I am not usually a fan of 2x series flashlights (bc of their length) but this looks awesome! Reminds me of the Old Lumens Contest (last year?) Convoy L6 converted to a MT18s...
I really like 2x series flashlights. They are very practical. This flashlight looks very interesting. However, as much as I like Nightwatch for their excellent heat sinking and pushing the envelope in raw performance, their driver efficiency sucks. Their flashlights are meant as toys because of the low driver efficiency. I wish they start making regulated buck / boost drivers.
ive never owned a night watch, good to know about the heat sinking and poor driver efficiency. Maybe bc this one is 2x series it will be a different type of driver (buck?), or maybe it will be easy to find a replacement driver bc it's running off of a tailswitch, maybe mechanical?
I really want to give this light a try but the numbers are not coming out right. Nightwatch has a single 21700 triple SFQ55, Nightwatch NSX3. It’s stats are for three 5000k SFQ55’s are 9100 lumens at 33 amps. This LED comes in 3 and 6 volts varieties. To run 9 SFQ55 LED’s in the 6 volt style will take 50 amps to get around 28,000 lumens.
This chart suggest we might be at 60 amps with 2-21700 in series to get that output.
