Based on bins: Simon has good 4000K bin on 70cri range and good 5700K bin on 90cri range. I have tested few of those 4000K 70cri ones and they are great.
To get to the other side. 
Thatâs good info. Since XHP70.3 are still fairly expensive and I do not have any other light that could take them, I donât feel like testing all LEDs Simon has and checking which bins are good⌠Experience with them is super helpful.
I donât wanna go too warm on this light, the 5000K I currently have seem pretty perfect for what I use it for, so the 4000K 70 are out for me. I can not see 5700K 90 CRI on Simons shop - only 5000K 90 and 5000K 70 as well as 6500K 70. Guess you were referring to the 5000K 90 emitter?
Supposedly it was added recently but for us Europeans it takes longer for new products to show up for whatever reason.

Oh, the usual Aliexpress fun. 5700K 90 CRI sounds fun for a âbright but good light qualityâ flooder. And user experience regarding a proper tint makes it perfect. Iâll wait 
I think Simon said it takes 1-3 days, a while ago. Maybe sometimes longer.
Anyone thinking that the maker of this flashlight did NOT put in a failsafe to prevent the charging system from working when alkaline cells are inserted?
No I think not, itâs not rechargeable in the light from what I can see. The rechargeable battery pack is charged via the inbuilt usb cable when removed from the light, though you can charge from the light to something else (powerbank funtion)

Thanks for checking on that. Well, they did something smart here. No way someone can do something seriously stupid with the charging.
I know right, never seen an approach like that before - wiring a physical usb cable in the pack⌠neat idea if there is room, shame they didnât use usb c though.
1 Thank
Yeah, first Iâve ever seen of this too. Weird having a built-in cable with USB-A plug that docks flush to the body so the whole power unit can be tucked inside a flashlight. I can see the merit⌠as USB-A is so widespread, and you wonât ever have to worry about not having a cable.
For me thatâd be an immediate no-go, I do not own any USB-A charger outside of the âcrappy old power bricks I may need some dayâ box anymore. Both my home and travel chargers have unb-c only 
I have an old Lupine Piko which manages to get 1200lm at 13W out of 2 XML-U2 (not XML2-U2). While I love the light despite its atrocious UI, it gets hot quickly at not so much light output.
How much output could I get from this light if I emitter swapped it to modern 3V 5050 LEDs? Low CRI, 5700K or something around that ballpark. I need it for running and cycling, as long as the LED ainât green I donât care.
Would I gain a significant amount of brightness, or would the difference be so small that its not worth the hassle?
Is this really necessary? Or just cost cutting is too attractive? Iâve also seen this on my earlier release Wurkkos TS11.
TIR optics are made with injection molding, thatâs where the plastic is injected into the mold and they cut it afterwards, leaving a mark.

I wonder why they donât put the injection point into the âlegsâ which the TIR uses to sit on the PCB⌠Or keep a 2mm âwasteâ point, which is then shaved off with a knife, instead of just snapped off like here.
By spending 10ct more per TIR Iâm pretty sure it could be avoided. But on the other hand it does not Impact performance, so⌠Eh.

Does the IF22A lens have legs ? TIR lenses useed in flashlight usually donât.
Yes, thatâs right. But, in manufacturing, they could have a step that separates more cleanly and polishes off any jagged flange. Of course, this is cosmeticâdoes not affect the beam.
Iirc the one in the IF19 does, so I expected this one to have, too.
You guys are way too pedantic. Even the Acebeam L19 with it uber big TIR comes with a cutting like that. It contributes nothing to beam profile.
