Either we have different strobe designs, or the Xpro is enabling this hidden feature with decreased output below 1/16.
BTW since I had my light meter out, I couldn't find it when I did the voltage testing way back last year, and it somehow reappeared
I ran some quick tests to see how these strobes followed the exposure settings with the meter.
The L-308DC is an integrating meter so it measures the area of the exposure flash waveform, which I had suspected changed with settings (why I mentioned the oscilloscope to view the waveform). The overall effect is to make the Studio 300 Strobe follow amazingly well from 1:1 to 1/16 settings.
The results were 1/1, 1/2.00, 1/3.91, 1/8.12, 1/15.19!! Not bad for a $100 300WS strobe with built in RF trigger!!

Seems pretty darn good for a $100 strobe to me. All of the specs are interesting but to someone like myself, I am totally satisfied if I can select a setting, take a shot and think, OK, that looks ok to me. If it is .780 rather than 1.000 stop, so be it, if it gets the results that I am looking for. I can see where this attitude would be fatal for a professional or one that must duplicate settings for business purposes but fortunately, neither of those applies to me. I had enough of scopes, spectrum meters, level meters, waveguides and etc. in my working days. What knowledge I had of them and their intent was forgotten when I walked out the door.
I do appreciate you taking the time to offer your expertise and suggestions.
You bet, it's a great value IMO!! If you take one apart you will be amazed and what's inside from an electronics standpoint, and the quality!! I paid $120 when they first came out, now they are $100!
I'm still working designing chips, this is very unforgiving business. A single simple mistake upon billions of possible very complex things can cost multiple millions of $ and you can't fix it without millions more, and must wait ~6 months after the design is finished and signed off before you can even begin to evaluate the chip in the lab! So I tend to dive into things more than most
Maybe someone else on here can evaluate these Adorama Studio 300 Strobes and report what they find?? Hint
Or send me a Xpro to evaluate
Since I had the Light Meter out I ran the XPLOR 600 & RAPID 600 thru the same tests. Here's what I got:
XPLOR 600: 1/1, 1/1.973, 1/3.982, 1/7.819, 1/16.21, 1/30.15, 1/62.06, 1/126.67 & 1/256.23
RAPDI 600: 1/1, 1/1.993, 1/3.879, 1/8.01, 1/14.7, 1/29.65, 1/64.16 & 1/130.15.
