Additional related video.
The National Light Sources 20224TRI is a 15W LED dimmable downlight rated 240V 50Hz. It produces 1350 lumens with a 120-degree beam angle. The 20224TRI offers selectable colour temperature: 3000K (warm), 4000K (neutral), or 6000K (daylight). It works with leading and trailing edge dimmers. It complies with MEPS AS/NZS 4847.2-2010 and mounts recessed with a 110mm cut-out.
Downlight retrofits are common on renovation sites, especially when existing holes are larger than the standard 90mm. When a homeowner or sparky upgrades old halogen fittings, they often face a choice: enlarge the hole or find a downlight that fits the existing aperture. The 20224TRI fits the less common 110mm hole, avoiding extra ceiling cutting. Colour temperature control (warm, neutral, or daylight) sits at the base of the fitting with no dimmer module needed, letting homeowners adjust the light tone to suit the room.
Tradies value the 20224TRI for its simplicity: it comes with driver, flex, and plug ready to use. Once a licensed electrician installs a surface socket in the ceiling, the customer can swap the downlight out in minutes with no rewiring. The colour control sits at the fitting base, so no controller module is needed, keeping labour time and material costs low. The 50,000-hour lifespan and two-year warranty make it attractive for rental properties and multi-unit work where callback frequency matters.
The National Light Sources 20224TRI is not suitable for recessed installations with cut-outs smaller than 110mm without an adaptor ring. It is not rated for fully recessed, non-abutted insulation contact in uncavitated ceilings where clearance is less than 50mm. Do not install in bathrooms, shower enclosures, or fully external locations subject to direct rain or hose spray; the IP44 rating permits protected external use only.
Verified Sparky Direct customer reviews: National Light Sources 15W TRI COLOUR LED Dimmable Downlight 1350lm 110mm Cut Out | 20224TRI
"So much cheaper than the Bunnings equivalent." — Nige
"Good quality nice and bright." — Winnie
"Great downlight. We replaced existing halogen downlights that had a cutout greater than the standard 90mm, therefore we needed the 110mm. These downlights did the trick. They look modern and give a much better LED light than the old halogens. Certainly recommend them." — Dean
(20224TRI)
Yes, the 20224TRI is dimmable with both leading edge (conventional) and trailing edge (electronic) dimmer modules. It works with standard dimmer packs and dimmer switches commonly installed on Australian switchboards.
The 20224TRI offers three selectable colour temperatures: warm white (3000K) for ambient lighting, neutral white (4000K) for task lighting, and daylight (6000K) for bright, energising illumination. Colour selection is made at the base of the fitting and requires no dimmer or controller module.
A licensed electrician is required to install the surface power socket into your ceiling and connect it to your lighting circuit. Once the socket is in place, the downlight simply plugs in. The plug-and-play design eliminates the need for rewiring during replacement or adjustment.
Yes, the 20224TRI has a 110mm cut-out diameter and is designed for recessed ceiling installations with 110mm apertures. It does not fit standard 90mm holes without an adaptor ring. If your hole is smaller than 110mm, you will need to enlarge it or use an adaptor.
The 20224TRI is rated for 50,000 hours of operation, equivalent to 15+ years in typical residential use (3–4 hours daily). This long lifespan reduces replacement frequency and maintenance calls compared to halogen downlights.
The 20224TRI is rated IP44 and is suitable for protected external locations and interior use. It is not rated for direct water spray, bathrooms, shower enclosures, or fully external locations exposed to hose spray or heavy rain. For wet areas, use an IP65-rated downlight instead.
The National Light Sources 20224TRI 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.
