Scratch-built 7x C8 reflector high-output thrower

That’s an interesting idea, thanks.

OK, I got some beamshots. The location is a lake. There are small docks with benches distributed along the shore. The distance between the two I’ve chosen is about 500m. You can just make out the dock in the beamshots. Unfortunately it cooled down today and tonight so there is a bit of moisture in the air.

This is what one of the docks looks like.

I have beamshots of 4 of my throwy lights, widely distributed in candela. All photos have the same exposure settings and, at least on my computer, they look roughly what it looked like in real life.

First is an Eagle Eye X6 with dedomed XPL V6 1A with Ledil Iris TIR. It has about 95Kcd.

Next is my fresnel lens Convoy C8 conversion with dedomed XPG2. It has around 166Kcd.

Next is a larger fresnel lens light (60mm active diameter) with dedomed XPG2. It has around 310Kcd.

Next is the monster 7x C8 high output thrower with ~740Kcd.

It puts a lot of light downrange and really is in a separate league compared to my other lights.

Impressive! :smiley:

Impessive? I’ll up that one and go super impressive. :slight_smile:

Lux that high with a hotspot that big is just awesome :open_mouth: Great job :beer:

That’s one heck of a thrower! :beer:

Whoa! Heck yea, that’ll do it!

Well said. This is what l was thinking but couldn’t put it in words. :beer:

nice!
super? no hyper impressive!
dang what wall of light, no more a train of light

Not nearly bright enough for me but I guess it would be “okay” for walking the dog or something.

:wink:

I’ve been thinking about my next very high output light and decided upgrading the emitters in this 7xC8 light is a good route. I will replace the dedomed XPLs with sliced XHP50.2s. With 2 high drain aspire 26650s I should get around 5.5A per emitter (6V ). I just tested a sliced XHP50.2 in a C8 at 5.5A and got 3100 lumens OTF and 69Kcd, so the full light should output around 22000 lumens and do 480Kcd. Will update when I get the mod done. :sunglasses:

Sounds absurd. I love it!

Very nice. I am always interested in anything hand crafted. I have made a few flashlights for myself and helmet lights for night riding. I am always ribbed for going overkill. To me there is no such thing…

I’ve repeatedly said this to peeps whenever they’ve asked why I did so much of this and that……ya know like buying a bunch of something if it’s a great deal…………

What’s not worth doing to excess is not worth doing.“

They usually just stand there speechless. :laughing:

Looks very impressive. Any chance for beamshots?

I’ll take some wall beam shots to compare beam size before and after, but probably won’t get around to outdoor shots like in post #35 for awhile.

Oh I actually didn’t see the pictures in post #35 because I was using my cell phone. Now I see it. The beam is marvelous! I wish the manufacturers would make something like that. Maybe even use XHP35 HI.

Easy B,

Exceptional minds think alike, and history repeats itself...

When I first started this hobby 15 years ago there was a one man army named Wayne and his company Elektrolumens that pioneered the formula behind your outstanding design. CNC machined head and body lights that utilized clusters of LEDs and reflectors to achieve a massive flood wall of light with extraordinary throw character as well, the holy Grail of flashlights to have them BOTH.

He made his own designs and I was awestruck with the incredible performance of geometric array lights. He started off with 5,6,7 and up to 12 in one gargantuan head. Back then using NiMH batteries because LiIon had not yet evolved fully enough to supply the insane parallel current demands.

Wonderfully you have included active cooling, a necessity for the insane waste heat your array will make for continuous duty. I suggest going a step further and going to a liquid cooling or reverse Peltier design for even greater effeciency.

Standing ovation BRAVOS for your ingenuity and skills. I can't wait to see how it evolves and WOWs even the most crusty die hard of us.....

Best of LUX :-)

“EasyB” Now that’s thinking outside the box :beer: You are gem here and I love to see people like you making their visions into reality. That is quite an accomplishment, I am very impressed.

Since you mentioned modding this Monster, you may be interested in these reflectors for maybe closer to 2 mile range. They are 2X deeper than the C8. :beer:

Mmmkay, are you going to dare with 19x or 43x versions? LoL!

Cheers :-)
