Ooops, didn't know about this thread. I've got a sample EDC05C and will be posting a review, but with limited knowledge about it. Neal sent me one. Funny, at first I was thinking it was an XPL HI but could be a XHP35 HI - definitely a HI though - I'll try to better confirm it's XHP35 HI. The side 219C's are so heavily diffused, you don't have to worry about any tint issues around a hot spot or corona. To me it looks just fine - neutral enough, lots of wide coverage - lights up a small room. I can answer questions about it, least of what I know - doesn't look easy to do a tear down though, haven't tried a couple techniques yet on the bezel. It's body is one piece, slightly raised blue bezel, probably SS, and threaded in end cap made of SS. Nice thread cuts on the tail cap, easy to tighten up to catch threads my one finger.
It doesn't do blaz'n XHP35 HI #'s in either lumens or throw, unless there's a hidden turbo I don't know about. Still it can eat 14500's. I got no manual or specs - learned a couple things from what's in the OP actually...
Edit/Update: definitely an XHP35 HI in my sample (using CRX's great info: https://budgetlightforum.com/t/-/23020)
Martin - please update the OP, assuming my sample is correct 
Ohh, I see the BG listing now, boy that must be new... It has the best info on this light. The UI described matches my sample exactly.
Anyone know what a Nichia NCSLE17 is? Found this: https://www.futureelectronics.com/p/7070807?utm_source=octopart.com&utm_medium=cpcbuynow&utm_content=instock&utm_campaign=Octopart_Ext_Referals
