Changing an Halogen Spotlight Into an LED Spotlight

This is an very easy instructable.
At first i took an normal 100W/75mm halogen spotlight and remove the reflector and the socket.
Then i took an 8W LED modul from Seoul Semiconductor, which could be connected directly to 230V. I fixed it to an heatsink, using thermal compound. The wire has to be solderd on the module.
At least, i screw the heatsink into the housing, using the thread which was used for the original socket.

So the lamp has now only 8W instead of 100W, it don't get so hot anymore and the brightness is less then before but enough.

For more light, i think it is possible to assemble two modules.

You need:
a screwdriver
a soldering iron
a little bit of wire
1 halogenspotlight 100W ( about 10€)
1 8W LED Module 230V ( about 10€)
8cm heatsink
a little bit thermal compound
2 screw long enough to fix the heatsink

Important: because this is a lamp with 230V you should be very careful. And don't forget to connect the earth

    Nice project!

    Is 8 watts led lamp enough? I think it should have much higher wattage to match that halogen lamp.

    This should be no ploblem, because the LED-Module is availablefor 110V too.

    I don't know if it is allowed to post a link, but you can buy the modules at mouser dot com
