Well on mine it absolutely are since the head and a focus lens is right after, guess its the same on weartronics.
weartronics: i have now read through your thread and there some interesting info for sure, especially about the PSU. It seems like you dont know the output from the laser, dont know if this could help but mine are 180W CW and if i recollect right so is the lamp 32A or 35A 219V. Cant find the box for it though.
Here some other pictures if any is interested. Might open the rest up later cant find the right screwdriver right now.
