100W LED - Flashlight

Welcome back!

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.

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.

Now that we have an idea of how we want it to look like it's time to go shopping!

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!

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!

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!
