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 bulb dimmable?

No, this Lightstar GU10 compact fluorescent bulb is not dimmable. Standard CFL technology is not compatible with dimmer switches. Please use it on a standard non-dimming circuit.

What is the difference between 5000K cool daylight and 4000K cool white?

5000K (cool daylight) produces a bright, crisp, bluish-white light that closely resembles natural daylight. It is ideal for task lighting, kitchens, bathrooms, and offices. 4000K (cool white) is slightly warmer and less blue, providing a neutral white light. This bulb is 5000K cool daylight.

Is there an LED equivalent for this GU10 CFL?

Yes, LED GU10 bulbs are available as a more energy-efficient and longer-lasting alternative, typically using 5-7W to produce equivalent light output with a lifespan of 15,000-25,000 hours. Consider our range of GU10 LED bulbs for further energy savings.
