Im looking, just as a fun project to try, to replace the filament in an incandescent bulb with some white LEDs, to cut power useage and to get white light, rather than warm light.
First of all, Im looking at using **broken link removed** LEDs. How many should I use, per bulb, to get around a 60-80w incandescent equivalent?
For driving the LEDs, Ive found a few circuits:
**broken link removed**
**broken link removed**
**broken link removed**

(images taken from respective pages - see url).
Which would be the best (and most cost-effective) to use?
