My specialty is working with radio-controlled external Speedlites. I basically do not work in the studio but always on location must be a maximum of my equipment mobile. Frequently, there were situations where continuous light makes work much more relaxed because you do not have to only shoot a photo and check on how the shadows are actually like. The Icelights I let my assistants the lamps move centimeter way to the light and shade to sit as long as exactly as I want them.
The dimming of the lamps is also optimal and so not the case with cheap Baulampen.
Flickering lights from a hardware store and are not to be used for video.
Also for infant and young child photograph where you can not use a flash, these lamps are ideal.
The processing is reminiscent of a baseball bat, very robust. There are stable thread in both ends.
No matching adapters are enclosed with regards Switzerland, I also had to help me with another cable.
The battery lasts depending on light intensity one hour, the lamps should be switched on only possible when one is shooting well.
For me, something I've been looking for. Possession now two piece along with the gel and flights run sets optional.
