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.

Double Check!

Ensure the replacement has the same wattage, as the physical length varies by power rating.

Frequently Asked Questions

What is a G23 fitting?

G23 is a 2-pin base fitting commonly used in compact fluorescent lamps (CFL). The two pins are spaced 23mm apart. It is found in desk lamps, under-cabinet lights, and dedicated CFL downlight fixtures. Note: G23 fittings are not compatible with standard E27 or B22 lamp holders.

What does the colour code 865 mean?

The colour code 865 indicates the bulb's colour rendering and colour temperature: 8 = CRI of 80+, 65 = 6500K colour temperature (cool daylight). This cool, bright light is ideal for task lighting, workspaces, and areas where clear, crisp illumination is preferred.

Is this bulb dimmable?

No, this FSL G23 compact fluorescent bulb is not dimmable. Standard CFL technology is not compatible with dimmer switches. Please use it on a standard non-dimming circuit.
