Hi Ernie,

There are a number of different kinds of drivers in that selection.

There are various output voltage ratings, including ones suitable for 12V LEDs.

There are various output current ratings.

There are various ways they can be "dimmed".

Some are designed to be powered via/controlled by a "standard" AC dimmer.

Others are designed to be powered via a fixed AC source and to be controlled by a variable DC voltage, by a PWM modulated signal, by a variable resistance (built-in or external), etc.


Of the ones listed I've only used these BUT they used in an application where the dimming range was 25% to 100%.
