Retrofitting LEDs in a Dynamo Bulb

Step 12 Final thoughts , A note about Resistors And things that just didn't fit into another step

As you can see this array is reliable , shockproof and it will not burn in a loooooong time ,

I just have a single test Picture since where i live is raining , but believe is as bright (or more!)
than the Original bulb .

Yes , i know that there are several more powerful LEDs in the market , but I was too lazy
to wait 2 weeks of shipping, so i went to my local surplus store and bought them , you may also
salvage the LEDs from a toy or a Chinese flashlight , or better , order them online .

About Resistors :

As most of you know LEDs must have a Current limiting resistor to prevent burning

MATH time , yay!:

5.9 volts of the dynamo minus 3.3 of the LEDs is 2.6
2.6V divided by 0.075A = about 35 ohms (thanks PKM!),the neares safe value is 33

So I just soldered a 1/2 watt 33 ohm resistor in series to the array , I haven't suffered any
disgrace so i think is pretty much OK ,

Resistor color code is orange orange black gold
