What is probably meant is that the 7135 chips are orientated 90 degrees different from usual, what makes the thermal pads not facing the ground ring anymore and thus the heat has a worse path to the flashlight body.
Those 7135 chips are pretty tough though and I expect that they can handle this.
Maukka! Very nice beam shots and comparison! It’s really cool to open both pictures and click back and forth in full screen to compare….so cool to watch the minute differences in shadows etc. Looks as though the D4 beam is ever so slightly wider, which makes sense…but not much wider. Unless the angle of the lights was just a touch different when pics were taken (can see shadow of small twig on lower right in foreground move up and back just a bit…like the D4 was just an inch or 2 more forward than the FW….but again…probably just the wider beam of the D4).
I’m babbling…sorry…again…THANK YOU! Very nice shots and comparison.
I was joking lol, based on the discussion on what to call the Carclo and the glass pane in front of it… it was always planned to have a triple Carclo TIR optic and a glass window/lens in front for protection. So no, none of this discussion would drive the price up
