/ hpcvca:sci.electronics / scott@hpcvca.CV.HP.COM (Scott Linn) / 3:22 pm Dec 3, 1990 / >HP makes ones up to 5 times brighter (25 Candela). They are around $12. I made a mistake. The HP leds are min. 8 candela, typically 15 candela, and maximum 36 candela (all at 20mA). By the way, if you are going to use an led in something like a flashlight, you would be better off not looking at the strict candela number, because most of the high-brightness leds have an extremely small angle of light output (typically <= 4.5 degrees). A high-brightness, wide-angle led would be better for this application. Scott Linn
