Westcott FJ400 400Ws Strobe

For the longest time cheaper units produced in mass in China had flooded the market driving out major players from acquiring a foothold in the more affordable lighting market segment. These Chinese companies had gone from producing products for their Western customers to becoming global players in a market that had a ubiquitous number of rebranded lighting products.

Westcott known for their high-quality softboxes and continuous lighting products in one big sweep announced not only their incredibly affordable Westcott FJ400, 400Ws strobe but also a flash trigger that can work with a variety of cameras, a first of its kind a market that thrived on selling brand exclusive triggers and flashes.
