My TR-1200 is an Awsome thrower to me with loads of good usable spill and longs run times on 3 x 18650's. I've had mine almost a year and have done a lot of bush walking with it gunned on high for 60 + mins. Mine used to out throw a usa168 the same thing as a hs-801 driven at one amp and I did use r2 and q5's in the usa168.
The tr-1200 will dim to warn you low battery voltage. I got mine from DX, there is some floating around that have a plastic lens and only 2 x 18650 but the one I got from DX was the 3 x 18650 and glass lens ofcorse. I've found it to be great and relible.
I found it great for camping, fishing, showing off and bush walks due to it would light kangaroos up in the distant fields or threw the trees while giving realy good spill so you could see every where around you while your walking, plus the added run time of 3 18650's.
Plus the fact you can buy cheap empty tr-1200 hosts if you ever scratch it up or damage it or need host parts for this reason I would recommend the tr-1200. Plus the UCL lense fits it. The tint on mine is nice no blue, green or purple tint a bit warmer then a t6 Xm-l
And just incase you did not know an xr-e q5 led is more of a thrower then a Xm-l led due to the narrow beam of light it puts out, the Xm-l puts out a wider beam with less throw, so needs bigger reflectors plus the Xm-l t6's have more of a blue tint that makes them look more punchy, but because the tr-1200 has 5 times xr- q5's in narrow short reflectors it puts out realy good spill but maintains the throw really well.
He is an old thread on the tr-1200
A quick recap it's cheap to buy, you can buy the empty host cheap for spare bezels, heads, glass lens, battery tubes, tail caps with switch and you can buy switchs separately cheap too. On 3 x T18650, it will give you Over twice the run time over the stl-v6, but it's not really a pritty light but to me is more practical, for price, spare parts and run time.
One day I will buy the HA111 tr-1200 ad my UCL lens and keep my old tr-1200 for spare host parts for my tr-3t6 and keep the screw in as a spare or mod it.
