Hacked LED Flood Light. Start Up Project 19


16AOnce I purchased a 10 watts LED Flood light for Rs. 450. The Ad was so attractive that it is capable of giving light similar to 40 watts Tube light with low current consumption. But the result was disappointing. So hacked it to see the power, current and voltage consumption. It is a 12Volt 10 Watts LED Flood light as mentioned in the pack. The result was very interesting. Nothing matches with theory, specification and real measurements. Generally, the 10 Watt White LED works on 12 V DC and requires 500 mA to 1 Amps current to get full brightness and Flood light effect. It has around 10V Forward voltage. It is usually powered by a high current LED driver that delivers 500 mA to 1 Amps current. Here comes the reality. Many LED flood lights use low current LED drivers or Capacitor power supply. LED Driver is a small SMPS with an output current rating. It must match with the current requirement of the LED. Cheap Capacitor power supply can give only 75 mA current per uF. So we purchase the lights by looking the specifications on the package and not realizing the actual condition of the light. To experiment with that Flood light, opened it to see what is happening inside.Secret revealed.
