--- Quote from: RandyT on November 06, 2009, 01:05:34 pm --- One thing to remember is that there are no "magic" LED's that can put out more light than others at the same current and voltage levels. The light can be concentrated, and therefore be brighter in a smaller spot, but the volume of light (energy) will remain constant. So always consider the voltage and current when looking at the overall light output of an LED.

My apologies. That was just a random image I pulled from google. [These] are the ones I got the stats from. They are Chinese I know and the stats may not be correct but thats why I was asking about Superflux LEDs in general. |

You need superflux LED's to build a Flux Capacitor, duh! :afro: |

Do you see a significant contradiction? |

You might get 8000mcd out of them with a 100ma 0.1msec width pulse, but not at 20ma constant. My guess is that the LED wouldn't last 10 seconds after attempting to get that kind of output from it. In the absence of a real spec sheet showing response curves, you can pretty much take the ebay ad with little more than a grain of salt. RandyT |
