A New Bare Bulb Flash Arrives

I was shooting the 360 into the sun today, and I'm a little disappointed that I couldn't do f8 with ISO 100 about 7 feet away. Was able to get down to f5.6, but I was expecting a little more power at 1/1. This is with a softbox w/o any diffusion and the default reflector (also w/o diffusion circle), triggered with a YN-622C. On the Einstein, I'm able to do f11 easily.

Am I doing something wrong or is this expected?

Einstein is 640 w/s, AD 360 is around 300 w/s.

And should not be forgotten. There is a difference.

Yeah, I know that, but I remember Scott showing a meter reading of f9 and f10 at 7ft. with a couple modifiers. If I'm getting f11+ with Einstein, I should be able to get f8 with the 360, or so I was expecting since the Einstein is a little more than a stop brighter...

First, as noted, the Einstein is 640 Ws at full power.
Second, the H mode with the CL-360 offers long burn flash that is useful. The t.1 flash duration on the CL-360 is such that it can be used with FP-sync at any shutter speed, then with H mode enabled there is an additional 5 EV of range available.

I suggest that you spend some time testing the CL-360 in the sun. I think you'll find that its a useful tool once you become familiar with its characteristics.

Testing is actually what I'm doing. I'm trying to see what the limits are without going into H mode, staying within the 1/160 or 1/200s sync speed. Just wondering if what I'm seeing is as expected.

I'm not sure whats going on with your setup and what modifiers your using. I don't seam to have any problems with using my 360. Most of the time when I used my quadra setup I would only use on the average 250w. Again my lighting style is not everyone's taste. I'm a big fan of hard light and high output reflectors when I shoot. Stock reflector yields these setting with no diffuser and you want to take off 2 stops if your using a umbrella.

You will yield better results if your using the umbrella reflector in an indirect modifier or umbrella.

When I received my order from Cheetahstand I got a bad battery, Edward promptly sent me another one. I thought all was good , but Edward asked me to test it to his standards.

Here is the Edward test: 50 pops on full power as fast as it recharges. I could only get 32 (2 attempts) and it would fall into "Overheat safe Mode", Edward asked if the top part of the battery was hot and it was.
He tested a new battery pack and shipped that out immediately and a free 2 into one cable along with a shipping label to send back the two packs. All of this the day he received his last order and doing a trade show in Dallas!
So if your battery won't go 50 pops on full you have a bad pack.
Thanks again Edward!!

wow, good lessons,
I am gonna try my battery pack the same way also

Thanks Scott -- I remember seeing a chart similar to this that you had posted. I'm going to do some more testing today.

I tried this and I had no problem to get past the 30 and at 73 the overheat kicked in to time to cool the battery pack. The pack became hot at one side so I tried the unused connector to hook up the flash and I could use the flash again.

So it seems that you can go past the overheat protection by plug over to the cool side of the battery pack. I assume that side will overheat sooner because the the other side of the PCB is already heated up.

Thankfully, it was user error. I switched to my 6D to use the EOS Remote app on my iPhone and thought I had slow down the shutter speed from 1/200s to 1/160s, but either I didn't or I rolled back without knowing . With the stock reflector, I'm able to get up to f11 at about 7-8 ft. and about f8 with a softbox and a diffuser.

Do you mean ISO or shutter speed, because shutter speed don't effect flash exposure.
