The definition of the beam angle (FWHM) is half view, which defines by Energy Star, 50% light intensity.
     The definition of the beam angle in Ledlink is in full view, which is 90% of light intensity.
     Please refer to figure one for reference. There are three colour of curves in this figure, the half angle
     of these curves are the same, which is 30°; however, the beam patterns of these three are slightly
     different as the full angle of curve A is 80°, curve B is 60°, and curve C is 50°. For example, the feeling
     of the beam pattern A is more uniform than beam pattern C; but the beam pattern C will be brighter than
     beam pattern A. Ledlink would like to enable our customers apply our products more accurately to meet
     their original expectation.

Yes, we can do custom design according to your demands and we do it by our (12) optical engineers;
     and the total lead time from the design to first trial shot product is within 30 to 45 days. If you are in
     urgent, the lead time can be reduced within 20 days case by case.
     (a) We will provide you a simulation report which generates by Fred or Tracepro within 7 days after get
           your confirmation of the requirements.
     (b) After have the confirmation of the simulation report form you, we'll start to process the tooling and 
          provide you the first trial shot product within 28 days. At the beginning, there's only one cavity in
          your custom tooling as the product hasn't been approved. Once we have your approval of the T1
         (first trial shot) sample, we'll start to do the clone process to either two cavities or four cavities, this
          depends on the situation.
     (c) We will be responsible to meet all the requirements which we have discussed with you.
