Also have a look at the Travor MTL-900-II. This gets sold under a number of names from Neewwer to Polaroid for more money, but this shop in Swnasea where I got mine a couple of years ago sells them under the Travor brand for £66. It's 1 to 2 stops brighter than an Icelight, and has a removable Sony N series battery (Icelight's battery is non-removable), and a standard "1/4 20" thread in the bottom. It comes with a tungsten correction tube and a remote. It's solidly built out of aluminium. I also have a set of barn doors for mine, but I had to get those from a supplier in China - I've not seem them from anyone local.

TBH - I mostly use it for checking prints as it's daylight balanced
