With halogen youve got a couple of options.
Halogen temperature color. For lamps with a color temperature of over 5000K the reference is natural daylight which also has a CRI of 100. High voltage tungsten halogen lamps have a luminous efficacy of about 22 lmW. Dont waste your money on them.
Halogen bulbs are incandescent bulbs and work with a glowing tungsten filament with some special design features to extend bulb life. Yellowish light with tint of orange. As we go higher on the Kelvin scale we will progress to yellow lights white light and blue lights.
They are shown for reference but would not be part of a true Color Temperature chart for reasons described below. The lower the K to more red the color. Quick web search showed that in Britain many other countries follow the same standard halogens with a colour temperature over 4200K are not street legal.
Incandescent and Halogen lights are found around 2500K 3000K. To make it more clear the color temperature of the candlelight is about 2000K and Halogen lights are around 2800K. Homey light slightly brighter than warm white.
It is generally accepted that outputs below 5000K Kelvins are warm colors while outputs higher than that are. Common luminous efficacy is about 30 lmW and color temperature for studio lighting of 3200 degrees Kelvin. At the lower end of the scale from 2000K to 3000K the light produced is called warm white and ranges from orange to yellow-white in appearance.
Halogen bulb- A cooler bluer yellow tint with a temperature of 3000 K. With a colour temperature of 5000K however this bulb is only suitable for off-road use. Standard incandescent bulb Yellowish tint with a temperature of 2700 K.
