Crudely measured, the Einstein in color mode at full power is recycling in 2.0 seconds +/- 0.1 second.


Either your line voltage is way low or your measurement is off. Einstein cycles to full power in 1.7 seconds at Color or Action Mode at 120VAC or 240VAC input.

You mean the 8 pins?

Jeez, you are right. I haven't looked at the CyberSync CSXCV since I plugged it in to the Einstein last week. It is 8 not 4 pins.

Seems likely. and as i said it was crudely measured.

Ellis, film the back of the Einstein with your iPhone, noting the green light.. More accurate than hitting the stopwatch.

Don't have an iPhone 3Gs , just a 3G. Hey wait! I can do it with the D3s!

Result: Full power recycle on the Einstein is clearly well under 2 seconds.

But I'll have to open the vid in Premiere Pro CS4 to get a fractional second time readout.

Wow, that really is tiny!

Does it have the selectable channels on the other side, or do you select channels through the Einstein?

The iPhone camera is a better idea. A stopwatch doesn't work well because the eye response from ready light to stop watch will invariable give you a falsely long ready. I use an oscilloscope and can assure all it is 1.7 Seconds. Now if your AC line is 115 instead of 120V it will get longer.

. Someone seriously has to limit the number of toys you guys have
This is getting as weird as "how many engineers does it take to change a lightbulb?"

25, but that is only on the initial design team.

What size of a bulb are we talking about here? I mean .... it does make a difference you know!

For the SCORO 1600ws at 8K here is the link you COULD NOT find for some reason

http://www.bhphotovideo.com/c/product/599748-REG/Broncolor_10_2990_Scoro_A2S_1600_W_S.html
I would get checked for selective reading if I was you, that was pretty easy to find...

The Zeus, you omitted to post it's shortest duration 1/900s VS 1/8000 for the Scoro As you say what's the difference, just 9 time faster after all... There are plenty more details you omitted, but you know that too...

I'm well aware of how flash duration works with Broncolor and I own packs. I'm interested in the Einstein for other reasons, and I understand well it's limitations

Ox goring is not a pretty sport. Broncolor makes very nice, very high end gear. It is at the peak of high end electronic flash gear, just like Profoto Pro 8, Briese and the very best of the Balcar, Elinchrom and Hensel lines.

The Zeus is a middle market system in terms of features and light quality. Also in that range are Dynalite, Profoto Acute 2, Speedotron Blackline, a lot of Hensel, Elinchrom, Comet, and Norman 900V systems. All of them are workhorses , and all of them have features the others lack and lack features the other ones have.

I wrote about what was being discussed, which was a statement that Scoro could be set to whatever t.1 you want and the oft misunderstood implication one could, at the same time, set both the t.1 time and the WS. I can't count the number of posts I've seen that say "Scoro can do 1/8000 t. and any color temperature you want at any power you set it to." This is pure hogwash and ignorance and/or misinformation. I'm not knocking Bron - just setting facts straight.

You launched into an attack about what I didn't post and that somehow I was withholding or evading something, and made the ridiculous implication the Scoro is 9 times faster than Zeus. Sure, Scoro is an IGBT system and Zeus is not (nor is Dynalite, Speedotron or any number of other packs.) In fact the core full power t.1 duration of Zeus at 2500WS is 3.5 times as fast as the core full power t.1 of Scoro 3200 WS, and twice that of the lower power Scoro 1600. The core t.1 of Einstein at full is 1/600 and the minimum t.1 at low power is 1/13,500.

On a more apples to apples comparison (Bron Monolight to Buff Monolight) the Bron Visatec Logos 1600 600 Watt/Second Monolight (120V AC) has a full power t.1 of 1/200 and a minimum power (1/16) t.1 of about 1/120, and a color shift of about 300 . A non-IGBT 640WS AB is about 1/650 t.1 at full and 1/400 at 1/16 power at an essentially identical color shift. RX600 is virtually identical to AB 640WS model (AB1600) in these parameters.

Einstein has a 1/600 t.1 at Full and 1/4000 t.1 in Constant Color Mode or 1/10,000 t.1 at 1/16 power in Action Mode.

I suggest if you want extremely complete info on Einstein, go to http://www.paulcbuff.com/pcb2009/einstein.html and click "download manual".

For those interested, here is link to Bron Visatec 600WS monolight specs and price. http://www.bhphotovideo.com/c/product/316156-REG/Visatec_51_051_00_Logos_1600_600_W_S.html#specifications

Maurice, you, along with anyone else, are welcome to write about Einstein anytime you want. But I would check your bias and smart remarks at the door. State the true facts as I have done here.

I think we are getting a bit o/t here. This thread was supposed to be a review of Einstein which is what I and I would think most people reading this thread are really interested in.
