I have this half watt LED night light with photocell. The problem is my bedroom has dark drapes so the led stays on all the time. I only sleep in my bedroom at night so I want to maximize the life of the LED. Here is how I externally mounted the photocell or light sensor.
Removing it's single screw, the case came apart and the sensor is accessible.
Step 2: Soldering an Extension Cable.
Using my soldering station, I removed the photocell and attached a 2 core cable to the circuit board. I soldered the photocell to the other end of the cable and applied liquid tape.
Step 3: Fitting It Back Together.
The extension chord I passed through the window where the photocell originally was. The sensor I secured to the burglar proofing at one of my bedroom windows.
Now the light only comes on when outside is dark.
