Great job Joe! All the charts made perfect sense to me. I couldn't believe how low the output of my XM 15 k's is. I will be trying different bulbs when it's time to replace mine. As long as they give me the same coloration, with the same power usage, I might as well pick bulbs that turn that power into usable light. Great job, and thank you for all the time you spent on it!
