Here glad to tell the common cases- the optical lens we did, Types I, II, III, IV, and V compatible LEDs 3030.3535.3838.5050... for Area & Site Lighting in different applications- parking lot, sidewalk, street and so on. With a lot of the experience, we are fully open to offering our technical support. 
Certainly, we are good at common cases and love the challenge too. My team and me waiting for the opportunity from you.
