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.

Narrow 8° Spot Beam

Aluminium reflector directs light for focused accent illumination.

12V BA15d Halogen

20W lamp with UV-STOP, 150-lumen output and 3000K warm white light.

⚠️ 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.

The Osram Halospot 70 halogen light bulb uses an aluminium reflector to produce a narrow 8° spot beam for focused accent lighting. Its 20W halogen source delivers 150 lumens of 3000K warm white light with CRI 100 for natural colour rendering.

This lamp has a BA15d double-contact bayonet base, a 70.5mm diameter and a 50mm length. Match the equipment specification to its 12V supply, 20W load, base and dimensions, and follow the fitting's ventilation and heat-clearance requirements.

Frequently Asked Questions

What power supply does this lamp require?

Use a compatible 12V transformer or power supply. Each lamp draws 20W; keep the combined lamp load within the supply's minimum and maximum ratings. Do not connect the lamp directly to 240V mains. Before using a dimmer, check the lamp and supply manufacturer's dimming specifications and the control's load ratings.

Will this replace any BA15d bulb?

No. Match the equipment specification to the 12V supply, 20W rating, BA15d double-contact bayonet base, 70.5mm diameter and 50mm length. The 8° beam must also match the required lighting pattern. Follow the fitting's ventilation and heat-clearance requirements.

What makes the 8° beam different from a flood lamp?

The narrow 8° spot beam concentrates light into a smaller area than a wider flood beam. This Halospot 70 uses an aluminium reflector and produces 150 lumens of 3000K warm white light with CRI 100. It is a halogen lamp, not an LED.
