Solid State Tube Light Choke

The advantages of tube light over filament bulbs are well known.But these tube lights have problems too.They refuse to work at lower voltages,they are costly,burn out easily and so on.So,presented here is a unique solid state electronic design.

The circuit is shown in schematic a it uses two capacitors and four diodes and work along with a 100 watt bulb.The tube lights operated with this choke were found to work at voltage as low as 120 volts(in the 220 volt lines).The circuit provides a pulsating voltages to the fluorescent tube light fixed on a conventional stand.
