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 clear halogen light bulb delivers 630lm of 3000K warm white light. This 240V 42W lamp combines a classic A-shaped glass envelope with a visible halogen capsule and a B22 bayonet cap.

The dimmable bulb measures 55mm in diameter and 97mm long, with a 2,000-hour rated average life. Use in a complete fitting rated for a 240V 42W halogen lamp. For exterior use, install in a fitting designed for the location and providing the required weather protection. Follow the fitting's heat, ventilation and clearance requirements. For dimming, observe the control's halogen-lamp rating and minimum and maximum total connected load, counting each connected 42W bulb. Switch off power and allow the bulb to cool fully before replacement.
