Q: 1. Flashtube

A: The Westcott FJ200 Strobe BH #WE4740 uses the BH #WE4745 flashtube.

Q: 2. Somebody asked if this uses a Bowens mount and someone replied yes. But I watched an FStoppers video for this light and Lee said it uses a smaller proprietary mount. This looks very similar to the new Godox AD300 Pro which uses a proprietary Godox mount. So which mount is this light actually using? Could it be the same as the AD300 Pro?

A: Yes you are right it is not a Bowens mount, they have not announced yet the size of the mount.

Q: 3. Why does the link to B&H for a Bowens Mount result in showing a Godox S2 Speedlite Bracket for Bowens? Does that mean that the S-2 type Bowens mount would work with this strobe? And the 'Part # link' shows no such item. Is there a Bowens mount for this strobe. Asking 10/3/21.

A: Yes, the Godox s2 bracket allows you to mount the system to the FJ200 and adapt to the Bowens mount echo-system. Godox S2 Speedlite Bracket for Bowens https://bhpho.to/3AdZ0xb

Q: 4. What are the flash durations at each power level?

A: Westcott does not list the flash duration of the Westcott FJ200 Strobe at all power settings. They only list the maximum and minimum flash duration, showing the t0.1 flash duration measurement (when the light is emitting 90% of total light) in normal mode is 1/260 second at full power and 1/2600 second at minimum power, and in freeze mode, the flash duration at minimum output is 1/7000 second. At the t0.5 measurement (when the light is emitting 50% of total light), at normal mode, the flash duration would be 1/800 second at full power and 1/8000 second at minimum output power, while at freeze mode, the duration at minimum output would be 1/20,000 second. For flash duration measurement at other output settings, you would have to contact Westcott directly by e-mailing them at sales@fjwestcott.com or by calling them toll-free at 1-800-886-1689 Monday - Friday, 9am - 5pm ET.

Q: 7. Does it come with bowens mount?

Q: 8. Is this compatible with Leica SL2?

A: Yes, you may use the Westcott FJ-X2m Universal Flash Trigger for FJ400 Strobe, B&H # WEFJX2MUWLFT, included in the above Westcott FJ200 Strobe 3-Light Backpack Kit with FJ-X2m Wireless Trigger for your usage needs. When the FJ-X2m trigger is placed on the hot shoe of the Leica SL2 Mirrorless Camera, it may wirelessly trigger the FJ200 strobes in this flash kit. Do note you will have to set your flash output manually as you will not have TTL automatic flash exposure capability with the Westcott strobes (as of the date/time of this reply).

Q: 9. Can this be used with AC Current?

A: Yes the FJ200 flashes can be used with AC but you need for each flash the AC power adapter, Westcott FJ200 AC Power Adapter BH #WE4749 • MFR #4749 The link is https://bhpho.to/3EfB4Pu .

Q: 10. Can this work as a slave ?

A: If the Westcott FJ200 Strobe is set to Manual mode, you may use the built-in optical sensor to fire the strobe once it detects the light output from another photographic strobe/flash. Likewise, if you connect the Westcott FJ-X2m Universal Flash Trigger to your camera's hot shoe, you may wirelessly trigger the Westcott FJ200 using the wireless radio remote as the FJ200 has a built-in integrated FJ Wireless Flash System radio receiver.
