I want to purchase a FireFox FF4 60 WATT HID. Need help please?

Ok the Vinh TK61 does a lot of lux but I don’t see 2000 OTF Lumens from it. Maybe 1500 OTF

I knew Alex GT would chime in.
Seriously Big C, order the darn light and pay for extra fast shipping with tracking. You could have a FF4 in your hands in a week and be wearing an ear to ear grin.
Just do it. Stop beating around the bush.
Is it that good?
Yes!

Oh. And most importantly the FF4 in BLF reviews does over 7K OTF Lumens

That’s freaking cool but it’s not a flashlight anymore. Not my style but I bet it does serous Lux

I wouldn’t get too concerned about having an extra bulb for the FF4. Normal life span is 1000-2000 hours depending on how hard you push it. I do not think 1000 hours total burn time at 40 watt setting is unreasonable.
The bulb alignment in the reflector is crucial and this is something you want a highly trained and meticulous type of factory tech/optical assembly expert to tackle.

In other words, no need to be overly concerned about reduced HID bulb longevity.

I have an FF4 too. It does project a very bright, very far and wide beam of glorious light…. more than any multi-emitter light I own (stock and modified).

But…if it’s the only light you will own (and I doubt it is), then it’s an impractical beast to use as it eats batteries like crazy with a 2000-lumen low mode and can fry an egg…

A flashaholic should own a good HID though…it’s a different animal, so to speak.

Go for it

Low mode-24 watts-is about 3000 lumens. Not 2000 lumens.
40 watt mode mode is a generous 5000+ lumens.

And yes, help me convince Big C that it is a wonderful flashlight.
Thanks Tatasol!

Glad that you like yours, It’s a beast if you need it.

Yes, I am aware that it exceeds the factory rating of a 2000-lumen low mode @ 24w, as well as the other modes for that matter, as tested by RDfronty, if I remember right.

Thanks for the concern.

As a former owner of this light, the 60W version, it was great, but has some serious issues;

1. Lots of issues with the battery carrier for many people. I had to send mine back for repair.

2. You can only enter turbo ONCE after which you must turn the light off in order to enter it again.

3. In a warm environment even the low mode will get too hot.

4. Eats batteries fast.

5. Once you do a turbo run, you will need to allow it to cool down.

6. If the light gets HOT, you will want to turn it off, preferably take batteries out, and it will actually get hotter before it cools off, so it's out of commission for ~10 minutes or so.

7. Like all HIDs it needs to warm up.

Don't get me wrong, I like it, and I certainly don't regret buying one, but having had it, I can't help but to think LED lights are superior in most applications.

If an FF5 with active cooling, and carrying 8 batteries instead of 4 came out, I would grab one, but until then the FF4 just isn't practical to me.

As an alternative, I very strongly suggest getting an Acebeam X60, dedomed, and with a current bump. You'll get ~6000 lumens from it, and ~500kcd.

A modded RC40 would also work, but the price tag would be steeper, and output not quite as high.

Wow! That is a lot of negatives! I learned more about HID lights by reading your post and others.

I would NOT even consider one just on these THREE points alone!

2. You can only enter turbo ONCE after which you must turn the light off in order to enter it again.

3. In a warm environment even the low mode will get too hot.

6. If the light gets HOT, you will want to turn it off, preferably take batteries out, and it will actually get hotter before it cools off, so it’s out of commission for ~10 minutes or so.

It is more than “Maybe 1500 OTF” and probably 100 lumens or so under my 2000 estimate. :wink:

Mine is updated from the V1.9 “Prototype” and is the “V4” version.It has a revised driver I believe RMM designed with thermal protection and driven a little more. It is probably 1800 to 1900 OTF! Hopefully Justin will get this version to test and verify output.

Here are Justins[JMPaul320] measurements of the PROTOTYPE.

which differences are between the 60W and the newer 65W version ?

I was PM by the maker of Firefox via Facebox.

Other than the cosmetic changes which are minimal. They use the same exact bulb and its said to drive the bulb slightly more current with the 65WATT difference. I was also told lux is unchanged and the lumen output is negligible.

Best,
bigC

That would make the 60W version more appealing if anything.

I once saw a photo of the 65w version and noticed that it has a stainless steel bezel, though I’m not 100% on that.

That's basically it.

On the 60W version there is threading though, so you can use a camera lens cover. You can probably just unscrew the steel bezel.

You have identical issues I face with my MTG2 copper custom builds. Run hot, too hot to hold after 3~5min, drain cells fast at 5A~7A.

The only difference you mentioned is the battery carrier needing service, but other than that I have exact same issues with my 40~50WATT MTG2 2D Mag builds. That’s why I carry 2 of them in my Wrangler. Use one for a couple minutes, than the other to let the first one cool. Kinda annoying to do it this way, so nothing new here.

Ill look into the ACEBEAM X60. thanks,
bigC

X60 also can't be left running on turbo indefinitely. Unfortunately there doesn't seem to be any ~3500+ lumen light that can be left on at turbo without overheating, or having the light turn itself down (TK76 for example will turn itself down if it's getting too hot, or batteries are running low).

don’t buy the X60 or X60M without asking… :wink:
