Can you measure Lux?
It will be very interesting, which dedomed gives more Lux.
No sorry… however I can tell you now the completely de-domed LED gives the brighter hotspot. While the partially de-domed one came very close to the same throw as an Trustfire X9 at 2.0A (it fell ~5% short) the completely de-domed one manages to equal the X9 at 2.8A… from this my guesstimate of lux is around 40-45K lux… I think the LED in the C8 was getting around 3.5A for both of these comparisons.
Hi Andi. I de-domed my X7 partially with a knife first and max was 127 kCd. With totally dedomed led it was ~ 160 kCd
With bigger hole in bottom of reflector and modification to put led inside reflector it is now 182 kCd! Yippee!
I also have measures of de-cuttet & dedomed, but it was interesting, if other people measure the same like me.
@Ledsmoke: i also have 182KLux, but that´s the lowest measurement. 
s. Now i try Aceton, but best method for me was/is cookplate. Yesterday i cooked another XM-L….works great.
The lowest! Wonderful :-)
Andi dedomed my EBL 6.1 Olympic-Torch
340 KLUX >)

What do you think would be the effect of dedoming a UF980L?
I dedomed it (dropped the whole pill in Acetone over the night) and the spot is certainly smaller now. Brighter.. I dont know. Have to wait to get my camera back so I can take some beamshots.
I just dedomed my X6 out of curiosity, feeling satisfied with the knowledge that I can just easily put in another SST-90 if I don’t like the outcome.
This is an SST-90 btw:
It now has a pretty yellow tint, quite ugly but I’ll see tonight how the colour rendering goes.
It now has 870 lumens (calculated form ceiling bounce against my 7g5-v2).
It now has 67k cd. At 2 meters, the X6 has a bigger hotspot than the 7G5-V2, but further than that it becomes smaller.
It was probably the easiest dedome job I have ever done. This really is close to 100% success rate as the whole dome just comes off.
I now have been motivated to mod the driver again. Huzzah.
Did you measure lumens/cd before mod?
It was 45k cd, 1300 otf lumens before mod.
“just comes off”? Which method did you use?
I think luminous lenses don’t have that gel layer in between so they come off clean.
Thanks. Looks like the amount of lumens traded off for throw is about in line with what can be expected.
@ slewflash: You should really try to measure that at 10 meters. My X7 gets me something like 116 kCd when measured at 2 meters but does ~180 kCd when measured above 8 meters. Just FYI
Good idea: I measured it at 10 meters and got a reading of 73k cd. Took more readings until I got 3 concurrent readings at 82kcd. Better than my dedomed STL-V2!
Also to the: there is some sort of retaining ring which goes around the dome. I have no idea as to what it does, but if you put a knife in one of the 4 corners of the ring, and very slowly and gently pry the dome off, you’ll see an air bubble, and then it’ll just pop off. It’s very similar to pulling a screen protector off a screen.
I went outside and took some beamshots. After they’re uploaded I’ll post them here.
Also note that when pulling off the SST-90 dome it comes off extremely clean. As in, the surface left behind is so damn smooth, more so than a baby’s bottom.
EDIT: Here are the pictures, 7G5V2 first, then X6 second:
7G5V2 left, X6 right.
Can someone please do mouseovers? I still can't figure them out... : -(
You should try the Input format (under the text box) -> advanced editor-> insert/edit image -> advanced tab. You can edit the html manually for mouseover (just quote any post with them and follow the formatting), but the graphical UI editor is easier to use.
Yeah, do I put the HTML in the swap image section?
I just left everything blank except the two links which I put in the swap image section after clicking alternative image. But it doesn't work for me.
I'm just copying the HTML code from flickr: http://www.flickr.com/photos/83081118@N06/8105051798/ and http://www.flickr.com/photos/83081118@N06/8105037009/
You may need to include the default image on the first tab page. The way I think the javascript works is that it overwrites the "mousein" pic name on mouse-over, and flips to the "mouseout" pic when you move the mouse away. Kinda primitive but so's most of the web.
So basically, put mouse-out pic (jpg url) in the first tab image url box AND the mouse-out box, then mouse-in pic in the mouse-in box:
slewflash has it working below.
