A wide variety of 0 5 volt led light bulbs options are available to you such as e27 e17. Get it as soon as sat sep 19. 12 99 12. If you make 20 ma flow at 13 v then at 5 v the led will still work but at a lower brightness.

Normally if you want to light up a blue or white led you need to provide it with 3 3 5 v like from a 3 v lithium coin cell. For that 20 ma you need a 500 ohm resistor.

But a 1 5 v battery like a aa cell simply will not work.

As you can see the resistor value increases as the supply voltage increases. 500 ohm resistors are hard to find so get some 560 ohm resistors that s close enough and use one. Always use a series resistor. The blue led has a typical forward voltage drop of 3 2 v therefore a 5 ω resistor is required when using a 3 3 v supply voltage.

But using the joule thief it works like a charm. Not only does it work with a brand new battery but it works until the battery is nearly dead down to 0 3 v.
