Here is simple steps to convert your Rechargeable Emergency CFL light to LED  for  just 1 $

converting CFL to LED it can work up 8 to 10 Hrs. and you will be saving total energy of 75%.

Step 1: Step 1. Material

Existing emergency light , I had is SUNCA rechargeable  cfl light with 6 volt 4.5 ah smf battery. 2 x 6 Watt CFL

1.Power LED 1 Watt  with heat sink  - 5 Nos  x 10  =  50  Rupees
2.Resistance 10 Ohm  5 watt or 4.7 ohm 5 watt for more brightness - 1 No. x 5  =  5 Rupees

total cost is Rs. 55  in India , around 1 $ in US

Step 2: Step 2 - Circuit Diagram

Make the changes in wiring as shown in Circuit diagram. Radio, cassette player kept as it is, only CFL power is disconnected. and Bulb & 2 CFL has been removed.

Step 3: Step 2 - Assembling

Solder LEDs carefully , LED are heat sensitive , connect wiring as shown in circuit diagram.  Apply little glue to LED heat sink base to fix LEDs.

Step 4: Step 4 - Finishing

After completing wiring check for dry solder loose contacts etc using multimeter . Then switch on Emergency light to test the LEDs are working fine, then close the acrylic cover .  Now here it goes Live.

    Wow, I had no idea you could make one of these yourself. You have some pretty easy-to-follow instructions on here too. I've been considering starting up a tow truck business. I would definitely need a lot of these lights for that. I could probably save a lot of money if I could make them or find them at a cheap dealer. The light you have on this post isn't exactly what I need, but there are some on this site that are similar to what I need: <a href='http://www.ledqusa.com' > http://www.ledqusa.com</a> Is it possible to make lights like this?
