Compare Westcott studio and video lights by flash power and kit format. Find the in-stock strobe that fits a portrait or studio setup.
One- and two-light touchscreen backpack kits
Start by separating flash from continuous light. These Westcott options are strobes for still photography. Their watt-second ratings describe flash energy, not continuous output for video.
The Westcott FJ400 II Strobe 1-Light Backpack Kit with FJ-X3 S Wireless Trigger costs $999.90. The Westcott FJ400 II Strobe 2-Light Backpack Kit with FJ-X3 S Wireless Trigger costs $1,599.90. Choose between them by the number of independently positioned lights the job requires, rather than expecting different performance from each head.
Both use the 400Ws FJ400 II. Westcott rates recycling at 0.01 to 0.9 second and battery endurance at 550+ full-power flashes with the FJ Pro Battery. The strobes have a 9-stop power range and full-color OLED touchscreens with built-in help screens. A Bowens S-Type mount provides the modifier connection.
The one-light kit suits portraits built around a single main source. Two lights allow separate key and fill placement, or a main light plus a dedicated background light. That second source adds control over the lighting arrangement; it does not increase either head's individual 400Ws rating.
Each FJ400 II also has a 30W bi-color LED modeling light. It helps preview where illumination and shadows fall before firing the flash. Battery and AC/DC power flexibility makes these kits relevant to location work as well as a fixed studio.
A two-light portrait kit with a different trigger
The Westcott FJ400 II Wireless 2-Light Portable Portrait Flash Kit with FJ-X3 M is $1,049.90. It is an FJ400 II two-light package for portrait photographers shopping specifically for two sources.
The core strobe specifications match the backpack versions: 400Ws, a 0.01 to 0.9 second recycle range, and 550+ full-power flashes with the FJ Pro Battery. It also has the 30W bi-color modeling light and Bowens S-Type mount. Westcott specifies flash color temperature at 5500K ±150K in Normal/TTL operation.
The purchase distinction is the package and trigger version. This portrait kit names the FJ-X3 M; both FJ400 II backpack kits name the FJ-X3 S. Match the trigger to the camera before deciding on price. For someone prioritizing a two-light portrait arrangement, this package offers the same stated FJ400 II flash performance as the $1,599.90 two-light backpack kit.
800Ws from one head, with a battery tradeoff
The Westcott FJ800 Touchscreen Strobe with FJ Pro AC/DC Battery costs $999.90. Its 800Ws rating is twice the flash-energy rating of a 400Ws head. Buy it when more energy from one lighting position matters more than having two independently placed sources.
Extra flash energy is useful when stopping down the lens or compensating for light lost through a modifier. It does not replace the placement options of a two-light kit. A single stronger main light and separate main-and-background lights solve different problems.
Westcott rates the FJ800 at 0.01 to 1.8 seconds for recycling and 250+ full-power flashes with the FJ Pro Battery. Against the FJ400 II, that means a longer maximum recycle time and fewer rated full-power flashes per battery. Those are relevant tradeoffs for a session built around repeated high-power exposures.
The FJ800 weighs 7.5 pounds with its battery. It has a Bowens S-Type mount and a 30W bi-color modeling light, plus LED group color indicators to help distinguish group assignments. Its full-color OLED touchscreen provides settings control and built-in help screens.
A $699.90 two-light kit with a Sony trigger
The Westcott FJ400-SE 2-Light Studio Strobe Kit with FJ-X3 S Trigger for Sony costs $699.90. It contains two 400Ws battery-powered heads. For a photographer using a compatible Sony camera, it provides separate main and secondary lighting in one package.
The included FJ-X3 S provides wireless power control and high-speed sync support. The strobes offer a 9-stop adjustment range, 5500K color temperature and Bowens S-mount modifier compatibility. Power can come from AC or a rechargeable lithium-ion battery; the listed AC operating voltage is 100–240V.
Choose this kit when two lighting positions are the priority. One head can light the subject while the other handles the background, rather than asking a single source to do both jobs. The FJ400 II alternatives put their OLED touchscreen interface and specified recycling performance into the buying decision. The FJ400-SE package puts two 400Ws heads and a Sony trigger at $699.90.
A $690 single-light backpack kit for Sony
The Westcott FJ400 Strobe 1-Light Backpack Kit with FJ-X3S Wireless Trigger Sony costs $690. It suits a photographer who needs one 400Ws source and a trigger for a compatible Sony camera, rather than a second head.
Westcott rates this FJ400 at 480+ full-power flashes per charge and 0.05 to 0.9 second recycling. Compared with the FJ400 II, it has a lower rated full-power flash count and a different lower end of the recycle range. The maximum listed recycle time remains 0.9 second.
The removable AC/DC battery is lithium polymer. Power adjustment spans 9 stops in 0.1- or 1.0-stop increments, useful for making small exposure corrections without moving the light. Westcott specifies 5500K ±150K color stability across the energy range.
This kit supports TTL and high-speed sync up to 1/8000 second. Its 2.4 GHz trigger works with many Sony cameras, not automatically every Sony body. The wireless specifications include 16 groups and 32 channels. Continuous Capture is rated up to 20 frames per second, dependent on the camera model.
How to choose
- Single-light setup for $690: Choose the FJ400 backpack kit if its Sony trigger compatibility matches the camera.
- Two-light setup for $699.90: Start with the FJ400-SE kit for compatible Sony cameras.
- FJ400 II performance with one light: Choose the $999.90 one-light backpack kit.
- Two FJ400 II lights: Compare the $1,049.90 portrait kit with FJ-X3 M against the $1,599.90 backpack kit with FJ-X3 S. Resolve trigger compatibility before price.
- More energy from a single head: Choose the $999.90 FJ800, accepting its longer maximum recycle time and lower full-power battery count.
For video-first work, shop for continuous illumination rather than selecting by a strobe's watt-second rating. The FJ400 II and FJ800 have 30W bi-color modeling lights for previewing illumination; their 400Ws and 800Ws flash ratings do not describe those LEDs' output.
