I felt exactly the same about the Nightwatch NS73V1, the triple SFN55.2 light, and as a long time loyal Nealsgadgets.com customer was hugely disappointed to be thwarted by the stinging **SOLD OUT** message for the NS59V1 moments ago on Neal's site exactly when I wanted to pull the trigger (arrrrrgh!) and BUY NOW.
Same thing happened with the NS73V1. SOLD OUT many weeks (months?) ago when I rushed to get one, hoping stock might replenish, to no avail.... kept checking each week, email inquiry, to no avail. I still really want one... quite saddened he never obtained more. I fear this might be the case with this new light .... unobtanium.
Please Neal, I'd buy them both in a heartbeat if you could obtain more.
Interested, even if its 18-20k lumens it would still be a good buy. It could maybe make more considering it should be much more efficient than the Nightwatch NSX3 using 6v LEDs plus more LEDs should make it more efficient. 3amp at 6v yields 2200 lumens from this LED?
