the A/B strobes on 1/32 power should hold up pretty well and at that power they will have to be diffused quite a bit At the aperture you are using.
Paul C Buff has always had a great warranty and Customer service.

Would you be willing to try one of your A/Bs at 1/32 power for 150 flashes at minimum recycle time, and tell us if it survives?

Thanks Manglesphoto. I'm going to check the specs on the Alien Bee's. Most of my 10X stacks are between 50 and 150 shots, sometimes more, with 5 micron steps. I'm currently using two daylight LED bulbs but my shutter speed can sometimes be several seconds. Even tho everything is on a concrete floor I think I'm seeing some camera or subject movement. I want to get the shutter speed sped up a bit and am hoping a 110 strobe might be the answer.

At 10X, you might need steps even smaller than 5 microns. I would worry about firing the number of shots required with no cooling off period. If overheating doesn't shut it down, would not the color temperature change as the flash tube gets extra hot?

Thanks. At 4X and 10X I'm using microscope objectives, finite for 4X and infinite for 10X. I'm calculating for an aperture of about f/4. It's the 10X shots that I'm having to use longer exposures. Just a truck driving by can cause some shaking I think, that's why I would like to switch to strobes.
At 10X vibration is a huge problem. Even on a concrete slab. The solution is to tie camera and subject as rigidly as you can so that they move as one piece. Then isolate the rig from floor transmitted vibrations by hanging it from long bungee cords.

Is there a "properly machined product" which will not have any play in the camera's hotshoe?
I am very happy with Astromania's Sight and adapter. The adapter is small enough to stay on camera when dot sight is not in use, and it's much more rigid than the thumbwheel style adapter. https://astromaniaoptics.com/products/astromania-for-the-flash-shoe-of-dslr-cameras-mount-the-1x40rd-reflex-red-green-dot-sight-to-dslr-cameras
I have a PMG L plate on my R5, and the vertical section has a flash shoe, so I put my Dot Sight on that. It puts the sight closer to the flipped out LCD so I can eye both better.

"I’ve used Costco and while results pretty good, I returned to Bay for best quality. I would be leery of CVS. CVS can’t produce a decent paper print. Cannot imagine being happy with metal. If I need aspirin, I go to cvs. If I want photos, I go to photo specialist. (Walgreens, by the way - same thing)."
Easy to return for refund at your nearest CVS. Try one, I think you'll be pleasantly surprised.

CVS, Big Discount sale before sale ends Saturday. Good quality and packaging. Nice Acrylic Panels, too.

I had one of those in the parking lot where I worked a long time ago. Funny, about that time I worked for a Fiat dealer and those were new, early 70's. Thats a Fiat 850 Spyder.
Actually that one is a 1968, they got headrests built into the seats in 69.
I ran a Fiat, Alfa Romeo, Rover, and Triumph new car dealership in 1969.

He's a Doctor! His bills are always considered to be too high by his patients. He's used to accepting lower than billed payments from third party payers. Psychologically, he's "projecting", expecting your thinking to be similar to his own.

Qimage is a program for windows that will let you schedule maintenance prints. It will also let you purge only selected colors.

I run a little program called InkJet Plumber. It runs at preset intervals (5 days for me) and prints each ink as a solid square and as a fine line pattern.
Almost never need waste ink with cleaning cycles.
