Hai all,
This is a simple instructable and I am going to share you how I made this little DIY to make a zero cost torch with a power bank. Following the simple instructions, you can make it easier.
Collect the Raw Materials.

For the project, you need:
- PVC pipe (small piece with diameter as per your wish, I used one with a small diameter)
- A dead CFL light bulb.
- A small piece of universal PCB.
- A white color LED.
- Wires.
- Push button switch.
- Push button cap.
- A power bank battery. (technically, A 18650 battery with 3.7 V 2200 mAh battery). (From old power bank)
- A 5 V DC boost converter. ( From old power bank).
- Aluminium foil.
- Thick paper.
Make the Body.

Making the body is not that complex. Follow the steps:
- Remove the top part of the CFL.
- Remove the cap of the CFL as shown in the figure.
- Now heat one end of the PVC pipe and join it to the CFL cap.
- For the reflection Make a cone using the Aluminium foil and the thick paper.
- Attach the LED on the cone as shown the figure.
- Cut some transparent plastic in a circle and attach it to the front of the LED.
Now the main body and the front reflector are ready.
Make the Switch, USB Part

For the switch and USB,
- Mark on the pipe, as shown in the figures.
- Cut the portions for the switch and the USB port.
The Circuit Part.

The circuit part is simple.
- Solder the battery to the boost converter.
- Solder a red wire (+ve) and a black wire(-ve) to the USB port of the Boost converter. These wires provide the power needed to light the LED.
- Insert the battery and the boost converter into the pipe and fix the battery using a double-sided tape.
- Fix the USB port in position.
- Take the wires out.
The Switch...

You can use spray paint for the finishing work. I used some black stickers for the purpose.
We can recharge it using a smart phone charger and this can be used as a torch and as a power bank.
Thanks for your time.
Happy making.
