This thread is definitely worth a bump.
Can a thread here be “stickied”??
Yes, but only Mr. Admin can do it.
If you want something stickied, you can ask him.
EDIT:
This thread has already been stickied.
^ Good to hear it. It has a very good explanation about the relativity of throw, spill, brightness, and temperature. And yeah, those zoomies are novelties for the most part. 
thanks for taking the time to lay this all out for me Mr Newbie. I will go over it a few times in the next while. Thanks
Good article, you put a lot of work into this! Its very informative, thanksfully.

This is the flashlight bible in the making...
that bible has been written several times…

Okay, evenif it was only bumped by a spambot, I’d hate if this got buried again. So… Bump.
BUMP - Very well done. Wish I found this 2 months ago when I first started researching flashlights!
Can always add:
It must list “tactical” in its description. If it’s not “tactical”, it’s garbage.
But these is almost always black. So don’t that make em’ almost all
ways...tactical? 
I kept getting confused and mixed up between throw and candela numbers so did some research and wrote up what I found out. Also added some more explanation and a quick reference:
Hopefully this will make it easy to compare 2 lights when one’s specs says 100kcd and another says 600m.
Here’s some of the numbers to save you a click:
- 500cd = 45m
- 1kcd = 63m
- 5kcd =141m
- 10kcd = 200m
- 20kcd = 282m
- 50kcd = 447m
- 100kcd = 632m
- 200kcd =894m
- 500kcd = 1,414m

hm
interesting, thanx!
√(cd*4) also gives you FL1 throw in meters from candela numbers.
(Throw^2)/4 gives candela from FL1 throw.
wow, i`m glad no less no meet such a positive feedback.
Awsome!!
Thanks for your hard work, really professional.
and BTW if anyone would like to try Acebeam, could kindly tell me, I could offer you guys 10% off for Acebeam’s flashlight.

Hey guys. I am new here, just was looking for a flashlight and stumble across your forum. Need advice as I am a real newbie and don’t really know anything about the flashlights
I wanna find smth good for my husband, he riding a bike all the time and sometimes at night, so I thought a new powerful flashlight would be a great idea for a present. I found one, but I don’t even know if it’s good….you know, I see only that it’s pretty, but what about the technical side?
