Does anyone know if there is an affordable lightmeter w/ a usb or serial interface that you can hook up to your PC and capture the readings on it? I'm thinking of a dedicated station or laptop that could run next to the lightmeter and capture the output and runtime length for a flashlight. That would be a great tool to help compare flashlight to flashlight.
Anyone seen something that could fit this bill?
