If you want this to fit on the panel thats mounted on a stud you'll want to drill a hole as pictured to work. The dimensions work for the smaller budget panels found here

utilizzato su dei led Weelite, si monta pefettamente in 5 minuti. Semplicemente perfetto, ovviamente avendo il led gia un pannello opaco va aumentata molto la luminosita se si installa anche il telo bianco, ma il risultato e' ottimo.SUPER CONSIGLIATOsiccome sono rimasto super soddisfatto ne ho acquistao un secondo....

After buying a different softbox for an LED panel (which didn’t fit right and was “okay” at best) I didn’t have high expectations. But when I opened this and assembled it my mind was BLOWN at the quality for the cheap price. It is very solid, perfectly sized for my LED panel and diffuses & shapes light well. No complaints

This does the job for the Elgato Key Light.

Most honeycomb soft light filters on the market are square shaped, so finding one that fits Elgato’s Key Light was difficult.This product is of good quality, attaches easily with velcro straps on the back and, minus an inch on both sides, fits Elgato’s Key Light reasonably well.Just keep in mind that with your light source softened and light spill reduced, you will have to rebalance the composure of the scene by increasing your LED panel brightness or raising your camera’s ISO. (Or in my case, both)Overall I’m quite happy with the result. 👍

Does what it says on the tin. I’m impressed with the quality.
