Santa came early! Today I got my SST-50 drop-in from Kaidomain. When I opened the package I hesitated because I thought they sent me two by accident! I forgot that the order included two reflectors..

Anyway, I'll cut to the chase. This thing is impressive..:eekster: ! To those who thought that the output would be somewhere near 400 lumen, let me just say....
NO FREAKING WAY!
First thing I did was take it outside and shine it around off my balcony. It is
BRIGHT! VERY BRIGHT! I compared it to my MTE P-7 torch and my Aurora MCE torch. Unfortunately the ground is very wet right now where I live so it's really hard to tell how far it is actually throwing. I'll know more about that in a couple days if we don't get any more rain. ( fingers tightly crossed..

)
Just keep in mind this is a
preliminary review, my first impressions. First thing I noticed: It looks to be brighter than my MTE P-7 torch. The fact that I can notice that under the current conditions is significant in my book.
That means in has to be somewhere over 600lm with a fresh battery. The beam pattern looks to be very similar to my P-7 torch with a nice combo of flood and throw and here's the kicker... The spill looks brighter and whiter than my P-7! Also, the beam itself ( regardless of what reflector used ) looks flawless. No artifacts, rings or halo's, just pure white light. The beam tint looks very Cree'ish, a nice neutral white, no tinge of blue or green or yellow. None of the reflectors given look to provide an overtly narrow beam pattern unfortunately. Perhaps the smooth one has more throw but I really can't tell for sure at the moment. I'll know more about that come the weekend.
I also did a wall test and it looks brighter than the P-7 torch at first glance. However the beam tints are so different it is hard to judge. It compares favorably with my Aurora and looks brighter because it has a wider beam but the Aurora has a more intense hot spot which is why it has been my favorite helmet torch. More comparisons will be done in the next couple days for sure. :thumbsup:
Lastly, this drop-in functions like a true bike light. It has three usable light levels. Medium looks to be near 225-250lm, low under 100lm but good enough for slow fire road climbs. Oh and this one has memory which looks to work for once and there are no stupid flash modes.
Just how well this is going to work as a bike light remains to be seen. I have no idea what the run time is going to be like but output could drop significantly when the current drops below 1.75A. Kaidomain listed the output for this drop-in at 550lm. If that's true it's the brightest damn 550lm I've ever seen. :rockon: Can't wait to compare this to my Dinotte 600L. I'll get back when I have some more low-down. :thumbsup:
