Hi, guys.

firstly, sorry for my english, it's very "thiny" when a write texts (and read too):D

I have read in this forum reviews for this light, and it's appears to be amazing in output and uses AA cells, in Brasil, it's IMPOSSIBLE to find 18650 cells with quality and decent price, TF flames 3000mha is around R$42 (ONE CELL)....

Back in the light, I don't understand some things in post of review of this light (my poor english attacks again), some posts someone says this light on turbo runs 3 minutes and change to high, turbo dont runs Continuously?

This light in turbo is much hotter?

And the more important question, where I can buy this light whith shiping to Brasil?

Thanx everyone.

Political comment removed.

Correct, the light will drop to high after 3 minutes to protect from overheating and possible damage.

Sorry, I cannot help you with the shipping question...maybe give going gear a phone call...see what they say...

 

[Bumble]

try "illumination supply.com" to see if they deliver to brasil :)

 

[CarpentryHero]

IlluminationSupply would be your best choice, fasttech is out of stock. Fasttech has affordable batteries though.

I put one site into google translate for you. ;;;....

at bottom of page you may see International Shipping.

I hope my link works for you.

Good luck.

So they should to say in description 3 min on turbo, not 1:45h:crackup:

Anyway, after turbo time exceeds, I can go back immediately?

thankx:)

If you wish to risk extreme rapid deterioration of the LED...yes. The likely hood of total failure is low...but on the other hand, I do not believe there is a performance warranty. Another words, should the emitter output be degraded by 25~100 lumen from heat damage, it will not be replaced.

So, the gamble is up to you, and the consequences are yours as well.

Myself, I use turbo as little as possible. Maybe 5~30 seconds at a time...maybe 1 minute at most.

Some lights transfer heat to the body well...some not so much. Regardless, I am of the belief that around 500 lumen is the max safe extended running level for these XML`s...and even then, I would not expect it to make anywhere near the 50,000 hours to half output claim..not even remotely close.

So, if you want over 500 lumen for extended periods of time, I would look at multi emitter lights...

Pm sent! , good luck:wave:

wow, finally I can post here lol, since last post my pc tries hard to bother me:laughing:

Bumble and CarpentryHero, thanks for indication, in IlluminationSupply ha EA4 neutral and they ships to brasil:)

Sarrat, this link has amazing things, this site is confiable?

thakx :)

Serious?:eek:

I did no think these flashlight would burn leds, and knew that LEDs could reduce our brightness, but no so much. This decrease would begins in what temperature?

This event only occurs in lights with turbo/burts or it applies to all lights?

I have an TR-3T6 and that olny have high mode, it may be damage in long time? (hours)

It's good to know how to handle a light. However, the EA4 has a good cooling design. It is a big hunk of aluminum unibody shell that wicks the heat away. Rather than just the head that gets hot, the EA4 actually has the entire body warm up. I have run mine on Turbo a few consecutive times, and the light only gets warm but not hot. There is also the consideration that you are only going to get the 800 lumens on freshly charged cells before they begin to sag and the lumens will steadily decline. You can use Turbo as you want, but if the head ever gets hot to touch on any light, then turn it down and cool it off. Holding a hot light in your hand is one of the best ways to cool it off.

I've decided to not use turbo and now only use high.

Lol...I wouldn`t go that far. The turbo mode step down, and as other have pointed out this particular light has a good thurmal pathway into the body....the light I will probable last longer if used as expected...then you would care about. 5~6 years from now...way brighter better lights will be out and this one will be sitting in your drawer unused lol. So have fun I say, we are flashaholics after all.

Just keep in mind resetting turbo over and over, and keeping thing hot for so long...not what the manufacture/design is intended for...and could result in some earlier than expected lumen loss...

AW: nitecore ea4

Actually the Light not getting hot is more likely an indicator for bad heatsinking.

The EA4 has a cost efficient design. The heatsink has only a very small ridge were it is in contact with the body. This design was not made for efficient heatsinking but to mill the unibody more cost efficient. While it probably is sufficient it is not a good design in terms of heatsinking.

The heat doesn't bother me, I just find that high is plenty bright and has decent run time.

I also hold the light in hands when its on:D

The decrease of lumens is too big? How long to start to decline?

thx :)
