Just before ordering parts your opinion about those for the builders have already done :
Photocell Silonex NSL-7530 Yes
Lamp, Screw Base, 1.5 Volt, 25 ma This is too tall to fit in a 1790NS enclosure, so I used the tiny 1.5v 25ma one with wires already attached (SmallBear)
Trimpot 500 Yes
Lamp driver 2n3904 Yes
R48 68,100,150 or ?  whatever the schem says
2n5089 Yes

Quoting the Geofex parts list:

lamp bulb- Radio Shack 12V/25ma

The 1V5 lamp worked/lasted?

The 1V5 lamp worked/lasted?

Worked great until I killed it by turning the trimpot too far. Small Bear lists a couple of 1.5v bulbs specifically for the univibe

So what about the small bear 12v 40mA ?
