Efficiency of 12V Lights

In layman's English, the overall output of a light is measured in lumens. This is different from luminance, which is the perceived brightness of light falling on a surface illuminated by a lamp. This is measured in lux. So lumens is the best indication of how much a light will light up your room. The efficiency of a light is usually measured as lumens per watt.

We produced a chart of some of our popular 12V lights listing their lumen output and efficiency as given to us by the manufacturers.

As pointed out in other articles in our FAQ Lighting section, the perceived brightness of a light is also influenced by other factors such as the colour of the walls, use of reflectors etc.

Cheers from Dave and all the RPC crew.

Dave Lambert (Director)
