The MR70 looks interesting, with its side flood light and power bank functions. It looks like its beam is only about as throwy as a D4 though, and it only comes in cool white. I’m curious how its interface works, so I might look that up to see how they handled two independent LEDs from one button.
At a glance, here’s what stands out about them as compared to each other.
MR70:
Works as a USB power bank
Has a side flood light
3-4 output levels (low/med/high and timed turbo)
Strobe and SOS modes
Lighted button indicates battery status
D4S:
Smaller
Has lower low modes and higher high modes
Quite a bit more throw
Comes in a variety of host colors and emitter tints
Smooth or stepped configurable ramping from sub-lumen to full power
Adjustable momentary and beacon modes, plus voltage and temperature modes
Can be used for some tasks while locked
More mod-friendly for hardware or firmware changes
Personally, the mode I use the most on pretty much any light is about 5-10 lm out the front, ideally in neutral white with decent CRI. After that, my most-used mode is moon, at about 0.2 or 0.3 lm.
The Emisar lights give me exactly what I want there, with immediate access to both from off. However, the Rofis light doesn’t even have those levels. So it’s a clear choice for me.
I design my boards without undersized viases/smaller distanced between traces, very thin traces ect.,
which increses the production costs on chineese fabs, this makes it often more challenging to get it fit
First step without trimmers 32mm
33mm diameter with potentiometers and 3 separate channels
Lexel, are you looking for the smaller 4 holes in the 33mm MCPCB? I don’t have the D4S yet but I do have the boards and I do have a working X6 using this board. About to head to bed tonight but I can get measurements on the inside ring of 4 small holes if that’s what you’re looking for…. I get 20.0mm across center to center, so 10mm from center of board to center of the small inner circle of holes.
I should point out that this is using a set of cheap plastic calipers’, my good ones are out in the shop on the lathe…
