This file contain a base and 12 LEDs (6 on and 6 off) with high precision mesure.
The model in .blend file contain also materials realized with blender as rendered and modifier on fly. The other file format contains only the models of LEDs with modifier applied, for a correct scale remember that LEDs mesure 8mm in height and 5mm in large (6mm at base of bulbs). All component are named and separate but grouped to an empty axis so you can move the empty to easy position of all LED in the scene.
If you want recreate the material with other engines, remember that resin coat have a IOR of 1.50~1.55 but i don't use some textures or other maps images.
I hope you like it.
