Thanks “MRsDNF” , You guys are our inspiration to do those crazy things LOL
This is the spice that helps give BLF its flavor 
.
When corona is over there’ll be a get together at your house right….?? We can enjoy the beautiful view, feast and then shoot down aliens when it gets dark :laughing:
Great project CNCman :+1:
.
Thanks “pinkpanda3310” You guys are the best, we are just trying to keep up 
.
Rolling the .25 dia copper tubing into place.
Now some copper head parts for water cooling the led.
Center tube and water inlet for direct flooding contact behind the led.
These are ears for maintaining center position.
Added a small reflector to try to keep the light in the mirror and not in me eyes.
.
Here we will finish the first build with 1 x XHP70.2 @ 10A 6V.
Battery box from .125 plexyglass.
Bending the plastic was tricky, many mistakes were made and the lessons learned were helpful on the second box.
Mounting bracket.
Forming the driver cooling tube with a heat gun.
The driver is mounted in the handle.
Here is the test at full power at 10 amps 6v. Unfortunately I thought I took some beam pics but not. 
This is the end of the first build. After this test it was clear more light was needed.
That was some clever coppersmithing to make that heat exchanger tube—got some moonshiner in ya?
Could you adjust the tube position to make a difference in the light coming out?
Very impressive watercooling setup.
Am I missing something, or are you somehow getting 6V out of 5 18650s?
Cool. It’s fun to bring oddball ideas to fruition.
Sweet. Now where’s the night pictures? 
Beamshots?
Nice job on the water block and spider. Now I have some ideas on how to do mine
Sorry guys, grin, MRsDNF , I thought I took some before I tore it down to mod it. But the beam was not very good. However after modding it improved significantly. I will get some beam shots tonight and post them.
.
Yes, that is where its at now “tuning”. I have another reflector on order to try improving the beam. The one in it now has been chopped up and a polished Stainless Steel straight .750 long extension added to the end, it gets very hot very quickly. The reflector part stays cool because it reflects the light but the ss extension absorbs some light and gets hot.
.
LOL, Yes, sorry for not clarifying that. The 2 x 30Q’s are wired to only power the led. The 2 x 18650 EBL’s power only the water pump. And the small single 18500 EBL powers the fan for the driver. I fixed this on the mod, wait till you see it !!
Ok here is the final control box mod for this light. I will finish up tomorrow with beam shots and led mounting.
NOTE: more specs were edited into the 1st post.
After finishing it originally, there were significant improvements that I could not resist doing 
, so we ordered parts and ripped it up. Sorry about some of the picture quality, we just purchased a new camera and still learning how to use it.
.
Here are 2 power supplies, power moniter, shunt, driver, mcpcb and batteries. Working on positioning everything.
.
After struggling with bending the plastic on the first battery box, it was time to get control of it, LOL.
It came with a protective paper covering that was peeled off later.
A little JBweld in the corners.
Mounting the fans and switches.
Mounting and testing the 2 power supplies. Left one is for the water pump 8v, right is for the 2 fans 5v ea.
The left one is set to monitor input voltage for the 4 x 18650 red EBL batteries.
MT09R driver from Lexel in a copper mount.
Wiring it up.
Glueing the hinge in place, painters tape is your friend !
Finished with the control box. The 4 x 30Q’s will power the 4 x XHP70.2 leds
Powered up.
.
Tomorrow I will finish it up with beam shots and the led copper head.
.
That is so neat.
that’s some great “sheetmetal” work with the plastic for the control box, very professional looking like it was store-bought. Can’t wait to see the final assembly and beamers.
Thanks guys
hey CNCman, hope yall survived the hurricane without any flood damage.
Did you happen to measure the dome height of the lid—or maybe the “sag” depth of the center with respect to the edge? From that we could calculate the approximate focal length of the “mirror” and where to put the light source to make a big flood light.

No problem with Laura here, we are near Bay St Louis MS.
.
Here are the dimensions for the 12” Pot Lid. I have been adjusting the head position between 7.5 to 8.5 inches ( focal length ). Ordered a medium size reflector to chop up for keeping the light inside the mirror. Right now the weather has been raining , so I hope to get some pics tonight.
.
This was an attempt to make a throwing light that failed. If it had a true spotlight mirror it would have a chance of success. I will get that mirror when it is in the flashlight budget.
