18 LED Light Bulb for "extra" brightness !!

Step 1: How to Steps:

See my other two instructables for details on how to make this:

1. The AC Circuit Layout Version:


2. The AC-DC Circuit Layout Version, with a Diode Bridge:


Add triplets in series to get multiples of 3 for your light bulb !

Ketan! Bless you! That kid just looks like me when i was that young.And I AM playing with lights since that age!
Have a nice day! Do you have Yahoo/ SKype/ G Talk ID?

Does it fully lightens your room. Plaese can you show step by step procedure. Parts Used And Rating of LED.

Thanking You

My 2 suggestions:

1. Raise your competence to match your high aspirations - *mandatory* while working with 220V AC Mains !!

2. First try simple projects, like the ones below:


Sir i've already made a tube light of 30 led in series of 5mm LED. as guided by dipankar. But as it does not full lighting to the room thats why i asked help from you to please provide me with the drawing for making a powerful light with 1watt X ------- No. of LED or 3 watt X ------- No. of Led for providing sufficient light to the room.

Thanking You

Yours faithfully

Add 30 more in parallel with the existing 30. Use additional capacitor and resistor for the new 30. Connect both capacitors in parallel. Similarly, both resistors.

Clarification: Mr Dipankar's circuit is an AC circuit. It has mild flicker and he also clarifies it. I have used a diode bridge and made a DC circuit and so my circuit has no flicker (so it is brighter).

My AC circuit (with mild flicker): World's best LED Light Bulb - Part 1
My DC circuit (without flicker) : Part 2, as well as this I'Ble.

So, is that you in the picture?

Haha! Funny! Thats my seven year old kid.
"May the good belong to all the people in the world.
May the rulers go by the path of justice.
May the best of men and their source always prove to be a blessing.
May all the world rejoice in happiness.
May rain come in time and plentifulness be on Earth.
May this world be free from suffering and the noble ones be free from fears"
---- Vedic blessing
OH! Sry!

Nice instructable,
maybe you could provide the schemeatics of the Bulb.

How did you calculate the necessary components ( LED / Diode / Capacitor ) ?

Many posts, especially on this man's I'bles: dipankar

"I have intentionally not put the final lighted pics!"

But a lot of people like to see how well the final product performs before making it.

Yes ! Different people react differently ! I guess I will have to put it, so will put it up shortly...
