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

Richard, I want to be the first to buy one, when you make it. Donā€™t forget to de-dome! :wink:

Yeah. I'm planning on sticking it in a TK61, dedomed, at 5A. Maximum beam width at 100 yards is approximately 10 cm diameter.

Sounds perfect for the Uniquefire 1504/1405ā€¦.

:open_mouth: 10cm at 100yds!!!

LOL

Nice coiled tape of tiny little emitters. Purdy cool! :slight_smile:

Now, do I start testing or start shipping? :stuck_out_tongue:

The things Iā€™m most interested in are the Vf and how much the tint shifts with a dedome

Hey Dale, sent me a couple of them and The Sphere ā€™o Many Mysteries can measure thatā€¦

Shipping with right hand and testing with the left one?

Really be cool to see the stats that you can measure.

Iā€™ve got a lot of these to spread around people, speak up, donā€™t make me eat Ramxpe noodle soup!

$1.72 apiece, thatā€™s the price I got em for by buying 50. A couple of folks have spoken up but yā€™all need to clean me out on these. :slight_smile:

Yep, Iā€™m definitely in for 2. (yes, I know, only 2)

I have 4 in the gas.

Weā€™ll see.

Looking forward to the results!

Did you do any preliminary testing on color and tint?

What were these binned?

Gas? Blasphemy.

Correct me if Iā€™m wrong. I just looked at the Cree Product Characterization tool a little while ago. It has specs for the various emitters and there are three columns so that you can compare multiple emitters to each other directly. I chose: XP-G2, XP-E2, and XP-E2 Torch to compare. I see that the XP-E2 Torch is rated for higher amperage than XP-E2. But, other than that, the performance is not as good as the XP-E2, and not even close to XP-G2 when you measure in lumens-per-watt. The XP-E2 Torch also has a significantly higher Vf than either of the others. Really, what is the draw here? :~

Edit: I should say, total lumens output is higher than XP-E2 because of the higher Vf and being rated for higher amperage. But, really, is the XP-E2 that much smaller than XP-G2? Because, the lumens-per-square-mm would be the only advantage I can think of that this thing might have.

OMG! These things are TINY!

About an hour in the gas, I pulled em out and dome was sitting top but easily lifted right off. About to mount em on 10mm SinkPADā€™sā€¦.

Maybe a touch early on the de-gasing?
Looks to me like you lost a bit of corner phosphor on each dome, not enough to notice in a reflector light but maybe visible in an aspheric.

I thought you weren't using gas anymore.

The bond wires are on the corners, not missing any phosphor.

I was referring to these little patches of yellow stuck to the domes. Seems itā€™s a bit of phosphor coming loose from around the bond wires maybe?
