IN THIS INSTRUCTABLE I WILL TELL U HOW TO MAHE AN EFFICIENT LIGHT CONSISTS OF LED'S THAT ARE COMMONLY RUN ON DC CIRCUIT.
HERE IT WILL WORK ON 220 V AC FROM GRID
POWER CONSUMPTION IS 7 TO 8 WATT
AND ITS TRANSFORMER LESS.

COMPONENTS:
• Capacitors 2× 0.47uF 275v AC
• Capacitor 1× 10uF 400v AC
• Resistor 1× 10Ω 0.25W
• Resistor 1× 1MΩ 0.25W
• Fuse with holder 1×200ma
• 50×Led’s white 5mm

Hardware and tools required:
• Cable Duct 25×16mm
• Hand hack saw
• Soldering iron
• Drill machine
• Wire cutter
• Steel ruler
• marker

7. Solder all other components according to circuit diagram and place them in bottom of duct use 200mA Fuse instead of 1A as in circuit.

Step 8: STEP 8

RUN THE CIRCUIT.

BECAREFULL WHILE USING 220V ITS DANGEROUS IF U ARE NOT PROFFESIONAL
I AM NOT RESPONSABLE FOR ANY DAMAGE .

Well it's a risk i prefer not to take, because one day someone else who has less knowledge may be messing with it.

The comment about parallel leds was meant more the moment when one led dies. a configuration like http://www.circuitstoday.com/mains-operated-led-lamp is a bit easier when looking for that one dead led.

But I like the end result of your labor :)

If you don't understand why this circuits is very dangerous don't build it. [hint: galvanic isolation]

Wouldn't it be better to wire the LED's in a parallel configuration?
parallel would most likely require the use of a transformer.
defeating the second sentence.

by running in this configuration you get pretty darn close to required voltage to each led right from the power line.
220VAC reticified and divided by 50 led = ideally 4.4 volts(220 can range from 200 to 240 volts) which is just about exactly what some of the more powerful bright white leds require. This means you only need the one minimal current limiting resistor. Parallel running circuits require not only a transformer to get close to the correct voltage, but also a current limiting resistor for each led(or series of leds, if run in a parallel/serial configuration)

Isolation would make the circuit much "safer" but we're makers, and accept certain risks when doing it ourselves.
That being said, make sure if you make one of these, to only plug it into a GFCI outlet. And make sure your cable duct is plastic. that will help provide a margin of safety, since there will be no exposed conductive materials.
