I need help with a problem I cant seem to solve.
I am attempting to create a circuit with the following characteristics. I need a light to remain illuminated, at full voltage, then turn off when it gets dark. I know that's not normally what people try to do....but I need the light on when its light and off when its dark.
I created the following circuit and it worked with one exception. As you can see I used a 9v battery but the output to the lamp was only 3 volts. I need the lamp to be at full power (9-11 volts). I would appreciate any help I can get. I didn't have the transistor listed in the schematic so I used a 2N3904.
Would you recommend different resistors?
Would you recommend a better circuit?
Maybe something with a relay?
Thanks in advance for your assistance.
