Here is a quick video showing the size and some info of the CL-600 to the Quadra

http://youtu.be/eZwcpA​pFTJw

Will do a full video of just the CL-600 this weekend

nice job!

Sold. Nice video.

Any chance of seeing some sample pics taken at the faster shutter speeds from the 7D?

Really speedotron is alot of power for a good price

Ohhhhhh. I know. $1000 got me 3 202vf heads, a 103cc head, stands, and chimera soft boxes and a 2403cx. I know.

But guess which one is lighter?

What is the flash duration at the different power settings? Any action stopping capability with these strobes?

Must have not watched the video or read that I can shoot at shutter speeds up to 1/8000 depending on the camera being used.

I can stop action at 1/60 sec, but that's based on controlling ambient light more then flash duration. At 1/60 I don't need a ton of power and flash duration is always going to faster. I dout your going to stop a speeding bullet with out blur with this unit.

At 1/8000 you are in HSS have you done any testing with the 1Dx or 1D4? I assume light output is very low. I just wonder how useable this strobe would be for sports? Also what is the weight of the light and the pack? What is the price going to be for strobe and pack. I wonder how this will compare to the Einstein?

From the OP of this thread

Since this unit does not have HSS and I'm testing the unit on flash duration. Using both the Cells IIc and the YN-622c
I get useable images on the 7d 1/8000
I got useable images on the 1D mk3 between 1/5000 and 1/6400
I get useable images on the 5D mK3 1/2500
I did have to aim the head above my target focus point on the 5DmkIII to get a cleaner frame

This unit don't have HSS and your just tricking the camera to shoot higher then sync and capturing your image off the flash duration. Light output is going to very base on the distance between the subject to the light source. If the unit is over 8 feet away the unit is not going to even light the subject in HSS. Your going to need something over 1000Ws for that kinda shooting and a ND filter.


I own a 1D MkIIS and a 1D MkIII, so I can't test the higher then a MkIII. If I had all the versions of the 1D I would probably be using Broncolor.

I don't do sports photography or have enough info from you to answer that question. Each style of photography takes different gear. Models on location and studio work stuff, It will do everything I need and more. If your wanting a strobe unit for just sports and fast action then you might want to start looking at profoto gear.

The price is 598.00 for a metal case, nylon carrying bag, metal strobe head, and battery pack.

Your going to have to find someone that has an Einstein and CL-600 to answer that question. I'm not going to start a post war on which intermediate strobe company is better then another. Cheetahstand and Paul C. Buff both have great costumer service.

I think for the price, power, and a more reliable triggering system the CL-600 is the quadra killer.

Scott,

Really appreciate the video. Price seems very reasonable. How does the weight stack up against the Quadra? The heads in particular. I have to believe it's heavier but substantially?

Jim

The packs are about the same in weight. The total weight is about 9lbs and just the head alone weighs 2.5lbs. The flash head of CL-360 is 1.14lbs and the v860 is 1.4lbs with battery.

I will have to find a model the images shot at that time was just a black backdrop

Okay this is interesting.

Nice specs!

That spec sheet is slick. Good to see it is LiFePO4 battery.

What does 600 W/S (True 500 W/S) mean?

Also, I think there is a typo on the Power Adjusting line. I think 1/32 to 1/1 is 5 stops and not 16. Is it supposed to be 16 steps instead of stops?

Thanks for taking the chance and previewing the unit.

This light uses voltage controlled power adjustment. The spec sheet shows that flash duration increases a power is reduced. That is a characteristic of voltage controlled power adjustment. What Scott is doing is using Hyper Sync, Super Sync or whatever someone whats to call it which is using the flat tail of the power curve to illuminate the subject while the shutter curtains move across the sensor.

The CL bare bulb strobes use H mode which is the rapid pulsing to create a long flat power curve for the duration of the shutter slit travel. Two completely different approaches. Similar result.

H mode and Hyper Sync both are relying on the shutter speed to stop action since they are both constant light sources for the duration of the shutter travel and would do a poor job of stopping action.
