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 MR16 LED bulb dimmable?

Yes, this MR16 GU5.3 LED bulb is dimmable. It is compatible with most 12V LED dimmer switches. Please ensure your dimmer is rated for LED loads and 12V operation, as standard 240V dimmers are not compatible with this bulb.

What transformer or driver does this MR16 bulb require?

This bulb operates at 12V and requires a 12V transformer or LED driver. It is compatible with most electronic low-voltage (ELV) transformers. We recommend using an LED-compatible transformer to ensure stable performance and full dimming range.

What is the beam angle and what is it best suited for?

This bulb has a 30° narrow beam angle, making it ideal for accent lighting, display lighting, artwork illumination, and task lighting where focused, directional light is required. For wider area illumination, consider a 60° beam angle MR16.
