This teardown of a current dollar retailer example reveals that value-slicing has managed to shave even more off what was already looking like a market saturated with backside-greenback design. The electrical components inside this glowing model of value-chopping consists of one PCB (beforehand-seen greenback store LED bulb examples had two), eleven LEDs, one bridge rectifier, two resistors, and a controller IC. A wirewound resistor apparently additionally serves as a fuse, simply in case. IC to see what lurks inside, and the result’s shown here. One hundred Volts DC that the bridge rectifier and huge electrolytic cap present to it, and it’s both cheap and clever in its personal way. The top half is a giant transistor for chopping the voltage and the bottom half is the simple control logic
