BUILD PROCESS - liquid cooling and first test
So I finally got around to installing the liquid cooling and LED to do the first test.
Filling the cooling loop is not very difficult, the self-priming pump makes it really easy to get water flowing, then all that’s required is to put both tubing ends under water and join them, that way no air bubbles get inside.
One problem I have at the moment is that the water pump is getting extremely hot, so I need to find a way to heatsink it to the body, I guess 30ft of tubing adds a lot of restriction!
The flow rate is still very good though, the tiny pump has no problem moving the water since it is not an impeller pump, it uses a diaphragm.
Here you can see the coil in place. It is not attached to the body with thermal compound, but I plan to do that only once the body is finished and anodized.
These are the screws+springs that are used for mounting and focusing the reflector. They actually worked very well in my testing at the end of this post, however the screws are a bit too short so I will have to increase the depth of the countersinks and add some washers to the springs.
Test fitting the reflector.
I only have 3/6 of the batteries in, but the black shockli cells look awesome 
Here is the small pump used for cooling. This is what is currently getting very hot after a few minutes and needs better cooling. How ironic, the pump used for cooling is what needs the most cooling.
The light is jam packed with wires, tubing, and batteries. In the future I need to allow for a bit more extra room in my designs for ease of assembly!
The LED mounted on the cooling block, mounted on the spider. So far 0 leaks
Screws holding the MCPCB are too thick, and block some of the light, so they will be replaced with some lower profile ones.
I used the 1 amp DMLN Synios LED for this testing.
Test before putting the reflector in.
Mounting the reflector is probably the most difficult part. The copper tubing unfortunately only lets it fit through the front of the light, which means it is not possible to see where the screws and screw holes are to line it up. If there was no liquid cooling it would have been a breeze. Design flaw 
Despite all these small problems, the light works!
First beamshot! (not focused perfectly because of the screw length I mentioned before)
