Is it possible to convert a lights output candlepower or lumens into actual total output wattage (solar energy)?
I'm trying to determine just how much actual light energy in watts is being released by these 1, 2, 3, 5, and 10 million candlepower spotlights (or similar devices) on the market. I'm aiming for a pump device capable of driving a powerful non-coherent emission through a system of focused lens's. I'd like to do a project for college which aims towards battery derived energy, a wood-burning demonstration, and then demonstrate how pure daylight emission from the sun has a much higher potential when utilized properly (in theory, and relative to what is obtained easily for "free" in a sense).
My goal is high-output light focused to an extremely small point which then slides across the wood via a channel once it's in focus to demonstrate it's potential to smoke an object.
