If you are looking for the absolute most bang for the LED buck, check out the Japanese Nichia 5mm LEDs. They are incredibly bright and there are Chinese knock-offs that are very close but much more cost effective. Our factory uses about 80 million Led's a year and have found the 11 Candella high bright Chinese knock-offs to be pretty good. You can power them to about 60ma without frying them. The Nichia's are about 80 Cents and the Knock-off's are anout 20 cents in white. Daniel Deutsch (Orlando) 15779 & 3356
