm², and up to 1.5 mm² for loop-through wiring, so the next fitting can be fed from the same line. The cable must have a round sheath of 7–10.5 mm diameter – with any other size the seal will not do its job. The luminaire is protection class I and must be connected to a protective earth.
How much light it gives
The integrated Lumens EDC 57C LED module is rated 10 W and 1051 lm; the whole luminaire draws 10.7 W and delivers 762 lm, i.e. 71.2 lm/W. That is roughly what an old 60 W bulb gave, but gathered into a narrow beam. 3000 K is a warm white, CRI 80 is typical for outdoor lighting, and SDCM3 means the white does not visibly differ between several fittings in one row. The module's L70 lifetime exceeds 59,000 h; the LED source is replaced by a professional service.
The light can be dimmed with an ordinary phase (TRIAC) dimmer – the manufacturer allows both trailing-edge and leading-edge control, so no separate control bus is needed.
Durability
IP65 means fully dust-tight and protected against water jets, so the fitting works outdoors without extra cover; the gasket is silicone. The operating temperature range is −20 to +45 °C. To order, Norlys makes it with 2700 K LEDs or in other RAL colours; as standard, model 2120 also comes in white, graphite and aluminium.
