I am a user of the brand, I have two COLBOR CL100X lights. The portability is the best thing about the lights, but when it comes to illuminate small spaces, the light spreads too much, which doesn't give much creative freedom.
The problem with the one I have designed is the size, but I had no other reference to make the design (I preferred it to be a little more in line with the mood of the light).
Adding to the effect that a fresnel provides, the lights would have a little more power that added to its portability, would be a very useful accessory.
