Colour Temperature
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
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.
⚠️ Important: This is a 12V low voltage bulb and requires a compatible 12V transformer or power supply. It will not work with standard 240V mains voltage.
The OSRAM 6418 C5W is a clear incandescent festoon bulb with metal contacts at both ends and a visible central filament. It is intended for compatible automotive lamp holders and is rated 12V and 5W with SV8.5-8 end caps.
The overall length is 36mm. Match the original bulb's designation, end-cap shape, length, voltage and wattage before purchasing; a similar-looking festoon bulb is not automatically interchangeable. Typical applications include number plate, position, interior and reading lights, but suitability depends on the vehicle and lamp assembly. For vehicle use, the compatible 12V electrical circuit provides the supply; a separate mains transformer is not normally part of the vehicle installation.
