Does anybody know how the Greenforce dimmers are working in combination with a boost driver? They work with power off and on quickly but what kind of a board and how to connect it??

I'm not sure exactly what you want to know, but I'll take a stab at it.
There are two ways to dim an LED: put less current through it, or turn it on and off so fast that the eye can't see it (about 100 times per second), and the ratio of on time to off time determines the brightness. The former is called analog dimming, the latter is PWM.
There are advantages and disadvantages to each method, and some systems use one, some use the other. Some even use both.
If you want to wire a dimmer into an existing driver, you have to know about both the dimmer and the driver, as methods vary. Some drivers are not suitable for use with dimmers, and some have dimming capability built-in.
I don't know the Greenforce lights in particular, but I would guess that they use PWM dimming that's built into the driver. It might be analog dimming built into the driver, but not likely it's actually a separate dimmer.
Hope this helps. If not, keep asking.
