We've gone to using the new solar panel street light they're selling on the web . We get the one with 2 sets of 60 LEDS, though you can't get them any color but white. I went to Hobby Lobby and bought some colored clear plastic film. Each lens cover comes off with eight screws. I remove the foil reflector and put a green (though you could use red) piece of film over the LED's put the reflector back on and screw the lens cover on. Little tricky getting them mounted to a 3" pole but with the help of some big U bolts and a couple 5" pieces of 2X4 they tightened down nicely.
They work great for lighting up the area around and under the feeder. A couple of our feeders which are 150 yards or so from the stands so we use two of the lights to help light up the area. These lights stay on at 30 % power until they sense movement and go full bright for a min or as long as they sense movement. To be honest, we can't tell where the motion sensor is and they seem to have a mind of their own for going bright and dim when nothings under the feeder. All in all not bad. I paid $74 for each light and was simple to put the green film over the LED's.
