Fire Foxes IV FF4

[edgar]

ah thanks i saw it , its a bit expensive , i ll wait untill they receive my broken one and replace it
Its been almost one month since i sent it ...

Got my light from Lips a couple of days ago...very compact and bright. Anybody know an easy way to unscrew the inside bezel to get the lens out. I was thinking of running mine without the lens to avoid the initial potential of build-up on the reflector.

 

[edgar]

there is no deposit to worry about , i would not open it , in fear tu put some dust in there or other stuff and have to wipe and scratch the reflector .

Hi,

I've got my Fire-Foxes FF4. It's amazing HID. But Unfortunately It was working just 20 min. Now When I am trying to turn on it, The HID lamp just spark and I hear high frequency noise. I use brand new Panasonic NCR18650. If somebody had the same problem ? What can be a reason of the issue ?

Thank you for your replies

I had an issue with my battery carrier. On mine it would just cut out after a little bit but if you unscrew the tailswitch a little bit it worked fine. I ordered a new battery carrier but I was also able to fix the one by taking it apart and tightening one of the screws for the columns that would break contact when the tailcap was screwed on all the way.

 

[edgar]

make sure your batteries are fully charged .
This little light dont have alot of runing time tho.

I couldn't find reason of the issue and sent my flashlight back to the seller

Just looking around at other threads and on several other forums. There seems to be a high number of failures on this particular light. How reliable are they? I couldnt wait to get one but now Im having second thoughts.

Mine also had a battery carrier issue. Took it appart and checked all the screws and couldn't locate the problem so I ordered a replacement carrier from lips on here and it works great now! The indicator leds are also upgraded and brighter on the new carrier :thumbup:

I would treat reflector and head assembly like an operating room if you want to keep it it tip top shape. A slight film on the glass, if it even occurs, is way easier to deal with at the time it needs addressing. Once the reflector is dusty, or worse... it will likely never be the same.

Runtime

Just curious what people are getting on their runtimes (Panasonic 3400mah batteries)? Either at 24W or 40W

I can't quote runtimes on mine, as I have never run it down all the way, but I would advise against using NCR18650B's (3400's). The light is meant to be used with unprotected Panasonic NCR18650PD or NCR18650PF 2900mAh cells, which are a hybrid cell that have less voltage sag at high currents.

Not my testing but someone did one...



Runtime Test

Sanyo 2600 24W 55min 40W 40min
Panasonic 2900 24W 65min 40W 55min
Panasonic 3400 24w ? 40w ?

Guy I sold one to ran it continuously at 60w. Not sure what batteries he used. Got 7 min at 60w... (3 min + 3 min + 1 min)

Panasonic 2900 mah 18650PD true 10 amp batteries should give most run-time on High Output levels

Fire-Foxes advised me today you can get 75min run-time with 3400mah batteries, but the light would technically be too hot to hold.

Does anyone know how to take out the HID bulb ?

Since this light has a 67mm thread on the front, I was looking for some filters that might work with the light. I called the optical experts at B&H Photo and told them my high temperature application. They recommended the following filters made in Germany (high end). The filters can be purchased at B&H Photo, Amazon and other photography shops. I am not saying these will work, but I am going to try a UV filter and apply a glass etching compound (Armour Etch) to create a diffuser. Just sharing some information for consideration. I sent a copy of this posting to Fire-Foxes for their opinion. If I hear anything back, I'll make another post.

I purchased a clear B+W 67mm UV Filter and turned in into a Diffuser for the light.
I used a glass etching compound found at most craft stores.
I did consider using a Hoya 67mm HMC UV(c) filter, but I did not think it would stand up to the heat.
The B&H Photo expert I talked to said the B+W would be a good choice for a high temp application.
Below is a picture that shows both filters. The Hoya weighs 1.8oz and the B+W weighs 2.9 oz.
The B+W Filter is much more robust than the Hoya, and incorporates a high quality glass with a brass ring
which is resistant to heat expansion (unlike the Hoya filter).

I ran the light for 10 minutes with the Diffuser on it without issue. The light was pretty hot by then.
No damage to the light or the filter. The filter easily unscrewed after the light cooled off.

I think the B+W Line filters should work fine with this light.

Per an earlier post, B+W makes a red and yellow 67mm filter.
