I decide to get "real" and pulled the trigger on the purchase on the new TK41 from Fenix which uses new XM-L emitter. (same as new MS 900?)
I don't know how to benchmark it -but I can tell you right now - and this is not just BS - the TK41 is a hell of a lot brighter than the new MS 900.
When I tried to compare beam spots - TK41's hot spot made the wall look like it was being burned with a magnifying glass. I had to turn the TK to the 335 lumen setting to approximate beam intensity.
In my opinion -using the Fenix TK41 manufacture specs as a lumen benchmark,
I would describe the new MS 900 to be running at 500 lumen. It is no brighter than a TK41 set to 335 lumen. But the MS900 does have a more diffuse flood, and a resulting dimmer shorter throw/diffuse spot area.
Hey Colleen, how bright is the MS dive light? Same deal?
I wonder what is the bin of the Fenix TK41, they might be using a U2 bin instead of the T6? The T6 bin xml which the MS use does have a Tint that I can only describe as weird. It look white on a white wall but when I use it out on the road, it has some yellowish almost a Neutral trint. That alone will make it look less brighter. Not just that but the outer ring and the hotspot have different tint to it.
I did have a chance to do some ceiling bounce test to see if the new MS xml is indeed brighter than some other lights I have. I have a FC light meter which I converted the reading to LUX with the 10.76 conversion. I found a setting in the house where I took an old MS900 P7 and got 37 Lux out of it as control settiing to do the other light test. All number are from a white ceiling bounce test. Here are some number that maybe interest:
MS 900 P7----------------37 Lux
Gemini Titan--------------42 Lux
Shiningbeam S mini-------28 Lux
MG XPG R5 Rocket--------33 Lux
MG X thrower SST50------43 Lux
Bikeray IV on Hi-----------82 Lux
Bikeray IV on low---------16 Lux
MS XML T6--------------63 Lux
Base on these number, I can say that the new MS XML is brighter than most light that are in the 500 Lumen range. My best guess is that it probably have an OTF of about 700-800 lumens.
