Learn more by watching our NLS 20157 | 25W LED Tri Colour Slim Line Circular Fitting 2500Lm video.
The NLS 20157 is a 25W LED ceiling light rated for 240V AC, featuring tri-colour (3000K/4000K/6000K) tuning through a simple wall switch. The 20157 is dimmable and ultra-slim at 38mm high, ideal for low-clearance domestic and commercial ceilings. It complies with all Australian Standards and carries a 2-year warranty.
Kitchen and bathroom spaces often face the challenge of selecting a ceiling light that delivers brightness without consuming valuable clearance. Modern renovations and retrofits demand fittings that fit standard boxes while handling moisture exposure. The NLS 20157 solves this with a low-profile design, IP54 moisture protection, and a compact 38mm mounting that requires no ceiling modification.
Installers and renovators value the 20157 for its straightforward fit into standard 300mm ceiling openings and existing boxes. The tri-colour feature (3000K warm, 4000K neutral, 6000K daylight) lets end-users adjust the light character with a wall switch, a strong selling point on residential projects. The fitting offers solid value, with the 2500-lumen output and 25W draw proving efficient for kitchens and bathrooms alike.
The NLS 20157 is not suitable for outdoor or fully exposed wet locations; the IP54 rating covers indoor damp areas (kitchens, bathrooms) only, not exterior installations. Do not install in submersed, high-pressure washdown, or unenclosed verandah environments.

(20157)
The NLS 20157 offers three colour temperatures via a standard wall switch: 3000K warm white for evening and living spaces, 4000K neutral white for balanced task lighting, and 6000K cool daylight for detailed work. Simply press the wall switch to cycle through the three settings. No separate controllers or app required.
Installation of the NLS 20157 must be carried out by a licensed electrician, as it connects to mains 240V AC wiring and requires certification under the Australian electrical safety standards. The fitting itself is quick to mount into a standard ceiling box, but wiring and safety sign-off are legal requirements.
The NLS 20157 fits directly into standard Australian flush ceiling boxes (16mm or 20mm depth). No special brackets, adapters, or reinforcement is required on most domestic installations. Your electrician will confirm the ceiling box compatibility before installation.
Yes, the NLS 20157 is dimmable with trailing-edge (phase-cut) dimmers, which are the most common type in Australian homes. Standard dimmer switches used for incandescent or halogen lights will work with the 20157. Test the dimmer on site after installation; if flickering occurs, your dimmer may not be fully compatible with the LED driver.
The NLS 20157 has a rated lifetime of 40,000 hours, equivalent to roughly 13 years of typical domestic use (3 hours per day average). Sparky Direct supplies a 2-year manufacturer's warranty covering defects in materials and workmanship. Warranties do not cover installation faults, physical damage, or use outside the product's rated specifications.
The NLS 20157 carries an IP54 rating, which protects against dust and moisture splash in indoor damp areas like kitchens and bathrooms. It is not rated for outdoor use, exposed verandahs, or high-pressure washdown environments. Install only in enclosed indoor spaces where exposure to rain and hose spray is not a risk.
The NLS 20157 is supplied as a complete assembly, ready to install into a ceiling box. The package includes the LED fitting, diffuser, driver module, and stainless-steel fixings. No additional mounting brackets, extension leads, or trim rings are needed.
The NLS 20157 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.
