The Eagle Eye X1R has had some great deals going, comes with both tube sizes, and is a nice lightweight angle light, and very decent quality. I recently completed a full mod on one, 20 mm MtnE MCPCB, 351D 4000K 90+ CRI, 22 mm DEL driver sanded down to ~21 mm to fit, Infineon FET. For this mod, the tricky stuff is:
Here's some pics of the mod.
Stock setup:
Stock switch board:
Smarts on the back side of the switch PCB:
Stock LED setup:
Removing stock driver:
Here's the rotary tool work. The stock shelf extended to the blue edge, so it had to be cut out maybe ~2 mm so the replacement driver mounts on a thin shelf and can clear the SMD's:
Also the other side was a bit too thick for the driver's SMD's:
After sanding (sanding bit on the rotary tool):
The MtnE 20 mm after filing out spaces for the screws. The screws don't hold down the PCMCB, just keep it from spinning:
351D 4000K, nice reflow (maybe I'm getting better?) with trimming the excess:
New populated switch PCB. All parts removed, replaced LED's with pink ones and using 2 10K's, but probably could have used higher values - it's fairly bright:
The head modded parts at this point, sanded the surface as smooth as I could get but there is the slightly depressed spot for fitting the USB charging circuit there with the blue anodizing shown on the MCPCB mounted surface. I can only assume they were slightly off in clearances:
The new front end stack:
Driver installed with extra length on wires for driver re-programming, using the stock spring with a bypass:
On an Aspire 1100 cell at 4.19V, measured 4.8 amps, 1120 lumens at start (probably a little lower than my normal (non ANSI) numbers.
On a 30Q at 4.19V, measured 6.36 amps. Lumens is difficult to get an accurate # with a right angle light in my PVC light box.
No pics of the beam/tint, but very happy with it - nice milky white, nice soft hot spot with it's OP reflector.
