Additional related video.
The NLS 20111BLK is a 10W dimmable LED downlight rated 240V 50Hz, delivering 950 lumens of brightness with switchable colour temperature (3000K, 4000K, or 6000K). It features a black metal trim ring, 90mm cut-out, and is IC-4-rated for safe installation under insulation.
Tri-colour downlights address a common challenge in residential and commercial retrofits: the uncertainty of which colour temperature suits the space. The 20111BLK lets you select the colour on the back of the unit before installation, making it simple for electricians to keep one versatile model in the van as a replacement fitting across multiple projects. No wiring changes needed — just flip the switch to change 3000K warm white, 4000K off-white, or 6000K daylight.
Sparkies value the 20111BLK for jobs where the customer hasn't committed to a final colour scheme. The brightness—950 lumens from 10W—suits domestic living areas, kitchens, and bedroom applications without the power draw of older halogen fittings. It pairs well with leading-edge and trailing-edge dimmers, giving end users full control over mood and ambiance after installation. The price point supports solid margins on renovation work while staying competitive against other premium LED options.
The NLS 20111BLK is not suitable for outdoor exposed locations, wet areas, or splash zones. The black trim is durable in coastal environments but not rated for direct salt spray or unprotected outdoor eaves. Install indoors only, in ceilings with standard insulation coverage and airflow.
Verified Sparky Direct customer reviews: NLS 20111BLK (20111BLK)

Installation of the NLS 20111BLK must be performed by a licensed electrician in accordance with AS/NZS 3000. The 90mm ceiling cut-out requires precision drilling and safe handling of the mains wiring. A licensed installer ensures correct polarity, earthing, and dimmer compatibility.
The tri-colour selector is located on the rear of the 20111BLK housing. Before fitting the downlight into the ceiling, slide the selector to your chosen colour: 3000K (warm white), 4000K (off-white), or 6000K (daylight). Once selected and installed, the colour cannot be changed without removing the unit. Check with the customer to confirm their preference before installation.
The NLS 20111BLK is compatible with both leading-edge (incandescent/halogen) and trailing-edge (electronic) dimmers. It will not work with old-style rheostat or autotransformer dimmers. Test the dimmer on site before installation to confirm smooth operation without flicker. If the existing dimmer is unknown, upgrade to a modern dimmable switch to avoid compatibility issues.
The 20111BLK has a black metal trim ring and delivers 950 lumens; the NLS 20111 white-trim model delivers 900 lumens. Both are 10W, tri-colour dimmable, and IC-4-rated. The black finish suits contemporary interiors and coastal locations where white plastic can yellow. Choose 20111BLK for aesthetics; both perform identically for brightness and dimming.
The NLS 20111BLK has a rated life of 50,000 hours, equivalent to roughly 10–15 years of domestic use at 5–8 hours per day. The LED module and driver are integrated and cannot be serviced. When end-of-life approaches, the unit must be removed and replaced as a complete assembly. Recycling of LED components is recommended.
The National Light Sources 20111BLK is available online from Sparky Direct, with Australia-wide delivery to any state or territory including regional areas. Sparky Direct is an Australian electrical wholesaler established in 2005, supplying more than 500,000 customers with transparent trade pricing.
