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 GLS LED bulb dimmable?

Yes, this LUSION GLS LED bulb features a built-in dimmable LED driver and is fully dimmable. It is compatible with most leading-edge and trailing-edge dimmer switches. We recommend testing with your specific dimmer before full installation, as compatibility can vary by brand.

What does this GLS LED bulb replace?

This 12W E27 GLS LED bulb is a direct replacement for a 100W E27 incandescent GLS bulb. It fits the same E27 Edison screw base and delivers equivalent warm white output at a fraction of the energy consumption, with a significantly longer 20,000-hour lifespan.

What is the difference between 3000K and 2700K warm white?

Both 3000K and 2700K are warm white colour temperatures, but 3000K produces a slightly crisper, brighter warm white light compared to the softer, more amber glow of 2700K. 3000K is well suited to living rooms, dining areas, and kitchens where a warm but clear light is desired, while 2700K is preferred for bedrooms and hospitality settings where a more relaxed, intimate atmosphere is required.
