And yes.. A 100W LED is alot... It is approximately 9000 Lumen. A car on high beam produces about 4000.
And that sums up why I made this. It's awesome!
Let's get to it.
Step 1: The Idea
I have worked with some 10W LEDs in the past and they produced a lot of heat. Therefor I wanted to have a great cooling system that could cool down the LED.
The picture is more or less what I came up with.
This should somehow continuously cool down the led.
Step 2: The Electronics
Now that we have an idea of how we want it to look like it's time to go shopping!

Step 3: 3D Printing
Because why not!?
While I was making the 3D model i saw online some other projects similar to this where they used PVC tubing, and was about to do that instead... But hey when I got an excuse to 3D print.. I 3D print!
Step 4: Assembly
Now that the 3D printed model is printed to fit all the components it was very easy to screw everything to place.
I gradually soldered the electronics while I worked my way back to the end compartment with the batteries.
The battery was made by 4 old laptop batteri cells (18650). If you know how this process works you can see I have tested these and marked the capacity on the cells. this helped me to find 4 more or less similar cells.
I can definitely recommend to scavenge these batteries whenever possible. You never know when to use them!
Step 5: Test!
I made mine without a BMS system. this means i need to charge the battery on a battery charger as you can se here. If you just want a power input to charge the cell a 4s BMS is recommended.

I will try to get some better pictures for you so you can se really how much it lights up. It's a lot....
I hope you enjoyed my instructable and i hope you want to make one of your own!
If you liked this projects dont forget to throw a little vote in my direction. It definitely helps me out and it helps me to know what you want to see more of nex time!
See you next time!
