  placing the led

  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.
