100W-LED-Flashlight

This project is an ultra bright LED-Flashlight. The Flashlight has a maximum Power output of 100W. A conventional Flashlight has about 0.5-5W. At night I can brighten my entire garden with it. In the future I will make another version with a microcontroller and a display where you can use the flashlight as a stroboscope and also dimm the light.

For this build I used following materials:

• 1x 100W LED
• 1x LED Lense
• 1x DC-DC Boost Converter
• 3x 18650 Batteries
• 1x BMS 3S
• 1x 5A Fuse
• 1x 40x40mm Heatsink
• 1x 12V 40x40mm Fan
• 1x ON/OFF Switch
• 1x JST-Connector (Charging)
• 6x M3 Threaded Inserts
• 6x M3x16 Screws

How to build:

1. Battery-Pack
   1. Connect 3x 18650 batteries in series
   2. Wire it up to the BMS
2. LED-Driver
   1. Connect the LED-Driver to the Battery-Pack
   2. Set the correct voltage (30-36V) (the more voltage you set the more power the LED draws)
3. LED
   1. Screw LED on heatsink
   2. Screw fan on heatsink
   3. Connect LED to LED-Driver
4. Assembly the rest
