Fenix Rebel 100 fine print: "run Turbo for no more than 10 minutes"?

Does this mean the LED is overdriven or maybe the dealer just wants to make sure no dead Fenix's come back after a customer fries it?

Is this a manufacturer fine print or a dealer fine print?

How come this other site does not have the fine print about Turbo for no longer than 10 minutes?

It's most likely the light can't run that long otherwise it has bad heat issues. Yea mostly likely overdriven as their other lights. I'd steer clear of this one in the meantime as you don't want your LED going poop in a few days of use :wave:

I have had my rebel p3d's running on max with 2xrcr123's with no problem
at all. They do get hot understandably, but not so hot that I can't pick it up.
The rebels tend to have a lower vf which translates to more efficient,
less heat compared to the crees... at least the units that I've played with.

As always, it's best to have the lights in hand since your hands act as a
heatsink pulling heat away. Even on medium, if you leave it in your pocket
or wraped around a towel or some insulation, any light can get scortching
hot. This the nature of LED lights - since the heat is not emitted out
the front like incands, the little heat (compared to the incands) must be
moved away from the LED somehow. Thats why aluminum is the metal
of choice since they do such a good job.

I never understood the LED lights with rubber casing. Those LED's will have
a shorter life due to inadequate heat disspation. My two cents. :shrug:

If I pre-order a L2D 100 Premium today, when do you think (approximately) is the ETA (the flashlight arriving at my doorstep) ?

Whoa. I missed that (not around CPF a whole lot recently).

Is there more info on this available somewhere? Link?

Why?

I just got two Fenix lights in the mail from you today. Already considering more for future buys.

LOL! I knew there had to be a silver lining with my cherished incands!! :kiss:

Looking forward to getting the two Rebels I just ordered!

What experience and facts do you base this on?

I'm reading the manual the P3D came with, and it says "Under high ambient temperatures, please do not use the Turbo Mode for more than 10 minutes continuously, doing so may harm the battery and the flashlight."

To me that means when it's 100F+ outside, and you're in the direct sun, you may want to limit Turbo because it's so hot outside the light can't cool itself with the air. Good thing I never need a flashlight when it's sunny and hot out. If I do I'm probably somewhere cooler and DARK.

Or it may mean, if the light has been sitting in your car and is 150F from being on the dashboard, you may not want to run Turbo for a long time.

They don't say what high ambient temperature is. I don't consider 80-90 degree weather high ambient temperature.

If you are under normal or low ambient temperatures they don't say anything about running Turbo for long periods of time, because it should be fine, as others have proved.

Just wondering if that means this light is best used in winter when it is snowing and the light from the Fenix will bounce off the millions of snowflakes and light up the whole mountain. Serves as a hand warmer too.

Haha. I ran a test today where I had the P3D Rebel on TURBO for 6 minutes. It got up to about 99F. It was still warming up, but at a slower rate. The base of the body tube warmed from 71F to 85F after 5 minutes. So the heat was being absorbed by the whole light. The temp of my house is about 73F (it was originally in my bedroom which is a little cooler which is why it started at 71F). Maybe 4sevens can find out from Fenix what they consider "High ambient temperature" to be. To me that's over 100F, considering holding it in your hand is 98.6. I doubt they consider holding the light in your 98.6F to be high ambient temperature. They may well mean 120F+ or something hotter.

I doubt that holding anything in your hand will heat it to 98.6*F.

There is a reason thermometers are placed in the mouth, under the tongue, and other places....

Not in your hands.

Haha! Good point! BUT what if I have a fever of 104F and I need to use my Fenix to find my way to the medicine cabinent, or read my thermometer? Could my hand be 98.6 then? I just used my thermometer to check my palms and each palm shows a max temp of 96.1F.

So if the Fenix got to 99F tailstanding in about 6 minutes, it may have stayed cooler if it was in my hand.

96.1* is what it read? Really. I would have expected less.

If you are looking for your medicine cabinet or reading the thermometer, do you really need turbo?


Then again if you are maybe you will forget the head is screwed on tight and blind yourself.

What were you browsing particular 'mature' sites on the internet before you took this reading?

Seriously, when I shoot my skin (arm or hand) with a Fluke IR thermometer I usually get a reading around 91 degrees.

I get 81˚F.

Edit: I should mention that the room temperature was and is 71˚F and I haven't done anything physically demanding all day.

 

[Valpo Hawkeye]

I get 81?F.

Hhm. I keep my tools in my company van at the office, so I'll have to reshoot tomorrow for comparison. Now that I think about, maybe 91 is when you shoot your tongue. I'll post tomorrow.

 

[WadeF]

I'll chalk it up to being thin, high metabolism, good circulation, etc. I was typing a lot before hand so that maybe why. If it was the reason you mentioned I would expect a reading higher than 96.1F. :candle:

 

[4sevens]

Your profile says Texas. Assuming it goes out on the 13th,
I'd say the 16th.

Haha... LED lights can never start fires like some incands will in 3 seconds!

Well, there are also other variables
such as humidity, and whether the air is still or windy.
Air is an excellent insulator, expecially when it's not moving.
Try putting any of your flashlights driven at 400ma or more in your
pocket or in a towel in your suitcase. You'd be surprised how hot they get!

Whoa. I missed that (not around CPF a whole lot recently).

Is there more info on this available somewhere? Link?

I'm not sure of the exact reason, but the dealer posted somewhere on cpf about closing down.

It's dealer fine print. Keep in mind that dealer is going out of business

Torchworld who is not going out of business also has the disclaimer on their site.

I can only go by what the manufacturer's statement that comes with the P3D --
which gives a general warning without specifying ambient temperatures.
"Please use the Turbo Mode sparingly, due to it's high power consumption, an
excessive amount of heat may build up."

My interpretation is that it is more of the accumulation of heat rather than
the specific ambient temperature. Even if the ambient temperature is
relatively cool, the light wrapped in a cottom T-shirt will still cause heat
to rapidly build up.

Hi everyone,

I made a very big mistake and confused seriouslights.com with
qualityflashlights.co.uk.

To the Folks at qualityflashlights,
I sincerely apologise for this mistake. It was in no way intentional.
Again, I am sorry. Please forgive me.
