Colour Temperature

Colour temperature is measured in Kelvin (K) – the lower the number, the warmer the white light appears, while a higher Kelvin will appear cooler. Colour temperature generally ranges from 2700-3300K (warm) to 3300-5300 (cool) – and 6500K is daylight.

There is equivalent wattage between different light bulbs. To stop making confuse, you need to know what wattage equivalent to each other. See the table attached as below.

Frequently Asked Questions

Will this bulb fit my existing downlight housing?

This MR20 GU10 bulb has an overall length of 100mm and a 50mm diameter. Please ensure your downlight housing accommodates this length before purchasing, as MR20 recessed downlight housings vary in depth. If your housing is shallower, a shorter GU10 bulb may be more suitable.

Is this bulb dimmable?

No, this MR20 GU10 LED bulb is non-dimmable. Using it with a dimmer switch may cause flickering, buzzing, or reduced bulb life. Please ensure your downlight circuit is connected to a standard non-dimmed switch.

What is a GU10 fitting and is this a direct halogen replacement?

GU10 is a twist-lock fitting with two pins spaced 10mm apart. It is the most common fitting used in recessed downlights and track lighting in Australia. This 10W LED bulb is a direct replacement for GU10 halogen spots, fitting the same socket and delivering equivalent or better light output at up to 90% less energy.
