newbie here.
I bought some new outside LED lighting fixtures for the garage and front door. they are too bright and annoy the neighbors. they consist of 3 LEDs in series running off a 10V 700ma supply.
to dim them I put a 2.2k resistor in series. now they flicker.
I then put a 33uF cap in parallel. flicker is reduced, but still flickers.
I also tried to disconnect 1 or 2 of them. the remaining ones flickered.
is there a quick way to dim these without having to build a fancy PWM controller??
and, could someone explain to me why they flicker? I'm an EE but have long forgotten the basics of LED circuit design.
