After answering yet another question on LEDs, (This one), I had a look at what is online.
The totally rubbish calculator that came up in all the online searches a few years ago, **broken link removed** has now vanished, but the algorithm behind it is back, with it's own domain, cookies, advertisements, a really long disclaimer and pretty pictures that are of little use.
Having seen that, I've updated mine to be a bit nicer to look at, and it's here. The one on this site is technically very good but it doesn't seem to me to be easy to use.
I suppose this is just a rant about how pretty pictures draw more clicks than stuff that works.
