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

What does CRI 100 mean?

CRI (Colour Rendering Index) measures how accurately a light source renders colours compared to natural sunlight. A CRI of 100 is the maximum possible score, meaning this bulb reproduces colours with perfect accuracy — ideal for photography, retail display, art galleries, and any colour-critical application.

Why does this bulb have a UV filter?

The built-in UV filter blocks ultraviolet radiation from the halogen element, protecting sensitive materials, artworks, fabrics, and merchandise from UV-related fading and degradation. This makes it suitable for use in galleries, museums, and retail display environments.

Is this bulb dimmable?

Yes, this Osram JDD Halolux Ceram halogen bulb is fully dimmable and compatible with standard halogen dimmer switches.
