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.
