UF-1504, 1503, 1505 - multiple LED's tested for throw (just what you have been waiting for!!!)

Yep very narrow.
here is very quick un edited in camera jpg shot indooss just now on my bed.
I have two of these , identical, one is set to max zoom, …just about to drop off the thread, the other max flood.

I have shot a load of others, of the pill etc, that I will put up on the other thread I mentioned earlier

OK, so they have sent me two new lenses…DHL on their way.

So the recommendation seems to be an XP-G2

what is the max safest current I can drive this at? I see 4 amps being mentioned before, but was this with any specific cooling? more than the ‘standard’ pill to body heat transfer?

the pill is brass, but with collars on it, so not maximum pill to case heat transfer unless I may be fill the groove with compound. and the thread also?

Any one recommend a buck driver that has NO components on the spring side? 17mm have up to 22 mm depth in the pill.
Like to run 3 series lipo Cant see one on Mountain Electronics, and a brief FastTech search did not reveal any either.

17mm buck driver, 3S input, 4A output, no components on spring side. I think that's something that doesn't exist! The pill is brass so solder something in.

Funnily enough I did solder one in on another pill, but though I’d ask the question , as screwing it/clamping ig with collar is so much easier if things go wrong

OK, then so can you point me towards a 3s buck driver in 17mm J can solder in that gives 4-5 amps

MTN-MAXlp HP

I’ll have to check the spec on that one again. I thought I read it was only good for 1amp, as replacement for OEM driver

How the hell did I miss that ! I trawled Richards site a few tkmes before pisting, and FastTech… doh

OK, so settled on the MTN Max HP as suggested, that I should have seen myself any way.

So now to choose the LED.

What I need to decide is which LED and what max driver current

Before I go and make a mistake can someone tell me if this will be OK, trying to go after max throw…tint un important to me at the moment.

From my reading this thread the XP-G2 seems the one to go for de domed. Or the XP-G3 ?

I guess getting Richard to do the de dome for me is the safest bet! I have had success de doming in the past , but have also killed two or three too.

I will be ordering from Richard at Mountain Electronics as he will be sending my M6 back shortly, so hope he can include all in the same box.

XP-G*’s that Richard has on his site are:
XPG2-1D
XPG2-S3-3D
XPG2-S4-2B
XPG3-S5-3A

I was planning on ordering the driver at a 4 amp max…could I go higher. This is in the 1508 host

Think I’ll be .running 3 series 18650’s ?

I have spare pills so will keep the original pills as standard and play with the others for comparison beam shots

Hopefully this tread isn’t dead…

I’ve bought me a 1405 and I’m about to mod it, and Mtn-maxi driver for sure…and probably this led:

Any thoughts??
And is there other things to consider?? Like new high current switch e.t.c.

XP-L V6 1A
Hot Dedomed – 107900 lx at 5.82A for 361 kcd

XP-G2 S4 2B
Hot Dedomed – 137000 lx at 3.76A for 458 kcd

XP-G2 S3 1C
Hot Dedomed – 127000 lx at 4.05A for 425 kcd

Can someone help me understand why the hot de-domed XP-G2 is so much brighter than the XP-L… despite drawing less current? Aren’t these two emitters using the same die?

thanks!!

XP-L die size is the same as XML-2.

Oh OK… got it. thanks

How about that mtn-maxi with 12v ramp to drive the xhp35hi in this tourch?

Any thoughts?

I run one of my three UF-1508’s with MTN Max HP with x3 18650’s at 4 amps.

really can’t remember what LED i used though. but it is one from the list in my earlier post…. sorry…and I never did my beam shots either. but 3 cells is great for a good long run time, and allows the use of cheaper cells …as they are all having less current drain.

I bought x3 1508’s and made a 1 cell, a 2 cell and a 3 cell version.

Sorry I can’t be more help other than to state the obvious that run time is increased :frowning:

That is what I did 2.5A to the XHP35 HI. Don’t remember what number I got.

Does Cree make a factory de-domed XP-G2?

For reference I built an XHP35 HI 1504 and at a bit under 3A it does 250kcd for 1000m of throw.

In other words it best to go for that xpg2 s4 2b…

Mtn-maxi hp 5.1a driver and this led in an uf-1405 should be a hell of a tourch I belive! :wink:

Texas-Avenger: do you have a driver that will do me good? As in the specs mentioned above…
Pm. me if so, and we could do some business! :slight_smile:

Buck drivers are a black art at this point. I kind of doubt that we will be able to improve much on the specs of the mtnmax…

For max through the XP-G2 is basically always the best option, I just don’t like the low output so I go with XP-L HI or XHP35 most of the time.

Do you have a suitable driver for my uf-1405 (2S 8.4V) if I would go for an xhp35hi then?

I belive in that led, but It seem to be lack of “juice” when in use with a boost driver…am I right?

The XHP35 needs 4S, you would need to use 4x 26350’s like I did.

I used a Texas Avenger driver for mine. Zener modded (but I now have an LDO PCB listed that I would use). It is just an FET only driver as I am using it but with the duty turned down to around 75% it works great. RMM sells some drivers that would work as well, it is nothing fancy.

Now I do have a driver I am prototyping that could really work well for things like this but it still has a ways to go before it is ready.
