Thanks for doing that Paul. And ignore the gripers. What you described is fairly common in an engineering environment. It's better to isolate problems early because if you have to fix them in the field, it'll cost anywhere from 2x to a magnitude more (I've been sent into the field to debug problems and that's even more expensive)-: to fix, not to mention the marketing damage it does, and a lot of people don't realize this...
Been doing some testing here , I set a Pocketwizard MultiMAX intervalometer to fire trigger my Einstein 1800 times, once every 5 seconds. Except for the occasional thermal overload prevention kicking in , no problems. When the thermal overload circuit is triggered there's about a thirty second break between flashes.
In the event the thermal protection points prove to be to aggressive or conservative in the field they can be altered by SD card firmware upgrade. Ellis, it sounds like they are about right as shipped if you were at full power.
Thanks for the clarification. I know that I am not an early number, so I will bide my time in eager anticipation. Unless of course Ellis wants to sell me his used one today
I have to ask, maybe bacilonur, Paul or anyone more intelligent then I can fill me in! How in the devil are you running 640 watt lights off of a 180 watt inverter? I realise it probably has a peak of double 180 watt but that is still around half of the light watt seconds...!? I'd like to make one myself but this has me beat.. Does it have to be pure sine?
some of weird you people, say about Paul whatever you want but i would love to have such direct and family like contact with my favorite flash/accessory manufacturer. Too bad here are everybody too "business like - ie not even answering emails very often and everything nonstandard is a nogo" and PCB dont have distributor in europe.
Basically filling a bucket (light's capacitor banks) with water (stored energy) from a tap (your inverter) and then up-ending it when full (triggering flash) vs running said tap continuously. Higher the water pressure & pipe diameter (inverter output capacity), less time to fill bucket.
Since a recharging bank will suck all the juice it can get (assuming not set for a slower recharge or otherwise limited to avoid tripping breakers - see below), larger WS inverters also have to work less harder and should (all other things being equal, which they never are) stay cooler in continous use. Cooler with electronics = better for longevity/NOT blowing iffy components, avoiding surprise bonfires, hanging around waiting for gear to cool down prior to packing after a shoot, etc.
Some large WS packs, if dialed up to 'nuke it' power and not set for slow recharge, can trip normal household circuit breakers, especially in older homes and/or if other lights/appliances are on the same circuit as they simply try and suck more power (amperage) during recharge than the circuit can safely deliver.
Bear in mind the WS rating is the stored energy in the light - how effectively that translates into light output (bare bulb) can vary by manufacturer (for lights of same WS ratings) -- and then 101 variables after that.

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.
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. ...Show more →
Nothing inaccurate was started by me. You are the one comparing the Zeus to a IGTB pack in the first place. NOT ME. Did you not write that Zeus was 1/300s and the Scoro does only 1/85s? In fact the data on your web site for a regular head shows 1/260s not 1/300s for the Zeus (confusing and not consistent). Back to topic, all I do is ask you about how short a flash duration the Zeus can do. All you do is bring it back to comparing the flash duration in non IGTB context at MAX POWER and max power only. There is no mention at all of what Zeus shortest duration truly is. And how hilarious and again inconsistent that you bring higher WS into discussion since you did not build the Einstein with more WS specifically because, as you say, most photographers DON'T use higher power.
Your true facts only come with selective data. Read your posts, you bring up “10K Euro packs” to compare with Einstein, and now the “apple to apple” comparison of “much more technically comparable” mono lights. Something don’t ad up! And by the way if you did read my posts you would have noticed that I’m well aware that you can’t get full power and fastest duration at once on the Scoro. My experience is with 1600ws packs. What I wrote: “Under around 1200ws, the pack start letting you manually overwrite the flash duration. The lower you go, the more control and you don't have to go all the way down to lowest power to get full max flash duration under your fingers”. These are true facts. Nowhere do I combine full power and fastest duration. Your 3200ws with 1/8000s at full power is a totally made up story coming out of the blue (voodoo). The only true fact about it is that you came up with it, no one else. State the true facts as I have done here… There are not many posts on Scoro and flash duration out there and I don't see how you can't count them. Please do me a favor and post all those links, I'd love to read them all.
By the way thanks for welcoming me to post about your product on someone else’s forum. That’s truly impressive.

You could have just posted a one liner.
I looked at this a while back. The Zeus packs are will get their shortest duration at *full* power, so that number is what you get (1/260 you said?)
However, you can hook a Zeus head to a dynalite pack which is designed the other way...lower power = faster duration. Run it at the lowest power level (don't use the variator or you'll increase the duration) and you'll get the fastest for that, though it's still typical studio head "fast" unless you do the quad tube bi-cable thing to get it to go faster...
the t0.1 for the 3200joule Scoro A4 at full power is 1/132nd second
The Scoro A4 Broncolor's own literature is a bit confusing as they also list t0.1 times ranging from 1/85th to 1/8000th second but does not connect these numbers with energy levels.
The t0.1 for the 1600joule Scoro A2 at full power is 1/265th second
And as is the case with the Scoro A4, the A2 pdf also lists a t0.1 flash duration range (from 1/150th to 1/8000th second) but likewise fails to correlate these numbers with energy output levels.
With the standard Z2500SH (this is the standard Zeus head) with the Zeus 2500 w-s pack the t0.1 @ full power is listed as 1/260th. for the Z1250 pack and the same head the t0.1 times are not listed. If you switch the Z2500 into Assymmetric mode ( 1875w-s to , the t0.1 duration for the same head on channel A (1875 w-s) is 1/350th second.
Again, these are factory supplied numbers for the two Broncolor Scoro packs and the Zeus Z2500 , all with standard heads.
Enjoy 'em Patrick! But if Paul Buff's conservative politics turn you off ( and I can't say I blame you) you might consider going with Profoto or Dynalite instead. Just sayin'.

Thanks e-vener and particularly conner999 for your descriptions, I understand now. Appreciate it.

Yeah, that's part of it... it's also the way he went about it and the tone that makes it difficult for me to give him my hard earned $$. Everyone is entitled to their own opinion, but after what I just read, I don't think that I can support him. I'm sure they are great lights though.
