Any idea how this flashlight Ultrafire U-F19 perform? Some interesting figures: Hi > Lo > Strobe > Infinite Brightness Adjustment 85mm head diameter (vs TM36-90 mm / K60-88mm) 210mm length (vs TM36 Lite-195mm / K60-206mm) 640g 2789lm (only?) 5.“TM36 with XHP70”Screw threads seems not very reliable 3x 18650, why not 4x?

Didn’t seem to be much interest. Wonder how much different the unbranded version is?
