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

What is the difference between the Cool Daylight and Warm White variants?

The Cool Daylight Globe (SKU 5488) produces 6500K cool daylight light at 830 lumens — bright and crisp, ideal for kitchens, bathrooms, offices, and task lighting. The Warm White Globe (SKU 5485) produces 3000K warm white light at 400 lumens — softer and more inviting, suited to living areas and bedrooms.

Do I need the lamp holder as well?

If your existing downlight fitting already has a working 4-pin ballast/lamp holder, you only need to replace the globe. If your lamp holder is faulty or missing, select the Lamp Holder option (SKU 5490) to purchase a replacement ballast unit.

Is this bulb dimmable?

No, this ecobulb 4-Pin Nano CFL is not dimmable. Standard compact fluorescent technology is not compatible with dimmer switches. Please use it on a standard non-dimming circuit.
