Light Bulb Fittings

The light bulb fitting is the part of the bulb that connects it to the socket of a light fixture.

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.

The OSRAM Halolux Ceram 64401 is a clear E27 halogen light bulb rated 230V and 100W. Its own packaging confirms 1800lm output, 2900K Warm White light and Ra 100 colour rendering. The attached OSRAM datasheet identifies order reference 64401 ECO 100W and confirms 32mm diameter, 105mm overall length and a T30 outer bulb.

Use only in a complete fitting approved for a 100W halogen lamp and the intended supply, with suitable heat tolerance, ventilation and clearance. The carton carries a greater-than-200°C heat warning, not an appliance temperature rating. No low-voltage transformer is required; a matching E27 cap alone does not establish suitability. Dimming requires a compatible halogen control within its minimum and maximum total connected load, without a guarantee of universal compatibility or flicker-free full-range operation. Ra 100 is a colour-rendering rating, not a promise of perfect reproduction of every colour. The UV filter does not mean zero UV or guaranteed protection against fading. Its 2,000-hour average life is not guaranteed; the carton's two-year comparison assumes 2.7 hours per day. Existing Germany origin is retained but not independently confirmed by these reviewed sources.

Frequently Asked Questions

Can I dim this 100W Halolux Ceram bulb?

The packaging and model-specific OSRAM datasheet confirm dimmability. Use a compatible halogen dimmer within its minimum and maximum total connected load. Each lamp contributes 100W, so add all connected lamps and check the control and fitting limits. No low-voltage transformer is required. Universal compatibility or flicker-free full-range operation is not guaranteed.

Will this E27 halogen bulb fit my lamp?

Match its 230V, 100W halogen rating and E27 cap to the complete fitting instructions. The model-specific datasheet confirms 32mm diameter and 105mm overall length. Check heat tolerance, ventilation, clearance and any required protective cover; matching caps or ceramic holders alone are insufficient. The greater-than-200°C packaging warning is not approval for ovens or appliances. Any operating position remains subject to fitting restrictions. Switch off and allow the bulb to cool before handling.

What do Ra 100 and the UV filter mean for displays?

The carton and model-specific datasheet confirm Ra 100 and a UV filter. Ra 100 is the general colour-rendering index relative to its reference illuminant, not a guarantee of perfect colour accuracy for every application. A UV filter does not mean zero UV or guaranteed protection against fading; assess conservation-sensitive uses separately. This is a 100W halogen lamp, not an LED. The 2,000-hour average life is not guaranteed, and the carton's two-year comparison assumes 2.7 hours of use per day.
