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.

24° Directional Beam

Aluminium AR111 reflector with 1200-lumen output.

3000K • CRI 100

Warm white halogen light with a UV filter and 4,000-hour rated life.

⚠️ Important: This is a 12V low voltage bulb and requires a compatible 12V transformer or power supply. It will not work with standard 240V mains voltage.

This Osram Halospot AR111 halogen light bulb combines an aluminium reflector with a 24° beam for directional illumination. Its 100W lamp produces 1200 lumens of 3000K warm white light with CRI 100 colour rendering and a UV filter.

The G53 base uses two terminals for connection in a matching 12V fitting. The lamp measures 111mm in diameter and 61mm in overall length, with a 4,000-hour rated average life. Match the supply capacity, connector, fitting's 100W halogen rating and available space, and follow the fitting manufacturer's ventilation and heat-clearance requirements. Switch off power and let the lamp cool before replacement.

Frequently Asked Questions

Can this 100W Halospot lamp be dimmed?

Yes. Use a compatible halogen dimmer and a dimmable 12V transformer or power supply. Each lamp draws 100W; check the minimum and maximum load ratings of both the supply and dimmer for the total connected load.

Will this fit any AR111 or two-terminal light fitting?

No. Match the G53 connection, 12V supply, 100W halogen rating and 111mm diameter by 61mm length to the fitting's requirements. Follow its ventilation and heat-clearance instructions. Never connect this lamp directly to 240V mains.

What light does the 24° reflector produce?

The aluminium reflector directs 1200 lumens of 3000K warm white halogen light into a 24° beam. The lamp has CRI 100 colour rendering and a UV filter. The filter does not eliminate fading risks for light-sensitive objects.
