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

Is this LED bulb dimmable?

Yes, this T30 Filament LED bulb is fully dimmable and compatible with standard leading-edge and trailing-edge dimmer switches rated for LED loads. For smooth, flicker-free dimming, use a dimmer designed for low-wattage LED bulbs and check the manufacturer's compatibility list before purchasing.

What fixtures and applications suit this T30 tubular bulb?

This 300mm T30 tubular filament bulb is designed for applications where the bulb itself is a design feature. It suits statement pendant lights, exposed bulb fixtures, wall sconces, architectural lighting, and creative installations in restaurants, bars, hotels, and residential spaces. Its extra-long profile makes it ideal for linear pendant arrays and feature lighting.

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 — ideal for statement lighting where the bulb is part of the design. Frosted (opal) glass softly diffuses the light, hiding the filament and producing a smoother, more even glow. This T30 bulb features clear glass to maximise its dramatic visual impact.
