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.

This Nelson GLS incandescent bulb has a red finish and a B22 bayonet cap with side pins. Its 240–250V 40W rating suits approved decorative lighting fittings, providing red coloured light rather than white general lighting.

This dimmable bulb measures 60mm in diameter and 105mm in overall length, with a 1,000-hour rated average life. Match the supply and use a complete fitting approved for a 40W incandescent lamp, with suitable heat tolerance, ventilation and clearance. For dimming, check the control's incandescent-lamp rating and minimum and maximum total connected load, counting every connected 40W bulb. Outdoor or festoon use requires a complete lighting system suitable for the installation and exposure. Switch off power and let the lamp cool before replacement.

Frequently Asked Questions

Can I dim a single Nelson red 40W bulb?

Yes. Use a control rated for incandescent lamps and check its minimum and maximum total connected load. One 40W bulb may be below some dimmers' minimum load. Count all connected bulbs and follow the control manufacturer's installation and derating requirements.

Can I use this red B22 bulb in outdoor or festoon lighting?

Only use it where the complete lighting system is suitable for the installation and exposure and approved for a 240–250V 40W incandescent bulb. Check heat tolerance, ventilation and clearance for its 60mm diameter and 105mm length. A matching B22 cap alone does not establish outdoor suitability. This bulb does not fit E27 or E14 screw sockets.

Does this bulb produce red light or warm white light?

It produces red decorative light through its red finish. It is a traditional GLS incandescent bulb, not a warm white bulb or an LED replacement. Use it in suitable decorative fittings where red coloured light is wanted.
