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.

Frequently Asked Questions

Is this Osram 100W frosted bulb dimmable?

Yes. This model is listed as dimmable. Use a dimmer compatible with incandescent lamps and check that its voltage and load ratings suit the 100W bulb and the total connected load.

Will this bulb fit my E27 light fitting?

Check that your fitting accepts a 230V 100W incandescent lamp with an E27 Edison screw cap and has clearance for a bulb measuring 60mm in diameter and 105mm long. A matching E27 socket alone does not establish electrical or dimensional compatibility.

What distinguishes this frosted Osram Classic A bulb?

Its frosted glass softens the appearance of the light compared with a clear bulb. This is a 100W incandescent lamp, not an LED replacement, with 2700K warm white light, a rated output of 1340 lumens and a rated average life of 1,000 hours.
