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.
12V 10W Oven Capsule
G4 halogen lamp marked 300°C for a matching shielded oven lamp assembly.
140lm · 2800K
Warm white light with Ra 100 colour rendering and a 2,000-hour rated life.
⚠️ 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.
This OSRAM HALOSTAR Oven halogen capsule has a G4 bi-pin base and is marked 12V 10W 300°C. It produces 140 lumens of 2800K warm white light with Ra 100 colour rendering and immediate full brightness.
Use it only in a shielded oven lamp assembly specified for this replacement lamp. Match the appliance model, 12V supply, G4 socket, 10W load and 10mm diameter × 33mm length, retaining the required lamp cover and seals. The 300°C marking does not establish compatibility with every oven or cleaning cycle. Follow the appliance manufacturer's replacement and self-cleaning instructions, keep the lamp switched off during high-temperature self-cleaning, and use a qualified repairer for internal electrical work.
