Another SAfrican ;) I have seen led lights - but they all are extremely expensive. If you want to use to replace incandecent bulbs, CFLs would be a lot cheaper (IMHO). Some of my friends built their own lighting system and they ordered the LEDS directly from a mail order electronics store. This would probably be the cheapest.
