I recently got in my MT09R.
none of my batteries fit properly and I couldn’t find my magnets. I’ll be able to more thoroughly test the light once I sort out my battery situation

Are you using button top high drain? That is what this light needs.

I was planning on testing with some 30q+small magnets as a spacer, or with my high drain Keeppower protected cells (although not on turbo for obvious reasons!). I couldn’t find my magnets anywhere and the Keeppower cells are way too long, so testing was an interesting prospect.

I’m getting some button top 30q to feed this long term, the other cells I have on hand I had planned on using to make sure it isn’t DOA. It does function.

If u r in US, illumn sell 30q button top for $5.5 each.

It might be worth it to invest in a simple soldering iron. With some rosin core solder you can solder blob your own cells plus a lot more. Every flashlight enthusiast should learn to solder. Plus there are tons of videos online showing the techniques.

NOT SURE WHY THE TURBO DIDNT STEP DOWN THE SECOND TIME? I SET MY IWN TURBO TIMER, AT FIRST IT STEPPED DOWN TOO FAST, WASNT EVEN HOT, THEN HIT TURBO…AND DIDNT STEP DOWN…SAFTY HAZARD.

Are you using the timed stepdown?

I’ve never used the timed stepdown option, but in checking my notes for the Q8 (uses similar NarsilM v1.0 instead of v1.3) the timed stepdown only happens once. If you kick it back up your basically overriding it. I bet that is what is happening in your situation.

I’ve always gone with the temperature based step down on my Narsil lights. Or just use my hands to know when to ramp it down.

I did Temp step down. In my vid you can see.it dropped from turbo fast, wasnt hot…hit turbo again…never stepped down.

Here are some notes from the Q8

Thermal Monitoring and Protection

The Q8 has two options for thermal protection: timed and temperature sensor activated stepdown of output. The light’s factory default setting is timed for 3 minutes.

A timed stepdown will occur only once, and works a little different in ramping vs. mode set operation.

In ramping, if the output level is above about 42, the output is dropped to 32.

In mode set operation, only if the mode is set to max (full power), it will drop down 1 mode, so it’s dependent on which set of modes is currently active.

Thermal stepdown is more involved. In the configuration UI, if you choose “Temperature”, and click before 5 seconds, it will use a preset temperature of 55C as the threshold, but can vary up to 5C from unit to unit. If you wait longer than 5 seconds, then your next click will define the temperature it will use for the threshold. Roughly, you should wait until it’s approaching unbearably hot to hold, and use fully charged cells to get there quicker.
Once the threshold is set, the temperature will be monitored while the light is ON, and when the threshold is exceeded, the output will be lowered as follows:
For ramping: 17% drop by level (where level is the ramping level of 1 to 150) For mode sets: reduced by 1 mode

Adjustments can only happen a minimum of 45 seconds apart to give the temperature sensor a chance to drop after an amperage drop.
In ramping, the drops from max/turbo will be as follows: 1st: 100% (150) to 55% (125) 2nd: 55% (125) to 31% (105) 3rd: 31% (105) to 14% (88) Drops will continue, but stop occurring once it reaches about 150 lumens, or 0.35 amps.

I was in ramping…so it seems you have to wait 45 sec to hit turbo again so the sensors can adjust.

Did you follow my video? The light turned on to turbo and you clicked when it felt hot enough?

Also, make sure you start off with a completely room temp light. If the light has already been on turbo shortly before, the internal parts will still be hot while the external parts might feel cool and this can mess up your settings.

You have a video? I will have to be carefull with this light…might just use stock turbo. Thanks

Maybe? I’m not clear on it.

From my understanding, the light will do it’s first stepdown at your set temperature. Then it will not check the temperature again until 45 seconds have passed in order to allow the light to cool a bit.

I know Texas_Ace had a tough time setting the thermal limits on his hand built and tested drivers he made for the earlier lights.

The MT09R is not like most lights. It heats up way faster than a normal light due to the extreme amps it pulls. Having the temp sensor built into the driver, while practical for most lights, is borderline usable in these lights.

I bet Texas_Ace can shed some more light on the situation.

I wonder if your right, maybe TA will know, i juat want to be safe…and OTHERS also, YES she heats up really fast.

I watched it…thats how i did mine, glad i didnt burn anything…lol…i was thinking TA snt the vid to me.

Like Jason said it would seem that it was in timed step down mode from how you described it, in which case it only steps down once IIRC.

I have kicked thermal step down back to turbo countless times and never had the thermal protection not kick back in on any light I have tried it on, which is hundreds at this point.

I would do a factory reset on the driver (the instructions are in the manual), then try the stock thermal protection as is and see what happens. If you have an IR thermomotor that would help.

It is possible that your MCU temp sensor is bad but unlikely.

Also, for the record, this light on turbo should heat up very quickly, maybe 30 seconds on turbo. That is the nature of a 150-200 watt flashlight in this form factor, nothing that can be done about that.

I’ve been planning on learning once I have space to do so.

Interested in a XHP70.2

I did the Thermal Stepdown, were it goes to turbo and you hold it to your desired preference.then shut it off… but i will reset it. Thanks

Make sure to do it on a room temp light.

If the inside is still hot, but the outside is cool, it may set the temp limit higher than you realize.

hi

I did not receive a coupon yet, but I’m still interested
