Nettet9. apr. 2024 · Typical LED current consumption 0.02Amp, 9V/0.02A = 450 ohms. Then you would need to construct a series circuit with one LED and one 450 ohms resistor. This would consume a total of 0.02A into a sum resistance of 600 ohms. The LED would light up and will likely last for some 100000 hours if treated properly. Cheers:) NettetA low efficiency LED can mean that even a high power UV flashlight is not actually producing much useful UV light output. It isn't easy to determine UV LED efficiency, but generally, look out for lower-priced UV flashlights, as the LED chip is typically the most expensive component in a flashlight, and low efficiency values are typically the result of …

NettetStep 2: #2 Nothing Is Exactly the Same on Both Sides. And so the sides of LEDs aren't. If you will take a closer look at the LED you will notice that one side of it is flat and again that's not a manufacturing error, that's a mark that lets you easily determine LED's polarity. Lead next to this mark is negative another one is positive. graphite glass tile
