TK's Emisar D4 review

[Agro]

@maukka

Here’s some scope shots of the output. Measured optically OTF. Most of them links not to clutter the thread too much. Used a slightly discharged 18650GA and there probably was some throttling going on.

First on the 7135:
Moon

A bit above moon
A bit more
Almost there

71350 100%

Changing ranges:
Flashlight off

7135 100% for reference

Just a bit above
Just as specified, the higher range cycles between 7135 100% level and up.

Getting brighter

A bit more

Reaching some sort of a peak

Duty cycle increasing
Just a bit below turbo
Turbo

Maukka…
In another thread I mentioned how the driver seems to be acting as a current limiting device. Though in theory a FET driver shouldn’t behave like that. Kiriba-ru questioned that.

Also, I dont think output voltage from light meter is proper value to measure (for this discussion). Led have some delay but sensor also have some delay.

Any info on this FJ33 EDC?

Did maukka tested 8+ Amps 100% pwm+1 mod? Did maukka tested any leds after hard fet usage (I mean regular maukka color test, new 80 cri xpl vs used at 6-7Amps xpl) ? Also, I dont think output voltage from light meter is proper value to measure (for this discussion). Led have some delay but sensor also have some delay.

What do you think about that?
