800 Lumen Rifle Spotlight

[creetech]

Hi everyone,

I have finished building an 850 lumen rifle spotlight this week and thought I would share. I have been working on this project for a little while. The light uses 4 Cree Q5 leds with 4 aspheric lenses. It has amazing throw, like nothing I've seen before. The only brighter led light i have seen is the lenser X21. I was able to compare my light to the X21 on its brightest most focused setting and it only just beat it. The X21 is a 950 lumen light.

Anyway, some specs:

4X Q5's running on 1000mA or 330mA
Toggle switch with High, Off, Low modes
Reliable Buckpuck regulator
Cut down maglite body with heatsink disc inside
Water resistant (Probably water proof, haven't tested it yet.)
Has a 1 inch mount which can fit most scopes or a heavy barrel.
External battery pack. (Requires 14.8V minimum, on 1.2 Amp hour battery, I get about 1 hour on high beam, three on low) Any batteries can be used, lead acid, lithium poly, rechargeable etc.
Should only be used on high beam for about 20mins at a time. Low beam is very bright anyway.

If anyone is interested, I might be persuaded to build some more..

That is a very slick innovation...

is that a .223? Sick mod by the way...:wave:

wow. very cool.

 

[bigchelis]

Now that is a freaking cool light, Usefull too.

Oh, and you do loose around 50% of the lumens by going the aspheric route so its 400 lumens:nana:

Can you show more detailed pics on how you did the mounting & modding of the body? I'm going to be getting a chunk of a body soon, and that idea is perfect!

Hey,
Which heat sink did you use for this mod? and is it a D size Mag? its a very smart looking and clean cut down, looking at doing something the same for my bike.

Cheers, acezone

Not sure about that one bigchelis, all aspherics are different. This one is definitely up there as I have compared it to a 950 lumen light and its nearly as bright. Its definitely not 400 lumens

Thank you, no its my 10/22 :laughing:

Hi, I use a d mag, cut down of course. I made the heatsink myself from an aluminum disc which I machined to fit inside the mag head.

nice light :twothumbs

The battery pack I am currently using is 2 Lead acids. It's actually pretty small as I don't need a very high Amp Hour rating to run for a few hours. I use a 6V and 12V in series to give 18V, 1.2 Ah. Sorry I don't have any pics at the moment but I can try and get one later.

Cheers

How do you carry a lead acid battery pack on a hunting trip?

If the budget allows, I think you'd increase the enjoyability and usefulness of your rig much more with a 4-5 cell li-po. It will be a fraction of the weight and will provide a more consistent power supply.

Good li-po prices can be had at hobbyking.com

 

[creetech]

Yes, The Li-po's are pretty cheap, it's just a charger that takes the price up a bit. The Lead Acids aren't too bad, I get them very cheap.

Are you serious? They really aren't that big or heavy, only need 1.2 Ah remember.
