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 pack contains two clear twin-filament incandescent bulbs with bayonet caps. The packaging identifies LT039W17, 12V and 32/4CP, with stop/tail and indicator lamp applications. CP denotes candlepower, not watts: the 32/4CP marking must not be rewritten as 32/4W or assumed equivalent to another bulb's 21/5W rating.

Frequently Asked Questions

Are these twin-filament bulbs dimmable?

Dimmability and compatibility with PWM, bulb-failure monitoring or aftermarket controllers are not confirmed. Twin filaments do not establish universal dimmer compatibility. Use only the exact vehicle manufacturer's approved lamp and control arrangement; the dimming field remains blank.

Will these 12V bayonet bulbs fit my stop/tail or indicator lamps?

Check the exact vehicle and lamp assembly's approved bulb, 12V supply, electrical load, contact arrangement, bayonet pin positions and available clearance. The packaging lists stop/tail and indicator applications, but not universal compatibility. Exact cap code, dimensions and wattage are unconfirmed. Do not substitute solely because the cap looks similar or the bulb has two filaments. A compatible vehicle circuit supplies 12V; these are not for direct 240V mains or 24V vehicle circuits.

What does 32/4CP mean, and how many bulbs are included?

The photographed pack contains two bulbs and is marked 12V 32/4CP. CP denotes candlepower, a light-intensity rating, not electrical watts or total lumens. Do not convert it to 32/4W or assume the bulbs are 21/5W. Wattage and combined electrical load remain unknown, so the wattage and lumen fields are left blank. The Australian-owned wording does not establish country of manufacture.
