Road Cycling - 1 million candle power is equivalent to how many watts?

I found a $15 portable handlight that puts out 1 million candle power. If that is equivalent to at least 10 watts then I am getting it.

I'm not certain the two are interchangeable as a unit of measurement. Candlepower is an expression of Lumens (1,000,000 Candlepower=12,566,370 Lumens), whereas 'watts' are a measurement of resistance.

Yep, X-watts to a different filament or gas will produce different Lumens.
Like xenon gas lamp compared to an incandescent vacuum bulb.

This is probably correct " (1,000,000 Candlepower=12,566,370 Lumens).

I think you will find that the light in question requires much more than 10 watts in order to generate a million candlepower of light.

Let me rephrase the question. Is 1 million candle power as bright as a 20w MR11 bulb?
I found a $15 rechargeable handheld spotlight that puts out 1 million candle power. If I can "macgyver" the light to the handlebars it would make a great headlight.

i have a million Candela power spotlight for night fishing. that sucker is crazy bright. if you had that on a bike you would light up the entire woods, or at least blind all the animals.

Depends on the type of light but I think basic halogen is a good standard to compair though xenon halogens are more efficiant. A 35 watt hand held halogen spot light is about one million candle power this would be, very roughly, a 25watt LED or 20 watt HID.
On a six volt system 35 watts will draw about 6 amps(6v*6a=36watts) so you will need 6 amp-hours of battery per hour of run time.

Depending on the type of battery you should leave a large reserve because deeply draining a battery, say a lead-acid(cheap kind), can reduce its life very rapidly, the same goes for not keeping it topped up for long periods.
A nicad should be charged absolutely full then drained close to dead then charged full again when its new be cause nicads have memory and will not hold a large charge if it was short cycled when new.
Ni-mh don't have a memory as far as I know and can be deep cycled and rapid charged, basicaly are the best, lightest, rechargeable thing going but they cost some big coin.

Yeah I would think that less than half of that would be more then sufficient, this does raise the question of why do all the company advertise watts and not lumen. I feel like that would be a lot more telling especially since all the LED company try to say how bright they are.
