The first XM-L T6 bin flashlights and P60 modules. This is the beginning

So what would be a good driver for one of these then running it at full output ? I would prefer to install one in my Surefire l2x extended 2x18650

well not to many drivers will take 8.4v.

the shiningbeam 2.8amp driver only takes 6v

Couldn't resist. Went ahead and bought the drop-in. I have a couple of empty P60 hosts that needed a little buddy.

Me too, but I ordered the C8, and I'm looking around for some XM-L LEDs now. The P7 drivers and a possible hoist are on the way ...Oh my, I hope my bank account will stand all this "Iwantone-mania" these days...

My pending orders:

DX, 5 orders

LT, 2 orders

KD, 2 orders

My new meditatation phrase: "I have all what I need, I don't need to order anything now."----- "I have all what I need, I don't......"

It turns out they don't survive de-doming but when properly heatsinked - in this case to half pound of copper, they can take 4 amps.

Thanks for the link. Thats some good reading. It seems that the XML will probably survive 3A dedomed if well sinked and 4A with the dome. Im very impressed with the 95,000 dedomed lux as apposed to 50,000 with the dome (@3A). As prices drop, this is going to make for many interesting mods. I just might have to buy a lambda 3D mag or one of his proposed kits. How's your 90 holding up Don?

That's not how I read it - I think he's saying that dedoming will kill it as it does for XR-Es.

But it wouldn't be the first time I've been wrong.

This seems wrong, that's not how I understand the optics. Most likely he had the wrong focal length with the dome on.

I think the dome is at least partially a beam spreader to get the125o beam angle. Like the SST LEDs the "intrinsic" beam is narrower.

this may explain some of the dumping that's been going on .

An LED that may make everything else look lame .

didn't expect that

Yes, but even with a wide beam, it only means a larger hotspot (to the detriment of spill), not a brighter one, similar to xp-e vs xr-e. It does, however, change the distance to the image of die.

Get a deep enough reflector of appropriate diameter and focal length and you'll focus anything,

I was already assuming optimal focus for the remarks about hotspot/size. I said that he got the measurements he did because it wasn't focused as well for the domed measurement as the de-domed one.

The other possibility is given the measurement are made at non-infinite distance, one is focused to the meter better to provide the larger number.

LOL! I just read it again and still believe the dedomed (say that 3 times fast) was stable at 3A but got killed at 4A. Yeah I know... it needs much more testing on the bench, and over a much longer duration. For the price of XM-L's, a few shortened hours of life wouldnt matter much to me. Besides, im beginning to love my soldering iron! I have a MRV that I popped the dome off of (XR-E) and it has lived many hours of continuous use at 1.6A. Maybe its the luck of the draw, and also how well sinked the emitter is. Either way, this new emitter seems to be putting some of the anticipation back into our hopeless sick disease.

You got it!

Hopeless disease is about it....

For the price of XM-L's, a few shortened hours of life wouldnt matter much to me.

I think the more immediate risk to de-doming is that the gelatenous stuff that's the under dome becomes unprotected and also host to the phosphor. I de-domed a cree and even after immediately putting it back on, it wasn't quite the same as before.

Like you, I removed my dome by accident and tried to stick it back on. The beam was so ugly that I just removed it completely. I took a toothpick to the gelatinous stuff and it was easily removed.

I will see about ordering from Ebay , [ bare emitter ]

The P60 pill is $20 now ... So you may want to buy a 502B for $25

the 16mm base will be ok for P60 builds , but for smaller EDC lights ?? , 14mm would be better ... Just waiting to hear back from the ebay seller ....

let us know!

i want 14mm!!!

ill buy a crap load!
