Idea for a cheap regulated tricree magmod- tell me if its stupid

[copiertech]

hows about getting 3 of these http://www.dealextreme.com/details.dx/sku.1447 sticking them into a 3d mag with a bit of aluminium and wiring them in paralell? would it work? what are the flaws in my plan? anyone tried this?

 

[vinsanity286]

I am sorry to inform you that, yes, your idea is stupid.









:nana: Just kidding. Actually that sounds like a great idea. It would be quite a bit more money to get seperate reflectors, emitters and a driver. You will want to run the light with nimh d cells as alkalines would probably not hold up to the high current draw for long.

I retrofitted one of my small 2c vintage chrome lights with one of these powered by two 18500 lithium rechargeables. Bright with great run time... and cheaper than buying the component parts.

As long as they are properly heat sinked my amateur eyes can't see anything wrong with that plan.

 

[aml]

is there physically enough space in a mag head for 3 of those?

 

[Minjin]

I like the idea, but I am thinking even simpler. Mag 2C with 3x123A conversion. Buy one module, remove the reflector and the spring section, and adapt it to the pedestal. Use the stock Mag reflector. Keep it simple and it should be a very cheap, high performing mod...

 

[copiertech]

dunno if theres enough space, but i`ll find out in a few weeks when they arrive. i dont have a mag but ive got a 3d smith and wesson similar to a mag. ill add an extra switch to make it 2 or 3 level

Sorry for the information but 3 of them will not fit a Mag-head

Maximum are 4x20mm reflectors. I would go with a fat heatsink, specially made for those mods and the Led's, reflectors and driver you want.

Best regards

Here's mine, I had to shave the the reflectors on the LED lamp assembly's a little, I used the ones from dealextreme. It's not as bright as I was hoping for, does anyone know how to modify these LED lamp assemblies to be brighter? (note, I since changed to 9V, 3 CR123 cells, and it's now much brighter!)

Driving it with two Lithium Iron Phosphate 18650's good for about a 15 amp draw each! (though my wiring isn't good for that much current). 1300mAh per cell.

excellant work Tony, thats exactly what i was planning to do with the reflectors. did filing them increase the flood any? reading more about these drop ins i think i`ll probably be best running 4cs instead of 3ds. just need to wait on the postman now.

Running on 9V really makes them brighter it seems to me, as opposed to 6V, running on 4C's would probably not get their full brightness? Anyways as for flood, still a good spot, but the flood I think is slightly more, but not by much.

 

[copiertech]

Ow. I just scorched my eyeballs. 3d sized alkies drive my ones nicely.

 

[copiertech]

made it with a 2 stage reverse clicky, off-on(1led)-off-on(3led)

 

[Pumaman]

great idea guys

 

[Long John]

But why do you not swap these ugly reflectors against cheap IMS-ones?

The beam would be much improved and the optic too.

the beam is perfect for what i want, nice and smooth, no rings, wide bright spill and a large spot. no point in spending any more money when i`m happy with the result for $37.50

Howdy copiertech,

Could you give me a little more idea of what you did with the 3 individual modules as far as wiring them into the light? Also, any idea of your runtimes with 3D alkalines? Thanks.

Derek

i havent done a runtime test but when i get a chance i`ll measure current draw. i taken a 2 stage switch from a 10w k2 golston copy, wirer the batt+ to the middle pin, wired one side to 1 lamp assy and the other side to the other 2 then put a low vf rectifier diode from a switching psu between them to give 2 levels, 1 on or all 3 on. the next mod will be to remove the battery tube off an old 9.6v makita drill i have, put a belt clip on it and a bike frame mount and run wire to a spare tailcap as the battery tube screws off the switch section of this light to give a sightly smaller than 1d length and its the same thread as the tailcap and its very bright on 9.6v and i have 3 2.0a battery packs and a 45 min charger. itll be an interchangeable light engine with 2 battery configurations.

Hey, nice find !!

 

[Derek Dean]

Hey, thanks for detailed description copiertech. Very cool. I may give this a shot.
