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.

⚠️ Important: These are 12V automotive bulbs for a compatible 12V vehicle electrical system. Do not connect them directly to 240V mains or a 24V vehicle circuit. The compatible vehicle circuit supplies 12V; a separate household transformer is not normally part of installation.

This LION retail pack contains two clear double-ended festoon incandescent bulbs. The supplied packaging identifies LT039W13, 12V, 10W and interior/stop lamp applications. Each bulb is rated 10W, giving a combined rated load of 20W when both operate. Match the exact vehicle and lamp assembly's approved voltage, wattage, bulb length, end-cap profile, holder spacing and clearance.

Frequently Asked Questions

Are these 10W festoon bulbs dimmable or compatible with electronic interior-light controls?

Dimmability and compatibility with courtesy-light fading, PWM, bulb-failure monitoring or aftermarket controls are not confirmed. Use only the vehicle manufacturer's approved bulb and lighting-control arrangement. Incandescent construction alone does not establish compatibility with every control; the dimming field remains blank.

Will these festoon bulbs fit my vehicle's interior or stop lamps?

Match the exact vehicle and lamp assembly's approved 12V supply, 10W load, overall bulb length, end-cap profile, holder spacing and clearance. The packaging lists interior/stop applications, not universal fit. Length and standardized cap code are unconfirmed, so do not select solely by appearance. Normal installation uses the compatible vehicle's 12V circuit rather than a separate household transformer. Do not connect directly to 240V mains or a 24V vehicle circuit.

How many bulbs are supplied, and can I substitute the 5W or 18W festoon versions?

The photographed LT039W13 pack contains two clear 12V 10W festoon bulbs, for a combined rated 20W when both operate. Do not assume the 5W, 10W and 18W versions have interchangeable dimensions, loads or applications. Use the exact approved replacement rating and holder dimensions. The Australian-owned wording on the card does not establish country of manufacture.
