Introduction: DIY Mega Head Flashlight With 6x10W LEDs
This is my new head flashlight. I know it looks a bit strange, but it shines as much as the lights in the car. I installed 6 leds each with 10W. All powered from a 14.4v battery from a cordless drill. This is the most powerful flashlight I have had in my entire life. To build this flashlight I used the previous project ( Diy LED lights panel for 5$ - Cheap and Easy 6 x 10W ) where I step by step described how to do it.

Step 2: Measuring and Cutting
Below is an example of plexiglass cutting.
Step 3: Grinding the Edges
After cutting the plexiglass the edges are not smooth, that is why I am sanding them.
Step 4: Drilling Holes
Now I can fit plexiglass into a plastic box and drill the mounting holes.
Step 5: Mounting LM2596
Time to mount the LM2596. LM2596 is step down converter and I use this as leds driver.In addition, I added a rectifier diode, this protects against reverse polarity.
Step 6: Adjust the Current on LM2596
Adjust current on LM29. Just now I set the current at 0.5A, it is only for testing.I use a screwdriver to set the correct current.
Step 7: Putting Everything Together
Now I can put everything together and test how it works.
