I start this thread, or actually just a post, to make everything that I tested the last few years and posted on BLF, a bit more accessable (yesterday I tried to put everything in my sig-line but that just looks ugly, so now the sig-line just contains a link to this post). If I do more tests in the future, I will add links to them in this post.
As a general disclaimer, the minimum that I try to achieve in my tests is a good impression of what is going on with a led, spring, or whatever it is that I tested, which may be helpful in modding a flashlight. In some cases I dare claim that what I measure is a good approximation of the reality. In no test I claim that my results are the exact truth, as an amateur I make no use of certified or officially calibrated equipment, and the test set-ups are usually (though well thought-over) home-made contraptions. I do always try to pay attention to possible shortcomings of the used method.
Here are the links:
