    I love this but I need it to run some 12v LED lights. Any suggestions?

    well done zhyar, Try attaching a variable resister so that the sensitivity can be controlled.

    sorry I didn't understand can you elaborate your words ! what is ttls ?

    That works with only one transistor if you've got a load with a relative high impedance, such as a Led.

    I tested it with one 2n2222a transistor and it worked but it wasn't so efficient and the LDR was not sensitive also the LED wasn't Bright . so I decided to make it with two transistors and as you can see in the video the results are perfect
