Report to POTN members:

CL-600 first batch arrive on July.I find out something need to improve,Only sell to 5 customers.
On August,we find out we can not use "Xenergizer" so we have redo all the Battery pack housing,ETA 9-30.
10 days ago,I find out need to redesign the main board,so this push back again to ETA November...........
Sorry about all these happen.
We do not put our name on the product until pass our standard........
Hope all this worth the wait.
Thanks to Adam,David,Jesus,Rob and Scott trusting us and run the test for this new baby!

Excellent news!!

Mine are still pumping along just fine, but the new improved versions I hope are better.

I've been using an rs600p for the last month now and must have shot close to 3,000 images with it and haven't encountered an issue. Will all 'V1' units eventually encounter the same fate with these issues?

Hey Scott, do you know how the recycle time on the CL-600 compares to the 360 and 180's? I'm wondering if these would be any good for wedding or event/sports. Would you use these like one would a ranger rx as/s (freeze action + balance with daylight)? I've only read about hss and long vs. short flash duration for strobes, but I'm not sure if I completely understand it all just yet.

at 1/1 power on the 600 recycle time is about 2.3 which is about the same as the 360 using a 2 to 1 cable and at 1/2 power the 600 is about 1 sec.

I find the HSS/Fast sync not to be reliable, some times it works and other times it don't, but the 600 was not made for that.

Every system has its pro and cons and the key is learning them and taking advantage of those faults.
Weddings the 600 will perform well, but the size can be a issue with some people. Sports the unit will work great in a gym, but it will have problems freezing action if the ambient light is really strong. Even the Quadra A heads have the same problem with blur due to strong ambient light. The flash will freeze the action, but the ambient light will cause the blurred motion.

You can freeze action with slow shutter speeds even at 1/25 sec and lower as long as you can control the ambient light. HSS controls the ambient light as well as ND filter you need a lot of power using either way. The main thing is how close you want the strobe or modifier to your subject or in your frame.

Aluminum? Mild steel?

Is it as simple as drill and tap?

I just use a piece of 5/8 rod for 3 bucks

I use aluminum core round stock lightweight/easy to cut/easy to drill and tap/wont rust/

Remember that HSS, Hyper Sync or H mode on the CL/Godox strobes turns the light(s) into constant light source so the shutter speed is not the determinant for action stopping.

The intent, with all three options, is to extend the strobe output so that it is illuminating the subject for the full duration of the shutter travel. Also, remember that even at 1/8000 shutter speed, the time required for the shutter curtains to traverse the sensor is approximately the X sync shutter speed.

So, if X sync speed on a camera is insufficient for stopping motion, then HSS, HyperSync and H mode will not stop action either.

i don't see how that could possibly be true.

Yes the shutter takes longer than 1/X000 to cross the full opening but any given point on the sensor is only exposed for 1/X000, or 1/500 or whatever, stopping the motion.

I am not an action shooter but have just recently done some controlled experiments trying to determine what shutter speed i will need for an upcoming basketball shoot. I grabbed a ball and remote shutter release to find that 1/1000 almost froze my fingertips while dribbling, and 1/1500 did the trick, even at close range. I was using the CL-360 and i believe it worked the same with HSS or 1/1 long duration flash.

^^ My last sentence is poorly written.
What I was trying to say is that, since HSS, HyperSync and H mode are techniques that turn the strobe into a short duration constant light source, the shutter speed is the determinant for stopping motion rather than the flash duration since it is being extended to provide a relatively constant light source for the duration of shutter travel at x-sync speed.

I was kinda wondering if someone had hijacked your log-in.

The risk of making a post quickly and not rereading it.

The whole post is just wrong, not just the last sentence. Even though the DURATION of the shutter approaches x-sync the time the subject is exposed for during that time is only that of the shutter speed set.. hence, 1/8000s is 1/8000s and not the shutter DURATION of 1/250s. 1/8000s would be the appropriated "determinant for action stopping" and thats with each of HSS, Hypersync or even 'H' mode.
