Homemade LED flashlight for spearfishing How to make Monster w LED flashlight that can light the clouds with mah li-ion battery pack and huge double lenses. For night work, we need a flashlight that is very bright and can be used for a long time. There are 2 reasons behind this project. LED Torch Free energy. Idea of energy source is taken here 3. Parts: dc-dc step up boost converter Ebay: ebay. Over a Ever wondered how LEDs actually emit light?

This video is for you! Also, regarding Blinkist, visit www. The LM regulator gives constant 1. Connect the two outputs with a resistor. The closest resistor value I have found is 1,5 Ohm, the output will be mA. Build a frame, you can use for example wood Connect the lipo Turn on the switch Great project, but you should pay attention to a few stuff. If the battery you're using is dropping by 1 volt for example, then you're getting 11 volts on the LED, what is not cool, cause you're not going to use the Led's full bright I noticed in the video that the power of the led is like 9v only, it should be way brighter.

If you're not using 12 volts on the LED, then your heatsink could be a little smaller. For a way smaller heatsink, you can try using a heatsink with a 12v fan, it has like 60 millimeters of diameter only. That driver can easily be found on ebay, it has an output of 12 volts and provides the exact amount of current that the 10w LED should receive, which is ma.

Reply 7 years ago on Introduction. Hi, a 3s lipo has a However, fully charged it s well above 12volt. A 4s lipo would be a better fit because the lm has a voltage drop and you get pretty close to the 12v the high power led needs. You get lipos and charger in rc shops like hobbyking.
