Waiven RLT collar

Hi guys,

I have read that there was a company which patented a special collar design to collimate LED beam to make them like "thick beam laser" but it has ceased operations 1 year ago and a kind of patent troll company would have purchased patents in order to stop others from producing these devices.

| RLT? LEDs

Does anyone have a spare collar of a such design bought previously which could be tested with Phlatlights 54/121 I have?

Thank you.
