Turn an ordinary house bulb into a bright HID lamp! only 35Watts. HID or XENON lights are the really bright headlights you get on some cars like the new audis, Go retro and chuck it in a light bulb! i mounted it in an old lamp.
This is my first instructable; so just comment if i need 2 improve on anything...
i could have made loads of different instructables but just couldn't be bothered here we go......
Step 1Take out the bulb and fitting

The fitting is held on by a little 10mm nut and bolt, unscrew it and the fitting comes loose. your going to have to cut the plug with a pair of sidecutters to feed the wire through to take out the fitting
The ballast has a 12V supply to the battery.
The bulb is connected to the ballast.
I bought at a price of $ 30 ballast & bulb
its a 35Watt bulb. 12Volts 7Ah
35/12=3A (2.9A)
7/3=2.5h (2.4h)
so i would say 2 and a half hours
Thats on average, constant use.
the bulb draws in a lot of current when switched on but as time goes on it goes lower; so its not a precise measurement of time, just a rough idea
I think thats how u work it out anyways
