You will need below parts

20x 5 Watt SMT leds

1x Voltage step down Buck converter

I used a 3mm thich 8.5 inch aluminium utensil lid

thermal grease

Mains cable wires

toggle switch

20Volts 3Amps Laptop power supply

I cut a 4 inch diameter circle in aluminium lid on a lathe machine

sanded up the sharp edges with a sand paper to smooth the sharp edges

took the 5 watt smd leds applied thermal grease and placed it in circle.

took a acrylic piece cut a 4 inch diameter circle.

now after this if you want to replicate it the same way then need to use the exact measurement of your lens and then cut a circle inside so that it can fit just above your lens

With my luck I got the acrylic piece exactly fitting on my lens.

Once the leds are placed you need to solder place it in parallel

Positive & GND IN parallel.

recomend to use thick gauge wire and solder in

Please check this circuit Diagram for reference.

Connected the leds to variable power supply & multimeter to check the optimum voltage

with powersupply of 20 volts and connecting a buck converter to it it was coming to 11.8volts with 2amps current.

So once its done then need to take few rubberbands and stick it to the acrylic cutout like how i have done

recomend to use a spebb7 or epoxy glue or use hot glue(hotglue not much reliable).

and then connect the power supply.

So first thing I did is clicked some macro photos and turned out really good.

Can also be used for vlogging, video making, potrait shots

The Rig turned out really nice however there are few things which I noticed which I would like to tell you.

Heating because the aluminum lid was thin so the Picture what you see above is the second version of it in which I used a thicker plate ( Instructables for the ring light ver2.0 will be uploaded really soon).
