The world of studio lighting is changing rapidly, with more emphasis on simplicity, customisation and portability. This thought process has convinced Interfit to fundamentally change their studio flash range this year with all previous models now discontinued.

In its place comes the F121 Studio Flash range, the best new system we have seen since their introduction of Stellar - over ten years ago. It is light, modern and can be tailor-made to fit your requirements with output and accessories customizable.

* Available in 100W & 200W
* Reliable colour temperature
* Digital touch screen display
* Accurate six stop power adjustment in 1/10th increments
* Fast recycling time
* 75W adjustable modelling lamp
* AC Powered
* Integrated wireless triggering (optional extra)

Being available in 100W and 200W versions mean educational departments, professionals and hobbyists can tailor their studio lighting equipment purchase. Both feature a digital touch screen for accurate power adjustments with stepless dimming and correct colour temperature. The output of the modelling lamp can be adjusted independently or in line with the flash tube power adjustment. It also has a fast recycling time of 1-2s at full power which can be triggered remotely using the (inexpensive) Interfit on camera remote INT910 (Sold separately).

We love the LCD. Its large illuminated figures make it so easy for students to understand the principals of power adjustments.

There are five ways to buy the F121:
