So your FT03 with a De-domed SST-40 = 1780lm @ 305kcd
After SBT90.2 swap……………………… = 4990lm @ 355kcd
Although the swap increased intensity by 50 kcd, most of the addition lumens went into the spill beam and not downrange. Is that about right? As you mentioned, the reflector doesn’t seem optimized for the 90.2. I think we should hold off buying this light until someone can test a sample and confirm that adequate changes were actually made to make use of the 90.2. Seems a disappointment right now. Glad you tested it!
@KawiBoy1428 Did you have any throw numbers before the dedome? You’re numbers seem a bit low. Could just be the meter you’re using. Two other users measured 357/367 kcd after dedoming.
Lumen increase in the beam should be almost proportional to that of the spill. So with small improvement in cd and big lm - the beam ought to be much fatter.
Yea well this is a direct comparison, stock lights with emitter changes, stock centering rings, no shimming for focus, both done at 5meters. I’m sure I could tweak both lights to get more, but it’s not worth my time with little lights…not like my GT and GT70 with real (not shaved) de-domed E4 XHP-35 and de-dome XHP-70.2….where I spent countless hours on…
You could add 50kcd to the 90.2 355kcd and it’s still not that impressive….over other peoples de-domed SST40’s…
Performance is around the same as a TN40 v2. I guess they could get a bit more out of it if they tried but it still seems pretty good for it’s size and price. I guess we’ll just have to wait and see. Maybe the actual production version will perform better.
Overall beam thinness makes K1 a very specialized tool. FT03 with SBT90.2 will be much more universal despite not throwing as far.
That said I expect that Hank will offer SBT90.2 eventually, though he hasn’t commented on the topic yet.
By the way is this not a good meter?
SBT90.2 white and red.
