Driver List Database code 16 December 2019
Footnotes 10 August 2016
Not included in the Driver List 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.
BTW, that retailer, Ledstok, gets the Class Idiot award for reusing
all their driver URLs for LED and LED optics; in the case of the example
above, a triple LED board. They still have at least some of their drivers
A New Zealand maker has some LED drivers detailed
online (also scattered around other part of the site), but apparently
not purchaseable online. (The horizontal scrolling of that site is a
bit sad too.)
Australian seller LEDsales has a range of LED drivers and resistors, but sadly their international shipping is more expensive than most of the drivers. However, they do list better than average information about the drivers.
Manafont lists some drivers like this (5 LEDs) and this (3 LEDs) but doesn't include really important details and the drivers can only be found by luck. Important details not included are input voltage or if a voltage is mentioned, whether it's a maximum or minimum input voltage.
LED Overview - a simple explanation of how LEDs work, the different tints available, and a brief list comparing various types of (mostly Cree) power LEDs with links to inexpensive representative examples.
LED resistor 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. None of these calculators is perfect so if you have a regular use for a resistor calculator you might like to try them all and see which you prefer.
LEDcalc.com - graphical
representation of circuit and results (including actual calculated resistance) are clearly presented. Cannot cope with currents more than 2 amps or resistors less than
1 ohm. Note that it uses the actual resistance to calculate power dissipation, not the recommended value (which is a minimum of 1Ω).
LEDCalculator.net - wiring and circuit diagrams, and a direct URL for the values you have just entered. Does not cope with recommending resistor values less than 1 ohm; if it states 1Ω do not believe it.
- not the prettiest results but as well as wiring and circuit diagrams gives ASCII versions as well, and where appropriate provides several wiring arrangements. Does not cope with recommending resistor values less than 1 ohm; if it states 1Ω do not believe it. Does not give resistor colour code diagrams but does state the stripe colours.
Hobby Hour LED Series Resistor Calculator - gives a circuit diagram and the nearest two resistor values (higher and lower than the calculated value). Cannot cope with series/parallel arrays, and half the resistors it recommends are not commonly available values.
myresistor.com - helps determine the value of the resistor based on its color code.
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.)
Driver Wiki. A brief explanation of drivers. Some other useful info
on that site too.
LED Supply's driver selector to help sort out the varieties of BuckPuck, PowerPuck, BuckToot, MicroPuck, BoostPuck, and so on.
PR Flange Drop-in List on CPF. LED replacements for a PR flange
incandescent bulb. Unfortunately the list is old and has broken links.
