Powerfull led torch (770 - 1300 lumen) with 18650 battery

thingiverse

I use an x7 smd led available on Amazon at https://www.amazon.it/gp/product/B07BVTNS6Y/ref=ppx_yo_dt_b_asin_title_o06__o00_s00?ie=UTF8&psc=1. An x1 button and an x1 18650 battery are also required. Additionally, a cable for 220v is needed. The led can handle all the power of the battery because it supports 3.6 volts. However, using this much power can be hazardous because the current consumption requires a high current flow. Therefore, it's essential to use a copper cable rated for 220v to prevent fires. To preserve the leds and extend the life of your battery, you can add a resistance before each led to reduce the lumen output. I'm using an old 18650 battery from my very old laptop with a capacity of 3.7 ~ 4v and 2600mah. The torch is expected to produce around 770 lumens, but I've overloaded the power supply of the incoming LED to 1300 lumens. I've tested this with my DIY lumen tool, which isn't very precise, so please forgive any inaccuracies. The battery life is approximately 45 minutes, but the battery is easy to replace when it runs out. Here are the calculations: 2600mah battery 2450ma leds consumption = 0.7428571429 If these calculations seem incorrect, please let me know. After printing the torch, you need to screw and unscrew it a few times to allow any excess plastic to be consumed in the screw thread.
