Absolutely not. Einstein is designed to work with Vagabond and never reset unexpectedly.

This just keeps getting better and better!

Hi Paul I too am in the snow world on the ski side. Will the Einstein have massive venting like the AB series has, along with a constant cooling fan? Working outside in some rather hostile Winter conditions, the venting is another issue, as well as the cooling fan going at all times, drawing more power out of the already high drain rate due to cold temps.

The Einstein has me quite intrigued as the weight and battery potential could be absolutely a huge thing for me instead of carrying around my AB's with modified vagabond packs and my ranger rx, especially when traveling. I very eagerly await the release of these.

Einstein will have more cooling capacity then previous models but the fan is uP controlled so will adjust speed as needed by heat conditions.

By the way, the fans in AB/WL don't really consume any power - they are used as a regulator element in the basic control power supply. AB/WL are very efficient in quiescent power consumption compared to other lights.

Awesome to hear. I wasn't sure about the fan but I figured in the cold, as much as -10f, it can't help. I'm really pumped on the idea of this. Being able to have a spare battery set of c sized batteries from wal mart as a backup is amazing. I'm going to Chile in a few weeks and am bringing 2 ab's with some lightened power supplies instead of my ranger because of weight. I wish I could bring these instead, sounds like same weight as what I'd be bringing only more power and better durations!

BTW is there a mailing list or something to get on so I know the day these are available?

One other thing, will the modeling light stay on as long as you want like the AB's?

You will have complete control of the modeling lamp. But you won't want to be running the modeling lamp continuously on batteries because they will drain batteries rapidly.

As far as a a mailing list for new developments that's a good idea. I'll have customer service start one tomorrow.. Just email info@paulcbuff.com and tell them you want to be on the New Developments mailing list

On times I'd need to run the modeling light though, I could just plug in a 15ah battery to it though. I've been running the modeling light in some situations off my 15ah battery. It is a really nice option to have to provide continuous light in situations where weight and locations prevent bringing hotlights and a generator.

We're getting a little ahead of the design, so I can't make solid promises on exactly what you can and can't do yet. But I can say a 15AH battery will only power a 250W modeling lamp for 20-30 minutes with no flashing.

it's not a problem. in those situations i've just turned the light on and off as needed to get the most out of the battery life. also using a fluorescent bulb to get the most out of it when i'm in that situation.

And that's one of the ways the radio remote makes the system shine. It's easy to turn the modeling lights on while you're looking through the view finder, then turn them off again, all without running back and forth to the lights.

I'm simply stunned by the specs Paul is discussing. The following is from another thread I started, before finding this one.

These recycle times would be absolutely stunning if they turn out as expected.

This leaves me with only one last feature request-

PLEASE make a good quality Elinchrom adapter. I’d potentially like to buy 5 Einsteins, but what do I do with the Elinchrom large octa, and deep throat 39" octas I already own? I can't give them up, they are special.

Why not marry PCB’s remarkable electrical engineering skills, with the expensive light modifying collections many photographers already own??!

Nikon just wildly extended their lead in on-camera flash, with the announcement of the SB900. Canon’s 580 II is a total dog (IMHO) Sadly, I can’t change because I own a lot of Canon glass, and am particularly attached to a couple of lenses that Nikon doesn’t have a replacement for. Light modifiers can be the same.

Offering adapters would also solve the issue of some people complaining that PCB foldable softboxes aren’t big/small/deep/tall/sturdy/don’t make coffee/etc. enough for them.

I plan to make Elinchrom to PCB adaptor - it's on my project list.

Thank you.

[quote="Luap"] Full power duration around 1/2000 t.5 and 1/1650 t.1. It has an action mode that achieves shortest possible durations as you dial down the power. You can expect around 1/2000 t.1 at about 500WS and as short as 1/10,000 t.1 in the 50-100WS range.[/quote]

Paul, first off, thanks for answering all the questions regarding the Einstein. And just to bug you one more time, I have a question regarding the above statement about Einstein flash durations. The full power duration is stated as 1/2000 @ t.5 and 1/1650 @ t.1 for 1024WS model. I was under the impression that t.1 times are generally 1/3 that of t.5 times (this is how the t.1/t.5 durations are stated for AB/WL). Is there something different going on because of the different technology?
