LED Spotlight Bulbs for GU10 and MR16 Installations

GU10 and MR16 are the two spotlight sockets found in most Australian homes and commercial installations. GU10 is a 240V mains socket used in recessed downlights, surface-mounted spotlights, and track lighting systems. MR16 is a 12V low-voltage socket that requires a transformer or driver to step the voltage down from 240V. The two sockets are not interchangeable.

Dulora's spotlight range offers two product families across both socket types. The FlexBeam has an articulating head that can be rotated before installation to set the beam direction, allowing the beam to be aimed at artwork, architectural features, or task surfaces before the lamp is fitted. It is available in warm white 2700K and soft white 3000K. The Sunset Dim spotlight brings the dim-to-warm effect to a spotlight form factor: starting at warm white 2700K at full brightness, it shifts automatically to 1800K as the dimmer is lowered, producing the warmth and ambience of a traditional halogen without the heat or energy consumption.

All models carry ultra-high colour accuracy. 240V GU10 models are SAA certified and work with most incandescent and LED dimmers; Dulora-sold dimmers are trailing-edge. 12V MR16 models require a compatible 12V dimmer or dimmable transformer. All models are flicker-free and covered by up to three years warranty. Free metro delivery on orders over $99, free regional delivery over $199.

Buying Guide

What is the difference between GU10 and MR16?

GU10 and MR16 describe the lamp socket and form, but they run on different voltages and cannot be interchanged. GU10 is a 240V mains socket: the pins twist and lock into the fitting, and the lamp runs directly from the mains supply. It is the most common spotlight socket in Australian homes built or renovated in the last fifteen years. MR16 is a 12V socket: the pins are straight and the lamp requires a transformer or driver to step the voltage down from 240V. MR16 systems are common in older Australian homes and some commercial installations. If you are replacing an existing lamp, check the voltage and socket type of your existing globe before ordering.

What makes the FlexBeam different from a standard spotlight?

The FlexBeam has an articulating head that can be rotated before installation to set the beam direction. Rather than being fixed in one position, the beam can be aimed at a specific surface, artwork, or architectural feature before the lamp is fitted into the downlight or track. This makes the FlexBeam suited to applications where direction matters: artwork lighting, display surfaces, and architectural features where a fixed-angle lamp would require a different fitting to achieve the same result. Available in warm white 2700K and soft white 3000K across both GU10 and MR16 socket types. 

What is the Sunset Dim spotlight?

The Sunset Dim spotlight is a dim-to-warm lamp: at full brightness it produces warm white 2700K light, and as you dim it, the colour temperature shifts automatically down to 1800K, producing the deep amber warmth of a traditional incandescent halogen at low output. This shift happens continuously across the dimming curve, with no scene setting or secondary switch required. The Sunset Dim spotlight is available in GU10 for 240V downlight systems and MR16 for 12V systems. Browse our Sunset Dim collection for the full dim-to-warm range across other lamp types.

Can I dim these spotlight bulbs?

All models in this collection are dimmable. The 240V GU10 models work with most incandescent and LED dimmers; Dulora-sold dimmers are trailing-edge, which is the correct driver type for LED loads. The 12V MR16 models require a compatible 12V dimmer or dimmable transformer: not all 12V transformers support dimming, so confirm your driver is dimmable before purchasing. The Sunset Dim models produce their characteristic warmth shift as you dim, so the dimmer itself is part of the effect. Browse our dimmers collection for compatible trailing-edge options.

Why does colour accuracy matter for a spotlight?

A spotlight concentrates light on a specific surface or object, which means the colour accuracy of the lamp has a direct and visible effect on how that surface reads. Artwork, joinery, fabric, food, and decorative objects all shift in apparent colour under a lower-CRI source. At the ultra-high colour accuracy levels found in this collection, the lamp renders colour with exceptional fidelity, so surfaces appear the way they would under natural daylight rather than being shifted toward yellow, red, or flat white. For art lighting, retail display, and feature lighting where the quality of the light on the subject is the point, this level of colour accuracy makes a material difference. Note that ultra-high colour accuracy is not the same as full-spectrum lighting: it means colours render accurately under the light, not that the light contains every wavelength of the visible spectrum.

Frequently Asked Questions

LED Spotlights

• What wattage do these spotlight bulbs replace?
• All 7W models replace a 50W halogen spotlight. Exact equivalent ratings are listed on each product page in the specification table.
• Are these spotlight bulbs dimmable?
• All models are dimmable. GU10 models work with most incandescent and LED dimmers using trailing-edge drivers; MR16 models require a compatible 12V dimmer or dimmable transformer. Check the product page to confirm compatibility for your specific installation.
• What is the CRI rating for these spotlight bulbs?
• FlexBeam models carry CRI97 and Sunset Dim models carry CRI95, both among the highest colour accuracy ratings available in LED spotlights. CRI ratings are listed on each product page. A high CRI is not the same as full-spectrum lighting; it means colours render accurately under the light, not that the light contains every wavelength of the visible spectrum.
• What is the beam angle of the FlexBeam?
• The FlexBeam has an articulating head that can be rotated before installation to direct the beam where it is needed. The beam angle and the head position are both adjustable. Check the product page for the specific beam angle specification for each model.
