OK so this light has it's plus and minus. The light output is not too bad and the battery life was over 7 hours on a test run. However, this thing comes with a "frost screen", which is actually a thin bit of plastic clipped over the lens. This is supposed to make the beam wider, 40 degrees, which it does well, when you remove this lens, it is supposed to become a 20 degree beam, according to the ADJ website. However this is where the problem is!
With the filter removed, the light is terrible! The "spot" is a twin ring of broken light, with really very bad colour mixing, you can see splashes of all the mixed colours and the beam could not be considered a pin spot at all! I guess ADJ included this special "filter screen" to cover up the mess they made of the original lens and colour mixing! Again with the filter, it's nice and even, but of course a very wide flood, but without the frost filter it's practically useless!
I only got one to try and result is, I can probably find some use for it, especially as it runs on batteries, but I will not be buying any further units!
