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 Osram Classic A GLS incandescent bulb has frosted glass that obscures the filament compared with clear glass. It provides 2700K warm white light with a 1340lm output and is dimmable.

Rated at 230V and 100W, the bulb has an E27 Edison screw cap, measures 60mm in diameter and 105mm in overall length, and has a rated average life of 1,000 hours. Match the 230V rating to the intended supply and use only in a complete fitting approved for a 100W incandescent lamp, with suitable heat tolerance, ventilation and clearance. A matching E27 socket or ceramic holder alone does not establish suitability. If dimming, use an incandescent-rated control suitable for the lamp and supply, and check its minimum and maximum total connected load, including every lamp controlled together.
