I nearly pulled the trigger on the TN31 until I discovered that the temperature control on this flashlight can take the lumens down to 809 or so from 1147.
So is this really an 800 lumen light but when the conditions are right it can run at 1147 lumens.
What is the general opinion about this, and has anyone else seen this documented or experienced this kickdown themselves?
I really wanted to buy this light until I read an article on the temp control.
Am I allowed to post the link to the light review site where the review came from?
Doing so on CPF would have me in the Electric Chair!!!
I would like to learn from others experiences and other review sites before I laid out $200 or more on a light that has traits or features that I never knew about.

The problem with DX and Dino is slow shipping and unreliable customer service. An example of this is one time a member here received a lip phone instead of a flashlight. I have had a DX order take 5 months.
I usually use Amazon.com or Ebay or Light Junction or one of the bigger vendors.
Amazon just sent me a new order after the shipping company lost my parcel in transit for free as a replacement and then my original order turned up at my house a few days later, so I had two of what I originally ordered. Good customer service!! And Amazon said I could keep both!!
Thermal dimming is nothing new, high current LED lights have been doing this since day-1. How much each light dims varies widely, and there really is no set rule. Its also not uncommon for manufacturers to advertise their brightest lumen output... IE best case scenario.
FWIW I won't be adding this light to my collection either... its just too big for all practical purposes, and IMHO it costs too much for what it does.
A drop from 1147 to 690 is pretty huge though. Factoring in reflector and lens losses, that XML needs to be pushing ~1300 bulb lumens upon initial turn on. Theyre definitely driving it!
So I guess this answers the question for me (which I asked a few weeks ago and got no answer to)--as to why the 800 lumen M31 Triton with SST-50 is supposed to have a 700 meter throwing distance while the TN31 has the same figure with 1100+ lumens. Doesn't make sense--unless output drops drastically as the article states.
I have said before that I think integrity and reliably with estimations on performance stats have a long way to go for so many companies (with budget and name-brand lights and among their fans).
There's either something wrong with his light or his testing because two comments down from that he said the max he ever got from it is 809 lumens. I have one of these and mine is at least 1100 lumens. And it kicks the crap out of everything else I have -- no contest.
So if it gets 73400Lux from 809 Lumens, then by the time it drops to 695 Lumens the corresponding Lux will have dropped to 63,056Lux (Assuming its a linear correlation).
Thats not that much brighter than an STL-V2, Fandy-V6 or modded HD2010... which all can push the 45-50K range, at a fraction of the price and ~half the size size.
It's definitely not 809 lumens. His light is defective or his testing is wrong. Trust me, I own one of these. BTW it puts out 3X the lux of an HD2010 which I also have and have tested it against.
The reviewer claims he never got more than 809 lumens to begin with.
