I have no problem to activate turbo, however I agree that it can be hard when, for example, hands are cold. When the switch is released, there’s small pause before the light comes on. If you manage to half click in that time window, you’re in turbo mode.
I generally prefer lights without memory (starting on lowest mode) anyways. Is it at all possible to just disable the memory, perhaps at a hardware level?
Spaced the battery tube out with 2 copper sealing rings, cleaned all contacts with NO-OX, and on a 30T off the charger I got just over 25amps at the hit and 4710lms at turn on and dropping steadily… the tail cap and driver springs have some resistance they get a little warm around 30 seconds so does the light. The driver is a 3 FET with R010 resistor DD driver and the FET’s are scratched out but they look to be the SIR 404/800/Infineon style/type of FET.
Maybe try some Blue Gen 3 springs or just go for the 18awg bypass’s on the springs when I get the chance maybe this weekend…
Regarding the switch. Does the UI work the way it is listed on Neales website:
for SBT90.2:
Moon-Low-Medium-High
double clicks Turbo ,triple clicks strobe.
OR
Do you have to improvise like others have said, that is Turn it ON and then Two half presses for turbo. Supposedly can not be activated from the OFF position.
Here is what I measured with the Baby Blue LiitoKala (didn’t measure the voltage at the time) and I haven’t been really following this thread as of late… this is what I got…
1. 37lm
2. 505lm
3. 948lm
4. 1680lm
5. Dbl Tap - Turbo … (while in Turbo) Dbl Tap - Strobe
. It has memory so in lowest level, I double tap - Turbo - off, and repeated this Low- double tap Turbo off quite a few times and it never failed. I cycled thru the 4 modes many times, no hiccups. Got the light screaming hot, and repeated the above thinking maybe heat might make it wonky… never failed?
Can you try turning it off on turbo and see if it turns back on in turbo? When you do this, please check with your lumen tube, because high mode looks very similar to turbo mode. Can you do this 5 or more times
To be sure. All 5 of my samples have wonky memory. It will probably turn on in turbo mode three out of ten times.
How is that improvising? That's how I'd expect a reverse clicky to work. Either the driver memorizes turbo (to be determined I suppose? might be wonky) so you can access it from off once memorized OR, if it doesn't, of course you'll have to switch it on (full click) before telling it to go into turbo (double half-press/"tap"). A reverse clicky opens the circuit no matter if you fully click it or just half-press, to the driver it looks the same (it just loses power). It's just faster to half-press, hence probably many people have issues accessing turbo mode cause they're either doing full-presses ("clicks") or they're just not fast enough doing double taps - at least to me it sounds that way from the last few people reporting.
I have not had it happen in the low mode, but now that I’m trying it from the other 3 modes yes I had it memorize Turbo a few times last night…seen some other weird stuff also…
. Like this… turn on in each mode, dbl tap Turbo, single tap out, I get this…
. Level 1 turn on 33lm, dbl tap Turbo, single tap out of Turbo, 50lm, shut off, turn on 33lm.
. Level 2 470lm Turbo, single out 88lm, shut off turn on 468lm
. Level 3 888lm Turbo, single out 167lm, shut off turn on, 903lm
. Level 4 1600lm, Turbo, single out 328lm shut off turn on, 1606lm
