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.

Equivalent Wattages Between Different Light Bulbs

As long as the technology developed, a LED light bulb can only use 8 watt power but light up similar brightness when a incandescent light bulb uses 60 watt power. 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

Is this EiKO MR8 halogen bulb dimmable?

Yes. Use a dimmable 12V transformer and a halogen dimmer compatible with that transformer. Each bulb draws 20W. Keep the combined lamp load within both devices' minimum and maximum ratings, including when operating a single bulb.

Can this bulb connect directly to 240V mains?

No. This 12V bulb requires a compatible 12V transformer or power supply. It uses a GZ4 two-pin base and needs a matching fitting rated for at least 20W. Check the 25mm diameter, 35mm length and fitting's heat-clearance requirements before installation.

What distinguishes this MR8 bulb from larger reflector bulbs?

This MR8 bulb has a compact 25mm reflector and a 23° directional beam. It produces 84 lumens of 2700K warm white light and uses halogen technology, not LED. Its size, GZ4 base and 12V supply must match the light fitting.
