This is an easy to build "high-bright LED" night light, which I was design and developed in weekend to replace my existing 5W (filament base) night lamp.
This circuit is mainly based around TL494 PWM driver IC and LM350 - 3A adjustable voltage regulator. The LED used in this project is 9V - 10W high bright LED and this given design is capable to drive maximum of six, 10W LEDs.

This unit is design to work with 12V to 30V DC power supply and it can withstand for voltage fluctuation around 12V to 35V.
