Quark Bikelight

[rayman]

A friend asked me to build a bikelight for him. At first I thought I take the head of a MiniMag and put optics, led and driver board in it. But the heatsinking will be very bad. So looking for another possibility I got another idea.

My idea was to buy a 4Sevens Quark head (regular or turbo) and the fitting tailcape. Then just wire it to an external battery and glue the head and the tailcape together. Then just use a Twofish Lockblock to mount the light to the bike. Maybe I buy the 123^2 Turbo head and use an external 2x18650 battery pack. Wouldn't that be a nice bikelight?

It might be worthwhile to get the light body, too. It ties the head and tailcap together, helps a little with heatsinking, and gives the twofish block a place to hold onto. You will have to drill a hole in the body to get the wires in. You could solder the wires directly to the head and tailcap, but I would suggest instead to build a dummy battery from pvc tube, with a washer on each end to attach the wires. Add a bolt to the positive end to create an appropriate nipple.

I think it would make a great bike light.

I made a simple one with just a P60 module. All you need to do is glue a glass or plastic circle in front of the reflector and solder wires to the center spring and base and you're all set. Also this is a very inexpensive setup instead of buying a whole flashlight and disassembling it just for its head.

I made a simple one with just a P60 module.

Does it not overheat? I Also made one (out of two CREE R2 modules) and needed to add some copper pipe to aid in cooling.

Here is how I made it: Double barrel CREE R2 bike light. – almost finished.



It seems to remain "almost finished" as Dx has delayed delivery of my new lenses somewhat Meanwhile I just use it as it is.

Yes you could just get quark parts but it's expensive.
A budget DIY could do $20
empty P60 modules save time and add build quaility

I asked my friend and he said that he wants a MiniMag-bikelight.

Too bad, they are ugly ;-)

Can not imagine you can get a lot of light out of it. It's even smaller than my own 'smallest' light which has an SSC P4 and an 800mA driver:
