100F at night, that is crazy.

Here in Sweden we (or should I say I) are lucky if we get 1-3days on the whole summer over 31C (87.8F) in the shade. I say lucky because as far as i am concerned it can’t be to hot outside.
But then i can’t even imagine a lowest day temp of 37C Big Smile But call me crazy, but i think i would like it Smile

100.4F or 38C is the hottest it has ever been in Sweden in recorded history Wink

I always thought Sweden would be a nice place to move to, except for the cold!
Have you visited anyplace hot? High heat plus humidity can be harsh.

It is a great place to live in as far as a country & society is concerned Smile

Most of the year it is quite dark outside for flashlight adventures. But not now, now it is just way to bright most nights Sad Last year at this time i didn’t even own a flashlight, i had no idea i would miss the dark so much Big Smile

But it is a bit cold for me, i get very much affected by temperature, the warmer it is, the better i feel & as long as i keep my electrolytes in check & the more energy i get. I have found that as long as i supplement extra magnesium i don’t get nearly as fatigued by heat or humidity as i used to Wink

My problem is usually not the heat or humidity but the sun, because i have light skin & blue eyes, i burn way to easily if it is to much intense UV radiation in the sunlight, and because we only have UV radiation enough to tan 6 months out of the year, i have never built up a stronger resistance to it.

And no, i have never visited some place really hot Wink

When you say overheating at 60-90 seconds, are we talking about outch my skin i really starting to hurt now i need to switch hand or stepdown/turn off, or shit the wires desoldered themselves & it is shorting out the battery in my hand Shocked & the led slid off the mcpcb, kind of overheating.

Because the first is the fun :bigsmile: of running “hot” lights with lots of output, but the second is a much bigger hassle, when you are so close to the limit to the light destroying itself.

So what are we talking about here?

By overheating I really meant the dangerous, desolder-wires, self-destroy kind of overheating, but at 50% that is very unlikely to happen. Personally I like to keep these kind of lights, aka pocket rockets, in my own hands, not give them to friends who are unaware of potential issues when running those little rascals unattended.

I keep these lights in my hands and turn them off or lower the output when I feel it’s getting hot. Everyone has a little different sense of what is hot. Mine changed a bit since I got a Zebralight SC600L2. Before that, I would’ve felt that this is too hot already, but since it has a temperature regulation it must be safe, right? I basically don’t let my lights run hotter than my Zebra gets.

I’d vote for staying with 30s turbo timer but that’s just me.

I envy you.
I hate hot temperature.
Lot’s of sleep issues, even if I have a climatizated rom, I cannot make it cold as I would because I live with other people.
It’s not nice to have more than 40°C, and 85% humidity, not funny at all. I find myself much more accustomed going working outside with a T-shirt when there are 5°C than living @ home partially naked in summer.

For the magnesium stuff….I’m with you, also with Potassium

For the stepdown timer…30+ would be nicer than 30 but It’s a NO BUMMER for me, as you can always go down and come back up, right?

I am fine with 30 second step down for a good safe Turbo session. I would rather have this light available with “only” thirty seconds of ~1500+ lumens that I can use with the other modes, than a light that goes “phfffft” one day I am feeling froggy on seeing how much heat I can handle…

You can discus this endlessly, piling safety margin on top of safety margin, but it just needs a test, with a high drain battery, tailstanding, with high enough ambient temperature. The turbotimer can then be set at what the light can handle, 30/60/90 secs or whatever it will be.

I do agree that if getting this light  suitable for unaware (stupidWink) folks implies bargaining too much on the performance, then it would not be a true BLF-light anymore.

But it looks like we're on the right track for both kind of people Smile

Ultimately... Smile .... Whatever TK says she is going to do with the code is what is going to happen Smile I do not think any one of us in the group will not go along with her recommendation. If she feels it is too hot..then it is too hot.

Someone asked about LVP (low voltage protection). It does have that and even has a battery check feature in the hidden section.

I believe somewhere in this thread are all of the features but honestly I cannot say where. It is my fault that I did not include it in the OP. IF TK finds the time to list and post the features I will post them in the OP. With that said, the ability alone to go from 7 to 4 modes and reverse is the cat's meow. Even I, who likes mode memory, find that even starting on moon and jumping straight into max to be easy. That should even satisfy the 2-mode people Smile

What this light does not do is clean the house. LOL.

Think about it:

  • Max people
  • Moon people
  • 2-mode people
  • Bicyclists
  • Low Voltage Protection
  • Battery check

Like Dale said....this UI just needs to be implemented in ALL lights

It's the simple things that we take for granted that cost us the most

No, it just drops directly to the previous mode.

Thanks for the reminder. I forgot to update that after I added things to the code, so I updated it just now. Smile

A short(ish) list of the light’s features:

  • FET+1 driver for both maximum output and stable low modes, should do about ~0.3lm to ~1500lm on the stock light.
  • Standard-sized 18650 tube light host with good anodizing and (I think) BLF logo. Uses a reverse-clicky switch and can tail-stand.
  • Copper MCPCB with direct thermal path to handle the high power.
  • Two options configurable without opening the light:
    • 7 or 4 regular modes starting at ~0.3lm or ~10lm depending on the config.
    • Mode memory can be turned on or off.
  • Modes are evenly-spaced according to selfbuilt’s cube-root model of light perception.
  • Offtime-based UI which detects short/med/long presses to go forward, backward, or to the first/memorized mode.
  • Low-voltage step-down and shutoff.
  • Turbo step-down (timer-based, time not yet determined).
  • Hidden blinky modes:
    • Tactical strobe
    • Biking flasher
    • Battery check / beacon
  • PWM is fast enough to be imperceptible (19 kHz), and blends the two power channels to make tint shift gradual.
  • The MCU is flashable, and the code and driver designs are available for anyone who wants to modify them.

Approximate runtimes based on DBCstm’s power measurements and a 2500mAh IMR cell:

  • Moon: ~11+ days (TBD)
  • Low: ~3.5 days (TBD)
  • Med 1: 17 hours
  • Med 2: 6.5 hours
  • High 1: 100 minutes
  • High 2: 50 minutes
  • Turbo: 26 minutes (but not recommended for more than 60 seconds)
  • Tactical strobe: 53 minutes
  • Biking flasher: 5.5 hours
  • Battcheck / beacon: ~17 days? (TBD)

I'm really interested in this light. I've been reading the thread, but it's pretty long. Can anyone tell me the approximate level of the moon mode?

I know it will vary for different cells.

I'm just glad to see "our" custom firmware make it into a nice production run.  Everybody is doin what they are good at - from firmware to making drivers/lights. Of course TK doesn't make any $$$ on it - can't say Eagle Eye or BangGood are making much either, but if this gets pulled off where the majority is happy, we all owe TK something. I know she's leveraged some things from BLF or BLF'ers, but the majority is on her.

Rolz - thank TK, not me... Smile

At Least 60sec, please…

At my age, sometimes it takes me sometime to realize just what it is I am looking at:-)

90sec would be great, but thinking more about it (after reading other’s posts) – No stepdown would work for me too.

If I don’t forget that the pain in my hand means that I am being burnt:-(

The way that this light is built, I would venture a guess that it is able to stand more that I/We. – Great heatsinking will make the outside of a High-Powered light heat up FAST, if the Sink is well connected to the exterior.

Thanks,

-Chuck

I should have a sample to test tomorrow. I am usually able to get moon into the range of 0.2 to 0.5 lumens though, so it’ll probably be in there somewhere. It varies for each individual unit though, and also depends on the battery voltage… so any measurements I post will be approximate.

In group 1 with 7 levels, moon is so low as to be virtually useless (IMO) I have used it in a dark house late night, and outside. Even trying to see the camera settings up close and personal moon is so ultra low as to not be much help. I know there are those that will rejoice in this, and those that will groan. But really, it’s that kind of low…. easy to forget the light is still on because you can’t see the result.

In group 2 with 4 levels it’s not this way.

To rephrase it, those cheap little coin cell keychain lights with the 3mm tubular led? When the battery is almost run out? Like that.

When I initially checked the samples to see that they worked....

I thought the first one was defective because of the moon mode. It wasn't until I looked at the LED that I realized the light was on. I too find such a low useless BUT like you said there are many here that will rejoice at such a low. Hell, if your eyes are that good...you do not need a light Laughing

Besides Dale...we have our Max mode Tongue Out

It's the simple things that we take for granted that cost us the most
