Emisar D4S review

Dale clearly hasn’t shopped for lady toys. :stuck_out_tongue:

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
  • Front-facing aux LEDs
  • Optional tail magnet
  • Lower price

Looks worth having. Not sure about the MR70.

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.

But YMMV. Different strokes for different folks.

I’m between this or the Q8, decisions decisions.

You already know the best choice - BOTH!

D4s…

D4 and PL47 boards were the first 2


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

Nice work, Lexel! :+1:

Those boards are beautiful, even without power applied!

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…

Great stuff PBWilson appreciate the information and response. I may just have to get the shockli button tops then

Nice Job Lexel … :+1:

But why do I read there PL47 and Fireflies on the one design … ?

Can you explain me please ‘cause I’m thinkin’ about to get a second ROT66 (in 4000K HI :cry: ) but …

… maybe via PM ?

I saw someone posted D4S with red optics backlight? I only see cyan option at IOS.

Nice, I’d order a second light if red was available.

I was hoping Emisar would make a red backlight version. I am holding out until then.

As far as I have understood, those color-LED boards will be sold seperately in different colours?

Why not make a RGB-version, so people can set their preferred color themselves?

Ever notice how, when a manufacturer picks up the gauntlet and offers something new everyone screams MORE, you shoulda, you coulda, you oughta…… ?

Thank you Hank, well done! :slight_smile:
