Ultra powerful flashlight - up to 17,000 lm

Ultra powerful flashlight - up to 17,000 lm

I used an LED with a luminosity of 1,750 lm, but it is also possible to use a 17,000 lm LED.

BOM:

• LED chip 1 750 lm 
• 5010 Fan - For cooling the LED
• 3010 Fan - For cooling step-up/down 
• Step-up convertor - Voltage boost for LED
• Step-down convertor - Voltage reduction for fans
• 40x40mm heat-sink - I used one I found at home.
• Toggle switch
• DC socket
• Some cables
• 4x li-ion batteries 18650 - connected in series (4S)  
• Li-ion battery protection
• M3 heat inserts and long M3 screw (I used spare parts screws from the MK3S kit)
• Optionally some lens

You can use a more powerful LED if you want, you'll probably need to use a different step-up converter.

The photo shows an LED with a luminosity of 1,750 lm. One photo is with optics attached and the other without optics.

I plan to make another flashlight with this LED. Stay tuned 😀
