I got asked to create a dimmer for a Filament dim-able LED (AC 220-240v) Bulb (several of them actually), and i so a looked at doing a zero-crossing detecting circuit and then driving a TRIAC circuit as explained in this instructable, But when i started measuring the bulb (3.5w) i found that only in…

Come to think of it, aren't these bulb running on half-duty-cycle for starters ? half duty cycle.JPG
