Westcott FJ100 100Ws 4-Light Backpack Kit with Sony Trigger

Four-light portable kit

The Westcott FJ100 4-Light Backpack Kit supplies four ultra-compact 100Ws strobes, a Sony-compatible FJ-T1 S wireless trigger and a carry backpack. It is built for photographers who need professional off-camera lighting that travels anywhere. Each strobe is about the size of a soda can and combines battery power with touchscreen controls. The kit suits location and studio shooters who want a complete wireless system in one bag.

0.01-1.6s recycle range

The single specification that decides fit is the recycle time of 0.01-1.6s, which determines how quickly the strobes can fire at full power between frames. Colour temperature is held at 6000K +/-200K for consistent output across all four heads. Each 3200mAh battery delivers 700+ full-power flashes per charge and can be recharged or run via USB-C without stopping the shoot. Buyers who need faster recycle or higher watt-second output should look elsewhere.

Touchscreen and wireless setup

Installation centres on pairing the FJ-T1 S trigger with the four strobes over the FJ Wireless system and using the bright LCD touchscreen to adjust power, groups and settings from the camera. The trigger is dedicated to Sony bodies, so it will not control the lights on other brands. A common issue is forgetting to match group channels on every strobe before shooting, which leaves some heads unresponsive. Battery contacts should be kept clean to maintain the 700-flash rating.
