I’m in the market for a similar light (when I got the money to spend on it). I’ve looked at the Sky Ray Kung, but that is not going to cut it for me because I read in reviews that it heats up to an uncomfortable level after long use. These also seem to be a bit of a crapshoot when it comes to quality and output.
That is why I am going to order a SolarStorm SP03 . This one got slightly less flood than a SRK, but more throw.
You might also want to look at the Supfire M6 groupbuy . This light is reviewed as “how the SRK should be”. And this GB one should be a better version of the Supfire M6, with XML2’s and a better UI.
