what is purpose of 471k capacitor please tell can we used this circuit in making led chain of 60 led

awesome video bro

Nice broh

[@SolderingTech]

Thanks

Try using one of these and a bridge rectifier. iranmls.com/wp-content/uploads/2021/10/RM9003A-Datasheet.pdf. That does the whole job for just a few cents.

[@kennmossman8701]

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.

awesome bro

Thanks bhai

Can i use normal resistor here 1:24

[@SolderingTech]

Yes

[@motalibaluyodan8616]

What is the wattaģe of each resistor. Thanks

[@SolderingTech]

Input and output resistors 15 ohm and 1 ohm resistors are of 1w and both 470k resistors are half watt

[@mirmetch1]

How you calculate the output voltage to the led

[@gurkansen6009]

hello. which diode did you use ?

[@SolderingTech]

4007n diode..

[@gurkansen6009]

@@SolderingTech thank you bro

[@peymanamiri7560]

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

Brother Can I use for 10 watts tubelight not bulb

[@SolderingTech]

You mean for cfl this is not for tube light first video on my channel d882 transistor inverter 3v to 220v you can run any cfl/tube light with that circuit...

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..

[@kennmossman8701]

you need to be more deyailed......what is the supply voltage....dimmable.....efficiency....simple or what

[@saimanojnetha]

Can we use for 30watt led

[@SolderingTech]

Yes

[@kennmossman8701]

NO@@@@@@ this guy is full of BS. max practical cuurent is just 100mA You would be lucky to get a few Watts

Can we use this circuit for 24 watts street light.

[@SolderingTech]

Yes brother...

[@roshanjayasinghe4505]

Can use 5w, 7w, 9w led bulb

[@SolderingTech]

Yes you can use for any watts leds
