Nitefighter L1A angle head light for $12.79

Just bought one. Thanks ChibiM for letting me know about this deal. Other places sell it for more than double

I don’t mind 2 modes it is strobe/SOS/disco modes i detest most. if they are hidden out of the way fine i mean really who the hell uses strobe except to mess about. I carry a british military suplus firefly beacon http://www.ebay.co.uk/itm/FIREFLY-MS-2000-m-MARKER-DISTRESS-BEACON-STROBE-200ft-water-depth-/201165002173?pt=UK_Collectables_Militaria_LE&hash=item2ed65e55bd trust my life to a POS flashlight yeah right.

In about a week time they've sold 80units, anyone already received his/hers?

If so, please let us know what you think about it. Just to justify me buying one. ;)

Not in yet...

hmmm, pity. hopefully someone will get one soon and be able to let us know more details...

I’m on the fence, but want to know how the UI works, and impressions.

Got mine in, have no time tonight for a story, just a few pictures. Compared to another 1xAA anglelight I have, a Trustfire Z2, this is smaller and feels more like quality. I don't know yet how to get the reflector&led-board out, for now it seems pressed-in from the front and glued . The led must go, just like the Z2 it is too throwy for a headlight, it needs a XP-L. The driver is 15mm

That reflector is deep. It looks like the mcpcb is mounted on the back wall. Electronic switch. You further confirmed anodized threads. If that's a 17mm driver, then we FINALLY have a really nice and cheap headlight host.

no, 15mm driver, no detectable PWM on low (modes are high-low-strobe-SOS *sigh*), ledboard indeed sits on the back wall. Going to get the reflector out one way or another these days, it remains to be seen if that can be done without destroying things.. now really off to bed...

Thanks djozz, those are very good pics...at least we can see its guts... How can you turn it off? Only through all the modes?

Thanks for the report, looks pretty good so far

I really like the looks of that. If the strobe/SOS can be bypassed, even if just cycling it on and off, I will definitely be picking one up.

Ordered 2 about 5 days ago and got an email 2 days ago saying they were out of stock and didn’t know when they would be back in stock.

Seems to be almost identical to GSX 85 Lumen Angle-Head Tactical LED Headlamp reviewed at CPF.

And this one Cree Flexi CREE LED Right Angle Flashlight on Amazon, please see reviews there.

What is parasitic drain ?

The GSX is said in the review to have a terrible pwm on low, while I can not detect any in this one.

The parasitic drain I just measured at 60 micro-ampere

How about overheating mentioned on amazon ? (link to review)

BTW. Is there a formula to translate CPF rating to BLF one ? :slight_smile:

I do not see how a light can overheat on a single alkaline/NiMh battery: the driver struggles to boost the voltage and the output will not easy get over 100 lumen. The light will not be hotter than luke-warm and to kill the led it must have no heatsinking at all.

I really tried to get the reflector/ledboard out now and did not succeed. Either it requires so much brute force and heating up that destroying the light is likely, or I missed something on how the light is constructed. Is someone else more skilled/lucky?

I measured tail current on a mostly full Duracel (actually the one that came with the light): 1.35A, after boosting I guess there is not more than 300mA leftover for the led. The output on high is about 80 lumen, on low 13 lumen. On an Eneloop the tail current is 1.4A on high, 180mA on low, output is 90 lumen on high, 12.5 on low. (It suggests pwm after all, the efficiency on low is not much better than on high, but this statement is not backed up by any decent calculation).

I doubt that amazon guy made up that story, he stated that it worked again after it cooled down, so it sounds to be about the heat, maybe just cold solder joint… (no word there about killing the LED).

Regarding LED current, I have seen 350mA mentioned somewhere, but I do not remember where…

Perhaps something was wrong with his copy. I just ran the light for half an hour on an Eneloop XXXX, the flashlight hardly warmed up, after that the output had gone down from 90 to 76 lumen. I let it cool down for 8 minutes, then switched it on and got 79 lumen. Nothing drastic going on with temperature in my copy.
