Hi,

want to introduce you to my new >500W peak power LED light:

P1030431-1.jpg


After many hours of work it is nearly finished.
Now some details:

- 20x CREE MC-E 4B K-bin and one XR-E WG Q5
- 8 MC-E with CARCLO 26,5mm plain tight optics
- 12 MC-E without optics for flood
- XR-E behind 110mm aspherical fresnel lens
- 4 5350mAh LiPo cells in 2p2s configuration
- custom made PCB holding 20 MC-E boost drivers each capable of driving upto 1,8A through each series-wired MC-E; one 4A buck driver for the single XR-E (driven to 2,2A); Atmel Mega16 µC
- 3 tumbler push-button offering 6 contacts
- each LED group individually controllable (push tumbler from below)
- 3 special functions when tumbler pushed from above: 8Hz Strobe with peak power; "far-sight" with asperical and 26,5mm group temporaraliy at full power and flood at zero; all LED at full power
- 5 temperature sensors leading to stepmise current foldback if overheating
- Mini-USB connector to charge lamp via integrated charging electronics (both 2p cells are charged with individual charging electronic to prevent imbalancing of the battery)
- XLR connector for external 10A charger and for main or 12V operation of the lamp
- 5 LED (2xgreen, orange, red, blue) for status display
- calibration mechanism for battery gauge display
- all LED soldered directly to 10mm thick copper
- wheight about 2,5kg
- total peak output (emitter output, not of-the-front) should be somewhere just over 20000 Lumen
- BRIGHT..... :devil::devil::devil::devil::devil::devil::devil::devil::devil:

Beamshots will follow in the next days. I plan to do some comparison shot with our cars xenon and halogen far light...

Ok, I did some beamshots....
All shots ISO100 F4.0 1sec

More Beamshots will follow later, it began to snow rather hard......

Will show comparison with 2x 500W halogen floodlights and some more shots at higher distance (400m) with the 110mm aspheric.

Pretty amazing light, great construction.

What is the application?

the last photo reminds me when i was looking up to the sky and got abducted by alien UFO :huh:

seriously, good job and waiting for beamshots :thumbsup:

anybody remember the runtime and lumens value of databank? :party:

You are crazy! I'm passing through Cologne tomorrow on my way to a friend in Slovakia, are you in for a meeting? I will send you a PM straight away :)

Re: Handheld 500W LED Power .... finally finished

While I'm astounded at the mere construction and array of lighting, I must ask the question; why? :thinking:
To be clear- I mean no offence and I'm not flaming. What is the usage purpose? Was this a project just for fun or do you have some specific application for this? Either way, illumination shouldn't be a problem! :twothumbs

@Sandman_Bravo and Alan_B:
Main purpose and application of the light was building it...;)

Original my intention was to use it for walking and running in the woods, but at this time I thought I could build it with a weight of less than 1,5kg.
But the more the project proceeded the LEDs I wanted to inegrate and the heavier the thing got....

I'll try it for a short run in the next days. It might work despite the 2,5kg cause I'm not the weakest....

I can summarize: I built this light as a versatile hand-light, not an EDC, that is highly usefull (runtime can be for hours if you only use a few thousand lumes ;-)) and a funlight at the same time.

The 110mm aspherical is a presision tool which offers throw nice throw capabilities for a LED powered light. It certainly can't compete with a 35W or more HID spotlight, but within the LED world it offers more throw than any other light known to me. Will take measurements in the next days, but a first quick luxmeter test over 10m distance showed more than 200000 lux/1m. But I have to measure at farer distances to get accurate value at this large lens diameter (ask Ra for the theory...).
The 26,5mm ME-Cs offer a ver usable medium beam, would also be a nice setup when used as bike light.
The 12 MC-E without optics can produce a nice amount of flood light and can serve for application where you might usually use thos 500W halogen floodlights.

You could use it during camping when powered by the 12V chahrger (not finished yet) or perhaps on my parents small boat, .....

It's just finished, so time will show what situation this portable sun will be used in......

By far the most impressive light build that I have ever seen! Absolutely AWESOME!

Re: Handheld 500W LED Power .... finally finished

I would not say the Databank is beaten. It is a total different light. It is a true fun light with one impressive type of beam: 70x XR-E behing 30mm aspherics, which results in lot more throw than my creation.
And it is an mechanical artwork, my light is mechanical functional, but you can see that it is made by an electronics engineer with no professional mechanical equipment nor skills.

Like I wrote before: I tried to combine useful and fun light, and I thing I managed to do so. Main thing I'm not satisfied with is the 2,5kg weight.

But regarding total output, it might be true that for half a minute I can beat the databank :)

Re: Handheld 500W LED Power .... finally finished

you could have used heatpipes and connect them to cpu cooler. If a cpu cooler can cool down a cpu with more than 150W then you need only 4 of them but then have to use fans.....
I think 2.5kg is a good weight for passive heatsinking.
