This build could probably be done better on an aluminum Eagle Eye X6 host. The Khatod 600 series optic is 35mm in diameter with an 11.8mm height so it’s about 3.2mm shorter than the CUTE-3 I’ve used in the past. The key to this optic is the wide opening that allows the XHP-50.2 to be used with the dome on. The extra 3.2mm height required for a copper spacer would be utilized to an extreme with the power this puts out. Richard has the Cutter T-Pad 32mm triple XM-XHP-50 triple MCPCB, as well as the emitters. He can also build the Zener modified FET to drive it on 2 cells.
I opened up the tail cap slightly to allow the back cell to fit further up into the tail cap and alleviate some spring pressure, also allowing the tail cap to thread on all the way. Similar can be done on the Eagle Eye hosts fairly easily. The legs on the Khatod optic have the post too long through the board, I filed those down to fit smooth on the back of the T-Pad board and it works out well. I supposed a standard spacer could be used and two extra 32mm Noctigons (or T-Pad’s) could be added under the main one for that 3mm stack height increase. Should be easy enough really for almost anyone to do it.
It’s an astonishingly bright build, looking forward to seeing some others give it a go and get their impressions…
