Handheld 500W LED Power .... finally finished (Beamshots added)

[Holzleim]

I added beamshots in the first post....

[JetskiMark]

Thanks for the beamshots.

That is an incredible creation.

Only a true flashaholic would consider that to be a reasonable light to take on a walk or a run.

Gotta love CPF.

[jirik_cz]

Wow that's really bright !

[DM51]

Astounding beamshots - some of the best I've seen. They give a complete idea of the capabilities of this superb light. As JetskiMark says, a great creation!

[N10]

everything everybody said...astonishing creation!!...&& cool beamshots!

[glockbob]

Very good beamshots, gives us a really good comparison on how bright this creation really is.

How many hours did it take you to create this monster?

[Holzleim]

Thanks for the approving words!

I didn't count the hours, but most time consumed the mechanical work due to the fact that I don't have any professional mechanical equipment. So I had to improvise many times, for example I did some milling with a cheap simple drill machine stand (with many scratches to my hands...)

The electronic part is more the kind of work I'm used to, but even this took much time because I had to deal with more than 500W (>70A at 7V...).

For the software I could re-use a lot I already implemented in my two previously made lights.

I think I started with thinking about the concept of this light in July 2008...

[toby_pra]

The beamshots are incredible...WOW!!!

[DM51]

I've added this to The BIG Lights thread.

[Packesel]

Turn off that light! Last night I couldn 't leave my house without my sunglasses - in the middle of the night. I live about 15 km away in Leverkusen (Germany).
The german word for flashlight is "Taschenlampe" which means "pocket light". But this is something like a suitcase light.

Viele Grüße (regards)

@DM51:
That's really a great honor for my to have my light mentioned between all these legends. So now there is slightly more LED presence in this area, thanks a lot!!!

@Packesel:
I pointed my light direction Koblenz, so you must have seen some kind of diffuse reflections
And that large your pocket doesn't have to be: Outline dimensions are about 18cm x 14cm x 8cm. Not really an EDC, but much smaller that a Thor or similar.
But you are right, I do not call it "Taschenlampe" but "Handstrahler".

Holzleim,

WOW, great light!

Beautiful work and a very fun design.



Cheers

Du verrückter Hund! hammergeile Kiste.

Was für ne Wahnsinnskonstruktion echt geil. Bin echt baff .....so was in der Art hab ich schon lange mal sehen und baun wollen. Einfach nur toll

[csshih]

That's obscene.
portable extended use flashbang?

I am extremely impressed with your work, and I love that soldering job.. with an actual iron.

[J.D.]

kann den Lobeshymnen nur zustimmen - wasn geiles Teil

[Sabre]

Besonders ausgezeichnet! Wie schwer ist es?

[Holzleim]

Weight is about 2,5kg.

Portable flashbang is good......

[rantanplan]

... unbelievable.

Reminds me of "Opas Flakscheinwerfer"

[csshih]

.......aaaanndd the classic CPF question.

does it come with a pocket clip?

[Holzleim]

It comes with a neck chain....

[missionaryman]

I think you just cured me from being cured from flashaholism

[Holzleim]

Just want to mention another application for my light:
Usage as powerful photo light. In the photo below I used the flood at about 10-20W. Could have been some more next time, there is enough room left until max power....

My daughter playing in the bathtub (both camera and lamp kept dry ):


Forgot to mention: ISO100, F3.3, 1/100s, White Balance Daylight, no Flash

[deusexaethera]

I think your next project needs to be a lightsaber. I'm not sure how else you can top a portable stadium light.

[toby_pra]

Again, this is an awesome work!

For what you will use it?

You just did it!!! You justified the need for a second one. Think of the nice shadows you will get with a second light @ a different angle and @ 50% power of the main light.

[Holzleim]

@deusexeathera: Next light will be either a really small light (samller than my David) or a HID monster (HID > 500W, need custom designed ballast operating from 2s-4s LiPo cells).

@toby_pra:
Will use it for:
- running in the woods
- barbecue in the dark
- light on a small sail boat
- photo light
- video light
- changing tires in the dark
- .........
- FUN!!!!

@CampingLED:
If I build a second big light, it certainly must have more power than the one previously built

[deusexaethera]

You just did it!!! You justified the need for a second one. Think of the nice shadows you will get with a second light @ a different angle and @ 50% power of the main light.

But anyone who poses for more than a few seconds would catch fire. That would throw the shadows all off, not to mention preclude a second sitting.

[deusexaethera]

But if you build an "HID monster", then you really are building a stadium light. That's already been done. You need to do something different. Like learn how to channel the Force, for instance.

Holzleim, can I order two please. I have this "burning" desire to photograph my neighbour's cats that are catching the wild birds in my garden.

[Holzleim]

By the way, you mentioned "burning"......
A piece of paper being burned by the MC-E's intensive light output. Note that it is pure visible light that burns the paper. The LEDs do not emit any infrared light like an incan or HID.
