Description

The GX53 LED bulb is a 75mm diameter disc-style bulb delivering 600 lumens from a 5.7W LED at 3000K warm white. The GX53 twist-and-lock base fits downlights and under-cabinet fittings designed for low-profile bulbs, particularly those with shallow ceiling voids or cabinet depths of 50-70mm. The bulb's 24mm height makes it one of the thinnest GX53 options available.

Designed for recessed ceiling downlights, under-cabinet kitchen lighting, and shallow display case fittings, the GX53 provides general ambient light rather than directional task light. The 600-lumen output suits hallways, utility rooms, and secondary lighting zones where 40-50W halogen equivalents were previously used. The bulb is non-dimmable and delivers consistent brightness on standard 230V mains circuits.

The white plastic housing dissipates heat across the rear fins visible in the image, keeping the bulb cool to touch after extended use. At 5.7W the bulb draws approximately 90% less energy than the 50W GX53 halogens it typically replaces, reducing electricity costs in fittings that run for several hours daily. The 3000K colour temperature produces a soft warm white comparable to traditional incandescent bulbs, avoiding the cooler blue-white tones of higher-temperature LEDs.

Frequently Asked

Is this bulb dimmable?

No. This GX53 LED is non-dimmable and must be used on standard on/off circuits only. Using it with a dimmer switch may cause flickering, buzzing or complete failure of the bulb.

What's the halogen equivalent brightness?

At 600 lumens the bulb is broadly equivalent to a 40-50W GX53 halogen. The exact perceived brightness depends on the reflector design of the fitting, but this output suits general ambient lighting rather than high-intensity task lighting.

Will it fit my existing GX53 downlight?

The bulb uses the standard GX53 twist-and-lock base found in most low-profile downlights and under-cabinet fittings. The 24mm height is shallower than most GX53 halogens, so it will fit fittings with limited ceiling void or cabinet depth. Check that your fitting's spring clips or retaining ring can accommodate a 75mm diameter bulb.

What colour temperature is 3000K?

3000K is warm white, producing a soft yellowish-white light similar to traditional incandescent bulbs and halogen lamps. It sits between the warmer 2700K (closer to candlelight) and the cooler 4000K (neutral white). 3000K is the most common choice for residential living spaces, bedrooms and hospitality environments.
