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:

Very valuable info!!! Thank you for what you do, Jozz!

Thanks djozz. You are a legend and your work invaluable. Your efforts are greatly appreciated. Nearly every light I build I use your info to spec it up.

Who's been a busy boy ;)
Your tests are really an invaluable asset here. Cheers :beer:

Subscribed! Your reviews and tests are always thorough and informative. And i like your "not so polished" style
December 10, 2015, 12:57pm
Very nice Djozz! The signature line was huge, glad you started this, thanks for all you do here!

Djozz, improving BLF’s signal/noise ratio since 09/07/2012
And it makes it easy to point newbies to this thread for 2 purposes:
1. Gaining knowledge, without retyping it all the time.
2. To show them that testing is a requirement for pushing the boundaries of our lights.
Thanks djozz for being such a valuable, informative, and friendly part of BLF.

So I take it the 219B V1 is coming soon?
December 10, 2015, 2:25pm
Yes…thank you sir. I was just about to look for a test thread on a red xp-e2…so you helped me out there, lol.

Good catch, THE_dAY very kindly gifted me three Nichia 219B V1 4000K leds from Illumn.com, they are underway somewhere. When they are in I will test one (not to death, I will use them for a triple). I am mainly curious about the Vf compared to the old 219B and the 219C.

Sweet. Yeah Vf, and maybe you could see if lumens are still increasing at 3amps?

This is fantastic! I can’t tell you how many times I’ve referenced your data/tests to compare information for purchasing a particular light. Like most of the previous posts have said, your work is invaluable.
December 11, 2015, 2:18pm
Lets make this thread a sticky, it provides valuable info to us modders. Thank you for your hard work.
On a side note, the link to the xhp70 led seems incorrect
December 10, 2015, 3:50pm
Nice testing job! :party:
Thank you for everything, don’t stop
December 10, 2015, 3:59pm
Thanks for the nice comments :-) (was not the intention, it is all old work)
corrected the link, I hope the rest works ok
