The Linkstar Studio Flash Set LFK-250D is a complete flash set for professional users. The two included Linkstar LF-250D studio flashes, each with 250 Ws of flash power, offer everything you would expect from a professional studio flash: a fast recharge time, a robust metal housing, a professional S-bayonet mount for accessories, fan cooling for extended use, and a built-in slave receiver (which can be turned off). The flashes can be adjusted very precisely using digital displays. The included 150 W modeling lamps can be turned on and off, and their power can be set proportionally to the flash power. The flashes also feature an auto-dump function, meaning the flash automatically discharges when the power is reduced. A ready indication is provided via an LED and a switchable beeper.

The lamps are equipped with a standard spigot mount at the bottom, allowing them to be attached to almost any tripod. The lamps have a Linkstar bayonet mount at the front, enabling various accessories such as softboxes and reflectors to be connected. The S-bayonet mount is also compatible with some other brands that use the S-bayonet mount, such as Bowens. The base also includes a umbrella holder for the included reflective umbrella.
