my 800 lumens for $55 project

[netprince]

I'll start by saying, I love seeing picture build logs fellow CPF members produce, this is my first attempt to produce a build log... 🙂







This is the build of my 800+ lumen mag for $55 project... for background on the project, please see the design page:

How do I get that price?

• 3D MAG led host, black friday special: $15
• Shinningbeam 2.8amp driver : $7.50
• Custom heatsink (thanks Tekno_Cowboy): $15
• XML LED: ~ $10
• That leaves a little $$ for consumables... wire, epoxy, etc

Cut down the reflector

Cam removed from the reflector, leftover plastic filed down

Comparing the stock heatsink to the new heatsink

Test fit the stock heatsink (I buggered it a little with the drimmel, whoops)

New LED. XML T6 bin 2B color

LED star filed down to fit (designed the heatsink hole a touch too small)

stock switch assembly

switch parts before modification

after switch mods

wire left over from previous build... mil spec, 22 guage silver coated stranded copper, teflon insulation

used deoxit gold to reduce contact resistance

Contact parts treated with deoxit gold

Switch re-assembled

shiningbeam 2.8 amp driver, accupower 10Ah LSD D cells (not included in price)

Test fitting driver heatsink

Driver attached to heatsink, attached to LED heatsink

LED wired up

test fire the LED, the lights are still on, but the camera adjusted for the bright LED

entire heatsink assembly sunk into mag tube

final product

No beamshots yet, but it is bright!

Great build thread! But, its missing something. I'm interested in seeing beamshots 😀, particularly to see the color of this 2B bin.

This thread was cut short by the CPF big downtime. I'll see if I can still find the beamshots...
