Brother Can I use for 10 watts tubelight not bulb

[peymanamiri]

Its good but dosent have good light becaus dosnt have good current.

[ashokkulkarni]

सर, आपने इतने सारे सर्कीट्स बनाते हो मैंने यूट्यूब पर हमेशा देखता रहता हूं.पर मुझे कृपा करके ५ वाट एल् ई डि बल्ब का सर्किट बनायिये मैं इंतजआर करता हूं.धन्यवाद सर..

Can we use this circuit for 24 watts street light.

[kennmossman]

this is BS. Max practical current is about 100mA, so you are lucky to get a few Watts*. The input cap determines the current.

Furthermore this is a DANGEROUS circuit - it is mains live.

*you will NOT get max brightness unless the LEDs are operated near their rated current which is very unlikely with this circuit.
This is a dismal copy of a standard circuit - done and presented without any knowledge and understanding.
