who is buying me a XP-E2 Torch led? Update: DBCstm did, test is in post#81

There’s an XP-E2 Torch going behind at least 2 of them.

What do you mean any free shipping sources for “it”? Usually shipping is something I expect to pay for when I purchase something of quality. Confused. ?

Maybe he thinks on China vendor.

They are really nice. I just wanna bite them (maybe I am crazy? :) )

Is the camera flaring the focus of that image? I mean, I’m giving benefit of doubt that it is because of the picture luminosity. What if you use a faster shutter/higher F#/lower ISO on the camera to capture it? Just curious if the “dots” on the phosphor become visible.

Hi MEM / Tom / LI

Sorry for my late reply too :).

Just some feedback on my experience with gas dedoming.

My first issue: The dedomes are not as clean as yours.

Your dedomes seem to not leave any sort of silicone residue on the base. Its as if my first dedomes were ‘cleaner’ than the ones that followed over time. I’ve used the same gas over a period of 3-4 weeks. After removal from the gas I soak the led for 10-15 seconds in surgical alcohol (to get rid of the gas smell ASAP) after which I immediately start to remove the remaining residue with fine tweezers. Can the efficiency of the gas to dedome degrade over this period of 3-4 weeks? I have not gotten to the point of replacing the gas to verify this.

My second issue: I’m experiencing smoke being generated from the LEDs after dedome and initial testing. This does not happen every time. 1 out of 2-3 LEDs does this. At first I was not aware of the issue, thus having the smoke being generated in assembled lights, which is really not nice. I then started to run the LEDs after dedome for longer until the smoking stopped.

Some further comments…

  • I use 95 octane unleaded fuel (South Africa).
  • Regarding the claims around more greens in the tint. I have not experienced this, the tint was consistent and predictable. I’ve dedomed XM-L, XP-L & XP-G - never left if longer than 2-4 hours in the gas.
  • I’ve found some white residue on the solder used to reflow the LEDs. Not a big issue.

At the moment my preferred method of dedome is still with heat & removal by scalpel. Its a 50/50 in terms of how clean the dedome is. I have a fetish for clean dedomes which I’ve not mastered yet! I’m still looking for that spot on method to get constant clean dedomes.

I have some old olympus 14mpx camera. Auto settings and point and click.

And yes small dots on emitter surface are almost not visible at 3m distance from wall (that wall on my pic is blueish)

If I compare it to 1503 lenses(another 50 mm aspheric) 1503 has larger main beam, and emitter dots are more visible than on B158 lenses. But it seems this is not crucial when it comes to throw :) . So B158 lenses has smaller main beam and better flood mode while 1503 has larger main beam projection when in fully focus.

1503(left), 280 kcd and B158(right) 340 kcd... Djozz made that pics. Plastic(acrylic) lenses wins over glass one.

Look at this thread post 45.

Edit: B158 lenses are really special... 340kcd results (we all got similar results when modded, which means they are consistent in performance, while uniquefire 1503 is best pick...) is something I was getting with 1504(67mm aspheric) year ago :) .

So yes it is probably possible to get high quality acrylic lenses from China vendors.

places i can buy it with free shipping or cheap shipping. (dont want to pay 5x the price of the led for the shipping)

The only place I know is Mouser. Since I have lost my remaining Torch leds and am also interested in a few more, perhaps I could do a little group buy on them, if I buy 50 of them, it is free shipping. The costs would be $1.62/led plus shipping to get them to people interested (~$1.50 per letter, no tracking/insurance).

Anyone interested?

Yep, no troubles reported here in their shipping department!

Mouser shipping fees for overseas is 25 dollars, however small the order, and we are budget light forum, you see ;-)

I’d heard of this model in a few Fenix ads for their new torches, but I didn’t know of its die size being the same as the XP-G2. And considering the XP-G2 is easily my favorite emitter considering throw and efficiency, this is a major win for the E2!

Can anyone please point me out to the posts where they compare to other emitters? I’d like to see how this fares vs. the XP-G2 and the XP-L HD.

XP-E2 is a lot smaller than XP-G2... At least my R5 XP-E2 collection. Or I missed something??

It’s listed as 3,45mmx3,45mm on CREE’s website. That’s the exact same measure as the XP-G2.

MEM and DJOZZ??? Is that true?

Mine are small. I would not want them in 50 mm aspherics even with precollimator lens I use (almost 100%bigger die projection). They are excellent in smaller aspherics of course.

The XP-E2 Torch has all the dimensions of the normal XP-E2, so will fit XP boards. The die is 1x1mm, that 2.2 times less surface area as the XP-G2 die.

I was afraid that is same as old one :) Thanks.

Derp. :Sp CREE doesn’t mention the die’s size, only the whole emitter’s. My bad.

The DIE of XP-E2 is a lot smaller than that of XP-G2. Package size and footprint are the same (XP)…

EDIT: Sorry guys, I haven’t noticed the last three comments, Djozz made it clear already.

I think we already found that out from the last 3 comments :stuck_out_tongue:

EDIT: Ninja’d.

yep, sry

I just wanted to post my thoughts on my visuals of the XPE2 Torch LED. My observations are based on a Carlco triple build.
After a few days of observation, something about the colour temperature seemed odd, until it struck me. It’s not cold, it’s not warm, and it’s not neutral. I see no hint of any extraneous colour…blue, red, yellow, green etc… The only classification I would give this emitter is “flat white”. I just don’t get any sense of temperature or tint, just an absolute flat white beam.
