A few DBS V3 questions

I've been trying to choose a thrower for a while now and like the look of this guy but have a few questions.



Firstly this is the list provided by the site i intend to buy from..



1SM XP-G R5 = Single output level. 1x 18650 battery, 2 x CR123 or 2 x RCR123.

3SM XP-G R5 = Three output levels. 2 x CR123 or 2 x RCR123.

3SM MC-E = Three output levels. 2 x RCR123 or 2 x 18650 with optional extension tube (+ £5 for MC-E model)

3SM SST50 = Three output levels. 2 x CR123 or 2 x RCR123. (+ £25 for SST-50 model)

1SM SST50 = Single output level. 2 x CR123A, 2 x RCR123A or 2 x 18650 with optional extension tube (+ £25 for SST-50 model)



I've removed some options as i'll only be using RCR123's, could someone please let me know which of these options would produce the most throw?



Also i was keen on the Thrunight catapult but then saw a pic of it in someone hand, its way too big for me, would anyone happen to has some pictures of themselfs holding a DBS V3?



Lastly this has to be the only light i've ever seen that does not list its output / lumens / lux.. nothing. Does anyone know what its capable of and is the top output possible with 2 RCR123 without any kind of extention tube?



Thanks in advance
