Has anyone used these dimmers? http://www.periheliondesign.com/egpavr.htm

* Any quirks?
* It doesn't appear to be Pulse Width Modulated (a bonus)
(data Sheet here: http://www.national.com/mpf/LM/LM317.html)
* ON/OFF switch is nice
* How do they fit in the very limited space provided for by the RV10 switch rail?

Thanks,
Jay

Jay -

I have two.
One driving an LED strip from Stein.
The other driving the LED map light, also from Stein.
They're slightly bigger than the typical DPDT switch - not wider, but taller
on one end.
They seem to work well.
Note that you only need a 1/4" hole.

I've been VERY happy with Eric's service.

I have not used the Perihelion dimmers but I have made a few voltage regulators using the circuit in the data sheet. I use the LM 338 regulator which gives me 7 amps max output and 5 amps. constant current. For me, it is a pretty good regulator and reliable circuit. You should be pleased with the dimmer.
