Appears my S41 And S41s do not have the Exact parts as M4D M4X. Are those both current production? Pre-Production Samples?
S41 with the red MCPCB looks like my First S41. Second S41 had the White board. My S41S is slightly different too.
Left S41 You can clearly see the Legs do not align with slots in MCPCB, My guess is they attempted to have them sit on Top of the MCPCB but forgot to factor in the thickness of the emitter.
Right S41S with obvious bend in the Leg of optic and tight against the emitters. This has been apart for a couple days and has Not been reassembled. Bent legs are as I took it apart.
S41 slightly squeezed together.
S41S Slightly squeezed
And an obvious twist in the Leg from over tightening at the Factory.
While there were changes intended to improve the design it is still a flawed. Optic, IMO, the legs are too thin and there only being 2 legs. While sitting the optic on top of the emitters I can feel a slight squeak as the domes enter the holes. They are an interference fit, Zero clearance.
Sorry for the cell phone pics and poor lighting. I do not have a Photo Studio. And the Workin Man’s hands.
