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.

Check table chart

The National nls GLS halogen bulb delivers 630lm of 3000K warm white light through a clear rounded envelope. Rated 240V and 42W, it uses an E27 Edison Screw cap and has a visible internal halogen capsule.

Use this bulb in a fitting approved for E27 240V halogen lamps with a maximum lamp rating of at least 42W. Check the fitting's lamp clearance, ventilation and protective-cover requirements. Outdoor use requires a complete fitting approved for the location. When dimming, follow the control's halogen rating, minimum and maximum total connected load and derating instructions, counting 42W per lamp. Switch off the electricity supply and allow complete cooling before handling. Dispose of broken glass safely.
