|What, only 122 grams with batteries? UTMB here I come!|
We also have to keep in mind that the rules of races like UTMB require competitors to carry an extra set of batteries or risk getting disqualified. A set of 3xAAA batteries weighs about 40g less than 3xAA. So the total weight saving with extra batteries is about 100g. That may not seem like a big deal, but with all the other gear it all adds up quickly. In a 168km mountain run (the distance of four marathons), every gram counts.

How about the performance of TR2? I have test-driven TR2 through Finnish winter in freezing cold, below -18˚C (0˚F). Our days here can be darker than nights in the south. So far I'm impressed. By combining a strong spotlight and a wide floodlight Silva lights up the trail ahead pretty well. The light distance is about 45m/20 meters in max/min mode. The beam is actually not that wide, but neither is the trail usually, so it's ok I guess.

Of course the trade-off between the light output and battery life is something to be considered. Many LED-lamps boast a lot more lumens, but what's the use of all that extra illumination in ultra trail running if the batteries will last only a couple of hours? Silva claims TR2 burn time is 30h/48h in max/min mode. I have not been able to verify this myself yet, but I believe that to be about correct in ideal conditions. That might mean that I might not have to change batteries or torches during UTMB (two nights). However in extremely cold temperatures the burn time will understandably and inevitably be somewhat less than ideal.

I love the simple design of TR2. There is only one button to press and it is large enough. The first pressing turns max mode on. The second press switches to min mode. When on, a long (>1s) press turns the main lights off, but turns on a green/orange/red battery indicator light for a few seconds. When off, a long press turns the flash mode on. That's all: no computer software (which in Petzl case was a buggy piece of crap anyway).
Okay let's wrap it up. Buy this good lamp (the price is reasonable, I paid 73€ for mine) and see for yourself. See you in Chamonix in August - I'll be the happy dude wearing a Silva Trail Runner 2!
