# Thread: Output of the Sun: How many Lumens?

1. ## Output of the Sun: How many Lumens?

Hey guys,

My roomate and I, both enlightened cpf users and flashlight enthusiests, were just discussing the output of the sun. We both have no idea where to begin with this kind of quiestion.

I was wondering if anybody else had any thoughts on this subject. How many lumens does the sun produce?

Also, obviously the sun has way more spill then throw, but i would like to hear your thoughts on possible lux readings as well.

6,840,000,000,000,000,000,000,000,000 lumens.

BZZZT WRONG!! 6,840,000,000,000,000,000,000,000,001!!

4. ## Re: Output of the Sun: How many Lumens?

Have a look at Wikipedia: ~3.75×10^28 lm

5. ## Re: Output of the Sun: How many Lumens?

the sun is just a maglite lol compared to these "look at size difference after sun"

Oh, yeah? The Sun is incandescent!! Take that, led lovers!

We can't be sure....we'll have to put it in a calibrated integrating sphere to determine the output with any kind of accuracy.....

I think I have one in my garage...

I'll take it.

9. ## Re: Output of the Sun: How many Lumens?

Ill take any light that burns that long and that bright

11. ## Re: Output of the Sun: How many Lumens?

what size reflector will i need? and is it regulated?

No audio.. But that made me feel just a little smaller.

dont know about a reflector but is sure is regulated.... right up to the END!

14. ## Re: Output of the Sun: How many Lumens?

Pretty good runtime, but it needs a clicky. Nice color temp at 5700K too, very close to err... it self.

15. ## Re: Output of the Sun: How many Lumens?

i wonder if heat will be an issue?

16. ## Re: Output of the Sun: How many Lumens?

Don't be soft DM51 take "LBV 1806-20" instead, it's up to 40 million times(!) brighter than the Sun, that might even satisfy some of the HID guys

More like HID,

those Kelivn temperatures are way to high for an Incandescent.

No no no... , so far I know, the sun is manufactured by Lumileds

In that case it will not be delivered until 2010, starting with very low bins.

Luckily there is moon mode available, too.

Runtime? Bulb life? USPS Interstellar Priority delivery charge? Beamshots? Is LBV a reliable company to deal with? Is #1806-21 available as well? And more importantly, what the hell was it that went wrong with the emitter in #1806-01? Come on now, you know we need these details.

23. ## Re: Output of the Sun: How many Lumens?

I think I'm going to hold out for the upcoming DealExtreme version, Sun 2.0. It is suppose to have a Cree, run at only 750,000 degrees instead of 1.5 million degrees and it is bored out for a 18670 battery. There is a warning label on it; something about not shining it in your eyes, but I'll just scrape it off like I did with my 500mW green, non-IR filtered laser pointer.

24. ## Re: Output of the Sun: How many Lumens?

No thank you. I can't get past the fact that the optics are so inefficient: more than 99.999998% of the lumens just fly off into space, and of those, less than half actually make it to the ground! Visual light transmission on the thing is terrible, half the time it looks completely "cloudy"! If they put a reflector on they could really drive up the lux readings but as it is I'm not impressed. Don't even get me started on the tint -- I absolutely hate those 6000k cool white lights, they lights make everything look blue and nasty , call me again when they make one in warm white.

25. ## Re: Output of the Sun: How many Lumens?

Why not wait for the Super-Nova version of the Sun? It is expected to be much brighter. And excellent at burning newspaper, ants, and most anything else. Would it be consider a one-time-use only device?

26. ## Re: Output of the Sun: How many Lumens?

There are many little annoying, blotchy artifacts present in the Sun's beam however. They have names like, "Earth".

27. ## Re: Output of the Sun: How many Lumens?

I don't know if you saw the latest Surefire catalog but the Hydrogen Turbohead looks like a winner. It looks like it runs really HOT so don't forget your oven mitts.

You might have to upgrade to a metal reflector and glass borofloat lens

I'm not sure what size you would need... I would assume a turbo head would be the best for collecting all that throw.

29. ## Re: Output of the Sun: How many Lumens?

I wonder what the output would be on "burst".

30. ## Re: Output of the Sun: How many Lumens?

The sun isn't incan, it's fusion-powered. It actually has a pretty weird runtime plot - It takes a long time to start up, then kicks into normal pretty suddenly, then there's a big but short-lived increase near the end, then it slowly dims down.

Terrible UI, though - no variable brightness, and you can't even turn it off! It just runs until its power source is gone.
