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.

The nls GLS halogen light bulb combines a classic rounded shape with a frosted finish and an E27 Edison screw cap. Rated at 240V and 28W, it provides a frosted alternative to a clear-envelope halogen bulb.

Use this lamp in a fitting approved for E27 240V halogen bulbs with a maximum lamp rating of at least 28W. Check the fitting's clearance, ventilation and installation instructions before replacement. Switch off the electricity supply and allow the bulb to cool completely before handling.

Frequently Asked Questions

What should I check before using this 28W bulb with a dimmer?

Check the lamp manufacturer's dimming instructions and the dimmer's approved lamp types before installation. Calculate the total connected load using 28W per bulb and keep it within the control's minimum and maximum ratings. Include the minimum-load requirement when selecting a control for one bulb.

What fitting does this nls GLS bulb require?

This bulb has an E27 Edison screw cap and a 240V, 28W rating. Use a fitting approved for this cap, supply and halogen lamp type, with a maximum lamp rating of at least 28W. Check bulb clearance and ventilation. Switch off the electricity supply and allow complete cooling before replacement.

How does this Frost bulb differ from a clear halogen bulb?

This bulb has a frosted envelope rather than a transparent outer finish. The frosted surface conceals the internal halogen capsule, while a clear bulb leaves it visible. This is a 28W halogen bulb, not an LED.
