Step 10
Now cut the legs so that it matches the original bulb legs, equal in lenght.
Job done! It's time for a test. Connect the bulb to a 12V battery (car or anything else providing that voltage). Hold your breath and...
It's working! The photo actually does not display the amount of light generated as it's blinding if you stare into it directly.
I had to seriously under-expose to make this visible. You can use any type of 5mm LED to make ledbulbs just make sure you know the forward voltage and current since it will be necessary when calculating resistors. I made blue, red, yellow and white ones, with successful results. I also made 6V LED bulbs I use in flashlights, replacing the entire flashlight mirror with one of this bulbs. In this case, the current consumption should be ( according to the scheme ) 220mA. It actually uses only 200 mA, or at least that's what my multimeter says.
Here are some LED bulbs I made, 12V and 6V ones. They generate virtually no heat and the most powerful one I made takes 12V@200mA and has 6 pcs. of 0,5W LED's. These LEDs were pretty expensive but the light output is great.
The type of LED's you use is important since a more dispersed light will be better than a concentrated one. You could also file the LEDs prior to making the bulb so as to have a more uniform light. These LED bulbs can also be used in 12V AC spot lamps if you don't mind the 50Hz flicker. But the best results will come out from 12V DC.

We've been planning a new "hang out" cabin down by a pond and these may work out just perfectly for it.
Thanks for sharing and great job with this instructable!

I'm quite sure this would be very nearly 100% power going through, not 50%.

Very cheap White LEDs. If you buy in packs of 25+, bulk, they only cost .68 Cents. Very good. plus you will have 3. Pack of 25 runs for $17. This is a great site for tons of cheap components.
