Does anybody have a handle on candela versus lumens?
"Out there" I see the brightest defense flashlights rated at 150 or 200 lumens.
Today I saw a defense flashlight rated at 12,000MCD that hurt my eyes.
According to converting calculators I have found, 150 lumens converts to about 6.3 million MCD - well over 500 times as bright as the above flashlight.
Working the ...
Well, this is one of those things that there is no easy conversion factor. The candlepower is almost not used anymore, and it did refer to actual candles. I will give you a rough comparison. My Streamlight Ultra Stinger is rated both ways by Streamlight. It is rated at 75000 candlepower and at 295 lumen's. Now here is the problem. You cannot use this as a direct conversion because lumen's is ...

From my example I would say the 12000 MCD is the brightest by far. I read 12000 MCD as 12000 X 10 to the 6 candle power.....and that's a big number.
Hm. Something I read said MCD means millicandela and/or megacandela. I guess some disciplines use milli to mean divided by 1000 while others use it to mean multiplied by 1000. Confusing....

And it would be odd if the 12000 MCD was the brightest of the two. It sells for $25,
OK, I am probably wrong on the units. I read that the capital M was meg and the little m was milli, anyway you are not going to beat 150 lumen's for $25.

Candlepower is the measurement of how bright it is at one spot (think spotlight or laser pointer).
Lumens is total light output.
If you've ever used SureFire or any lights like that, a 60 lumen two cell vs a 500 lumen 6 cell (SureFire M6 for example) both have the same brightness but the M6 puts out much more light.
There's really no way to compare CP to Lumens. And even then, ...

Can't agree on that. I have the SureFire G2 (6v) that originally had the 60 lumen incandescent lamp. That is not the same lamp that the M6 (18V) uses....

I like to use the "hose" analogy.
A hose emits water, a flashlight emits photons.
If you have a hose it has a maximum capacity of water (Gallons per minute) that it can emit. HOW it emits that water is ...

Different ways indeed. I doubt half of them know what their claims mean.
Another thing. I'm attempting to compare two lights, one rated in MCD and one rated in lumens. Bad enough in the first place. Now...

I go back to my Streamlight. 75000 candle power is about 295 lumen's. So that's about .004 lumen's per 1 candle power.
The fact is that 150 lumen's is pretty good. The old standard for years was a 3 "D" Maglight at about 45 lumen's,
I realize as someone said again, that candela and lumens are apples and oranges - my OP even made the ...

As you can see, I said pretty much that in my OP. But such technicalities simply aren't helpful when the manufacturers use multiple non-standard descriptions. I think that Madmag's .004 rule, while not ...
I agree that the new LEDs have come a long way in terms of output, throw and battery life.
I went from a Surefire 6P to a cheapy NOMA 140 lumen light that runs on 3 AAAs.
TBS the flashlight under the seat of each of my trucks is an old school 3 D cell Maglight. It's hard to change a BGs attitude with a small, plastic tactical light
I looked up my $25 12,000 MCD flashlight (A Nebo) on the internet. Oddly the first thing I found was a smaller, cheaper one (still Nebo), a $16 96,000 MCD flashlight, according to the description. HUH?! I'm even more convinced that the makers don't know what they are talking about.
JimL, I think $25 range will get you a decent LED flashlight, but I think if you stick with buying at Target, Sears, Wal-Mart, etc you will find their lights are listed in lumens and are usually accurate about brightness.

A hose emits water, a flashlight emits photons. If you have a hose it has a maximum capacity of water (Gallons per minute) that it can emit. HOW it emits that water is greatly dependent on the shape and size of the nozzle. A very large nozzle with a lot of...
