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

Can I use this bulb with a standard 240V power supply?

No, this is a 12V low voltage bulb and must only be used with a compatible 12V transformer or power supply. Connecting it to a 240V mains supply will damage the bulb and may create a safety hazard. It is suitable for 12V lighting systems including marine, caravan, and off-grid solar applications.

Is this LED bulb dimmable?

Yes, this Candle Filament E27 12V LED bulb is fully dimmable. It is compatible with 12V dimming systems. For smooth, flicker-free dimming, use a dimmer specifically rated for 12V LED loads and check the manufacturer's compatibility list before purchasing.

What is the difference between clear and frosted glass on filament bulbs?

Clear glass showcases the filament design as a visible decorative feature, creating a warm, vintage aesthetic with visible light points. Frosted (opal) glass softly diffuses the light, hiding the filament and producing a smoother, more even glow — ideal when you want warmth without the glare of exposed filaments. This bulb features clear glass to highlight its decorative filament.
