DX now has XM-L's on 16 and 20mm stars.
Just ordered a couple. I wonder what will arrive and when it'll arrive?
Don't forget the UniqueFire XM-L HA-III Cree XM-L 3-Mode 750-Lumen White LED Flashlight with Strap (1*18650)
If you don't want to go the DIY route.
Could not resist either.
It is the same flashlight as Yezl M6. Yezl was sold at $39.90 but this one is less expensive.
Kaidomain had 16mm stars today. They are much cheaper on KD.
Why is price on DX 30% higher than on KD?
This is just a guess.
The folks behind DX and KD were partners (?Kyle and Jerry? AxShop) about 5-6 years ago. Both were much smaller then.
DX have grown enormously, and enormously bureaucratic as they have expanded. KD sort of bimbled along slowly and were notoriously slow to actually get stuff shipped out.
About a year ago they seem to have decided to compete with DX. DX are charging what they do because they can - like DX did to QualityChinaGoods it seems KD wants to do to DX.
To do that, they need to compete both on price and service. If DX decides they are challenging them, we can hope that they will rise to the challenge.
If not, then KD has always been more "flashaholic" focused anyway. If they can get stuff shipped out the same year as it got ordered and let people know what is going on then they can only do better.
That said, Manafont is showing promise though they are clearly a much smaller outfit.
I waited a good 3 weeks for my MTE SF-15 to ship but after that experience my every ordwer from KD have been shipped in no more than a day or two. This is just a two months experience I must say. Didn't have much problems with DX either. Split shipping saved me time for a few orders.
Back to topic, funny thing is, I just decided to get a Yezl flashlight (M6 actually) before DX had one of these under UniqueFire brand. It looks like it has a tough body and good three modes. Yezl M6 was shipping something like $39 + $5 shipping. So I can say it saved me a good $10 already (don't mention my paying a good $14 to a 16mm T6 from EBay those are now selling $9.5 a piece on KD), but I guess it will be worth to wait for another week to order a XM-L flashlight. Who knows, they may come up with something different. Like a 3x XM-L head etc,..
DX also have a xm-l light now: http://www.dealextreme.com/details.dx/sku.50463
May be a thrower with those lumens and the big smo reflector
Nautic Look at my post #1 I did mention this light
Very very very sorry! I did not see that. 
Expect the price to come down as more and more sellers get stock ....
There are also some new SST-50 emitter boards on KD. Now a couple of things start to confuse me. I were thinking SST-50 was an inefficient emitter that must have been driven at 5A to give a decent (~1000lm :)) amount of light and it would heat up very badly at that current. I re-checked some graphs and now see that at somewhere near 3A, XM-L can have a lower lumen/watt rate than an SST-50 and junction temperatures looked the same. SST has a higher VF than an XM-L, though. But with two batteries this shouldn't be much problem.
So, could SST still be the better solution for double battery configurations ?
It'll work, and work well, but you still have the larger die size and higher Vf on the SST-50. The XM-L is making about the same light from a smaller die size, which is very useful for torches as they are size limited.
The die size didn't look much bigger on SST but you are playing under mm with a small light, and any filing requirement is upsetting of course. And I didn't even think about using the SST with a single cell. XM-L has the great advantage of being a low Vf led, small (XR-E compatible) scale and cheaper than a MC-E. Oh XM-Ls seem to have better tints too, btw.
So SST-50 can keep it's place in some bigger lights, I understand. I were thinking if I should build one with SST-50 instead of having 3-4 XM-L lights, or I could get a prebuilt one if there is a good drop in prices.
