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 National nls GLS halogen bulb provides 380lm of 3000K warm white light through a clear glass envelope. It has a B22 bayonet cap and a 240V, 28W rating for fittings designed for this halogen lamp type.

The bulb measures 55mm in diameter and 97mm in overall length, with a rated average life of 2,000 hours. Match the cap, supply voltage, lamp type and dimensions to your fitting, and follow its maximum wattage, heat, ventilation and clearance requirements. When dimming, observe the control's halogen-lamp rating and minimum and maximum total connected load, counting 28W per bulb. For outdoor use, use a complete fitting approved for the location and protected from weather. Switch off power and allow the bulb to cool completely before handling.
