The output from the TG06S and the SF14 is pretty close , but I do need to correct myself as I just looked back at my testing charts.

The TG06 makes about 100 70 lumens less than the SF14 and I was thinking they were both 600 lumens.

With Efest 14500 , I tested 531 lumens on the TG06S and 607 lumens on the SF14. Also the SF14 always starts on Low instead of high.

Otherwise as far as size and build quality they are pretty much neck in neck.
