Telephone Line Powered Ultrabright LED's

In this video I will show you how to make a very simple Ultrabright 10 LED light that is powered by your 50VDC phone line. In the event of a power failure, you will have no reason to be left in the dark! Simply plug this circuit into your phone jack to have a nice LED light. The power consumed is low and FREE. Make sure the power consumed is kept low to avoid problems. If your circuit does not work after assembly, try reversing the telephone wires on the PCB. Using Ultrabright Pihrana LED’s is best, and will give you a nice color light, as well as a nice wide beam. If you add a switch to the circuit, you can place the light in a holder to make a nice light for your bedroom(reading light…etc). If you have any questions, please post them in the comments section!

The schematic does not get any easier!
