# Candel Power

Hi all,

I have just bought a 1.7 Million candel power rechargeable torch.

What exactly does candel power mean in real money?

Can it be compaired with say a car headlight, the sun or what?

Is there a conversion to watts (like 100W house lamp)?

The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 x 1012 hertz and that has a radiant intensity in that direction of 1/683 watt per steradian.

Shine it in your eyes, then you can quickly find out how bright 1.7 million candle power is. Or if you don't feel like burning your eyes you can just shine it in a field.

I was just wonderingif ther is something we could compare it to, such as car headlights or something?

I think about candle light, for example like a car headlight, the light is measure by counting the candles that may seems the car headlight and the candles would be the same regarding the light they are producing.... like the headlight measured as 10 candle light then, the car headlight is same as 10 candles... that is from my observation...

Candle power is a unit to measure the light intensity of the Light sourse.

"Candle power" is now replaced by the candela

**candlepower is equal to about 0.981 candela. so is ~ 1 candela

Average candle power = totel Luminus Flux / [4x3.14]

electric glow-lamps of low intensity nominally of 8 candle-power or less

grouping a bunch of candles together wouldn't create an intense light would it? If you put 1,000 candles together, you would have the same amount of light in a wider area. That's what I think anyway, which is why candle power is hard for me to picture.

But... is candela the same thing as "candle power?" I think the original poster is talking about a different unit. Maybe something the company made up to sell the torch
