14,000 CP from an LED?

[notos&w]

does anyone know if this is right?

its hard for me to believe. either its wrong or ive got no idea how much a candlepower is.

I think it should be 14000 mcd, not 14000 cd.
I dont think there's a dry cell torch available with that kind of power unless its an extremely narrow laser-like beam!

I agree, someone slipped a decimal point or forgot the Mcd which is a factor of 1000

When LEDs first came out, they were all rated in Mcd, until Stanley broke the 1000mcd barrier with the H1K and since then, most all "bright" LEDs are now rated in cd

I think it should be mcd not Mcd as Mcd would be megacandela. (100000 candela) A 14000 Mcd torch would be about the size of a bus and its light would be visible from the moon!

Hey, we could call it the ARC BFL!

I think it's quite a oommon mistake for people to get thier mega's and milli's mixed up. I've heard of engineers getting it wrong causing catastrophic mathematical errors!
The difference is a factor of a billion...
1 Mcd = 1000kcd = 1000000 cd = 1000000000 mcd!

<font size="2" face="Verdana, Arial">Well not on 2 123s for 25 hours...I get an initial peak of about 13,000 from my UKE SL6 incandescent with SIX C CELLS -- and it runs down from that and poops out in 3 hours or so.

That's about as much as I've seen from an alkaline torch. The SL6 is rated at 200 lumens. The larger D8 is only 245 lumens!!!

I'm sure that one could achieve a brightness greater than 14,000 CANDLEPOWER from a single LED if a 5-watt Luxeon Star was focused into an extremely tight beam using advanced optics.......
