Yes you can measure it your self.Installed in light,fresh batteries,turn it on,unscrew tail cap,connect DMM pres set to 1-10A range probes in-line between exposed battery end and light housing. Guess you can check of of light but I do not know how long pill can be ran without heatsinking.
Sometimres it is difficult to know how to help someone on a Forum. I recomended a fellow CP member who is a US dealer to answer your question. Seemed logical to me. Sure you can contact the manufacture direct but perhaps their english is not so great <Edit >I see you are in Denmark>.,perhaps they will takes days or weeks to answer. If you were really into any kind of electronics then I would assume you allready had a DMM and knew how to use it. Often if an answer such as use a DMM / DVM / DC Amp. meter is given the next quest is what is that then how do you use it?

Hi UlrikJ, the 1.2 amp 3SD pills will typically measure 1.35 to 1.40 amps (current draw at the tail) on the high mode, using a fully-charged 18650. 
Hi Turbo Guy and FlashCrazy
I have just done the measurement with my DMM (approx. $100 worth (I know is not the best nor the worst)) and the result was 1.6A at the tail cap in high mode.
What do you make of that result, FlashCrazy ?

Definitely sounds like the 1.2 amp version, and either a battery that wasn't fully charged.. or perhaps a little worn out. The 3SD is regulated, so as the battery's voltage goes down, the amp draw from the battery will go up. If the battery is older (or has had a hard life), it's voltage will sag in use more than when new, and will result in a higher current draw.
