What tool can be used to measure light reflection from different colored metal roofs?

Hi Wanda,

Thanks for the question. It can be very simple to measure light reflection. I would recommend using a light meter that you can purchase from a camera store. You can mount the light meter in a box so that ambient light does not affect it while it measures the reflected light.

I hope this helps. Thanks Jeff Grell

A camera. Fix the aperture/exposure settings, and use the brightness and color of each pixel to compare reflection.

A more thorough answer would require what exactly you're trying to measure/accomplish with the experiment... but if you are collecting light, a simple camera is often a cheap/effective tool.

Hope this helps, Burr Zimmerman


You can use a light meter commonly used in photography. Go to and search for "light meter". Here is a good overview of light meters:
