Drivers not yet added

Not included in the table are other boards including (but not limited to) the following. That they're not included is no reflection on their price, quality or suitability - I simply haven't got around to including them yet.

• Meanwell LED drivers including IP67 models. Retail example.
• Various FLu-PIC models.
• SatisTronics have LED drivers which appear to be more expensive versions of some of the DX drivers, and shipping is extra.
• An RGB controller is listed on this page, while a PWM-only RGB controller kit can be found here.
• Oddball drivers like this one which don't have full specs, on a site which is horrible to navigate.
• Another driver without full specs.
• Drivers with the LEDs built in.

LED calculators

Enter starting values and it tells you what resistor value and power rating you need, with a picture of how to connect the circuit.

• LEDcalc.com - graphical representation of circuit.
  Cannot cope with currents more than 2 amps or resistors less than 1 ohm.
   
• LEDCalculator.net - provides wiring and circuit diagrams of circuit. Does not cope with recommending resistor values less than 1 ohm but does apparently use the correct resistance to calculate power dissipation.
   
• led.linear1.org/led.wiz - not quite so pretty but it provides several wiring options and ASCII diagrams as well.
  Does not cope with recommending resistor values less than 1 ohm but does apparently use the correct resistance to calculate power dissipation.
   
• led.linear1.org/lumen.wiz - tool for converting mcd (millicandela) and beam angle to lumens.
   

Reference

• MyResistor.com - Resistor Color (sic) Code Calculator.
   
• Velomania beamshot comparisons - find out just how bright an LED torch is compared to some other LED torch. An impressive range of beamshots, in an impressive range of locations. (Listed here because it's such an impressive amount of work, and it might help choose a driver.)
   
• CPF Driver Wiki. A brief explanation of drivers. Some other useful info on that site too.
   

Driver-related

• LED PR Flange Drop-in List on CPF. LED replacements for a PR flange incandescent bulb. Unfortunately the list is old and has broken links.
   
• Drop-in Module List on CPF. The complete kit, with a high-power LED, driver and reflector.
