The following reviews are quoted from the biggest super store in the world, B&H New York: stippy from paramaribo ,, this is the best lamp i have ever used,it perfom good from a great distance the size is the only thin that impedes me " ; from chuck8403 from Lousville ,, Great for interviews and single item shots. Lightweight and portable. Has many options to filter light " ; John Mateos from Phillipines ,, Fantastic Equipment... worth the money! " ; Maury from California ,, Its one of the better LED lights, a little heavy on the camera. It needs a 3200 filter screen. I also purchased the Varizoom light and found it to be better all around and even cheaper. " ; Joule Endworld from Argentina ,, This product is ideal to use it in weddings, birthday, etc. Very compact and very wide his(her,your) ilumnacion. debera to feed on compatible batteries, since it does not work with the battery impact np-f970 " ; Chelita from Florida ,, This is my first on-camera light I have purchased. I used it for a wedding and it worked well. I love the dimmer and the controls on the light direction. I shot for about one hour with the light and the battery is still full. It also fits on the shoe of my smaller camcorder." ; JR from Forth Worth Texax ,, I use this light system for filming weddings and it gives me a very good light source for that kind of job. I really like the true color it give me. The dimmer is great and the filter it has are very good help. If I would say something bad about it, it would be the size of it, is a little big but a very good light. It to bad it does not have filters to change the color temp. of the light but home made ones works well. It really does last about 5 hour with full dimmer on. finally I dont recommend anyone useing anything smaller than a Sony HVR-V1U to get this light because of the its sizes. I use a HVR-Z1U. " .
