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 Classic A 25W clear bulb dimmable?

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

Will this bulb fit my E27 light fitting?

Check that your fitting accepts a 230V 25W incandescent lamp with an E27 Edison screw cap and provides clearance for a bulb measuring 55mm in diameter and 97mm long. Confirm the fitting's permitted lamp type and maximum wattage. A matching E27 socket alone does not establish compatibility, and this bulb does not fit a B22 bayonet socket.

How can I identify this Osram Classic A clear model?

The packaging is marked Classic A, PZS230-25 and CLAS A CL 25, with a 230V 25W rating and E27/ES cap. This clear-glass incandescent bulb has a visible filament and a listed output of 240 lumens at 2700K warm white. It is not an LED replacement.
