"Supercharged" FENIX P3D/Q5 Outshines ALL Others

[brightnorm]

Some of you may remember an earlier thread titled "Turbocharged Fenix P3DCE Outshines All Others..."
http://www.candlepowerforums.com/vb/showthread.php?t=166050

This new thread is the next "evolution" of that older thread using recent LED upgrades. In the older thread I put a Fenix L2D 3v head on a P3D 6v body with extraordinary though potentially hazardous results unless the runs were very short to avoid excessive heat buildup. The purpose of that thread and this one is not practical, but simply fun for brightness fanatics. (Though it also suggests what we may expect with future superbright LEDs.)

For this thread, I put a Fenix P2D/Q5 head on a P3D body and the result was gasp-inducing, truly like "a flamethrower of white fire". The "regular" P3D/Q5 looks almost dim compared to this new monster.

I don't have a camera, but others posted pics in the previous thread, and I'm sure some intrepid souls will take photos for this one.

Remember, if you try this be very careful not to allow the head to get too hot. Limit the runtimes, and it is probably best to do this outdoors.

Have fun and watch your eyeballs!

NEVER KNEW ABOUT THAT THREAD, NOT SOMETHING I WANT TO TRY BUT DAMN

um... all the CREE fenix heads are exactly the same except the engraving on the side. so a P3D Q5 is exactly the same as an L2D Q5 head on a P3D body.

The P3D head is a buck converter. The P2D/L1D/L2D are boost converters.

I wonder if that is driving the P2D's Q5 at close to 2A.

ah, so now it just goes into direct drive?

Incorrect.

Brightnorm

 

[Sir Lightalot]

Incorrect.

Brightnorm

Yes, i had forgotten that the P3D has to lower the voltage and heads that don't have that go into direct drive making them really bright correct?

 

[brightnorm]

I can't answer technically, but if you have a chance to try this I don't think you'll be disappointed. It may be the brightest light of its size in existence at this time, although admittedly, it isn't a practical light.

I'm looking forward to someone posting comparison photos like those that appeared in the previously mentioned thread.

I would like to see how long it would last

 

[Albinoni]

So how many Lumens does this baby push out now ?

 

[I came to the light...]

So how many Lumens does this baby push out now ?

or, more easily measured, what is the center lux?

 

[Albinoni]

Are you using 2xCR123A batts now for this beast.

Who knows might be bright enough to light up our cricket gorunds here in Oz for the matches

 

[99SS-T]

What kinda runtime would you suggest? I understand 0 is the only safe number, still you did it successfully! GJ

I generally judge it by how hot it gets, usually less than 30 seconds. I don't allow it to get really hot. As I said before, it's mainly for enjoyment of our Flashaholics brightness obsession. It can also have a useful function to quickly and briliantly illuminate a person/object at close or medium close range.

Even though it isn't designed as a thrower I have used it to very brightly light up 5th floor windows on a travertine building wall (fairly light in color but surrounded by strong ambient light).

Hopefully, the P3D or similar size lights will have this capacity in the not-too-distant future,.

What if you had one of the 3 cell bodies from Fenix-Store? I wonder if that would make it even brighter...

I'd be surprised if that wouldn't just fry the LED instantly.

 

[jugg2]

If I had the money, I would try it myself. But I have to sit out of light purchases for a while, this is a very expensive hobby...

 

[Masque]

All right, I gave this a shot. (Thanks to my son, and his willingness to hand over his P2D Q5 without asking why I'd want it.) It did not appear any brighter than the P3D Q5 head did, but it got warm to the touch within moments. That is, after 5 seconds of runtime on "turbo" it felt similar to the P3D Q5 head after running on turbo for a minute or more.

Maybe I'll break out some 100% fresh 123s and take some beamshots tonight, just to be sure. Anyone interested in beamshots?

 

[jugg2]

I'd like to see some beamshots!
