90 mm is in line with their biggest lights, I wonder if that’s intentional to use the same head design or meet some manufacturing or shipping maximum. Maybe that’s the largest bar stock they have on order lol.
My guess is that their primary audience is more main stream than flashaholics looking for ultimate throw. For the same reason Nitecore lights like a lot of their Tiny Monster models are cool white only.
:person_facepalming: Been messing with it since Sept/Oct 2019 when the SBT90.2 was the rage, tried boosting the stock driver so I could keep all the electronics… just a PITA pulling everything out and putting it back together, like 5 levels of electronics and switches have to be routed correctly to fit all that shit’in a tight space and not cut/destroy/fry anything, what a nite mare of an assembly process… :rage:
Then the mechanics…. machining the copper heat sink, fitting the mcpcb, tabbing the contacts, positioning the Copper threaded Heat sink LED/mcpcb, focusing, machining the reflector, (because it was threaded into the head) to help facilitate focusing… :person_facepalming:
But it’s done, works very, well pretty happy with it and the reflector is still pristine….
I’m glad they have one option with sealed cells and one with a pack to serve everyone’s needs. I’m also happy to see they seem to have used the UI from the EC4GTS that I loved.
^ Definitely a lot more expensive than similar lights with something like an XHP50.2 emitter. There is going to be a decent discount with a code, but I recall the light still being fairly expensive at around US $90 (with code).
So definitely not cheap, but I believe it’s a killer emitter.
So also in the Nitecore TM38 the Luminus SBT-90.2 LED has been implemented. Was it worth it? Since the price has now quite increased, what advantages are there in the TM39? Well, now the beam distance goes from 1400m to 1500m! As much as 100m more!!!
Unfortunately, in order to achieve this extraordinary improvement, the output had to be almost tripled (1800 —> 5200) so now the runtime is quite shorter and the light gets hotter. In addition, you can no longer run the turbo indefinitely. These are not upgrades!
But what is the criterion adopted by Nitecore for this new version? $500 for a 1500m thrower when there are on the market some lights that cost half as much and have an almost double-throw (Acebeam K75, Lumintop BLF GT90). Moreover, an increase of 100 meters is not even noticeable.
Warning: the specifications read that the Turbo and High values have been measured by deactivating the thermal control, so we do not know how long they actually last.
