Pretty soon, nitro will have some BLF, copper stars in 16mm… :nerd_face:
Kaidomain XM-L2 drop-ins for the nice price of $11.99

Cree XM-L2 U2 1A 1400 Lumen 3.7V-4.2V 5-Mode OP LED Lamp
I wish they would say what kind of drivers. If anyone finds out please let us know. I’m sure I will be buying from one of these two, possibly both. If anyone has any advice please help fill me in.

I went with the Kaidomain 5 mode SMO. I just bought the one. I bought three of the hosts so now I have two more left to decide what to do with.
I went ahead ordered a SMO and OP 1 mode yesterday from KD and emailed them asking about the current. They replied to me this morning:
They didn’t update the pages for the 1 mode versions, so hopefully they are the same.
Sounds like it may be direct drive.

Thanks Lgr-45.
Interesting, thank you.
Hello Guys I have been reading a number of your posts and they have been very helpful. I would not have known about the new XM-L2 if not for BLF. I am defiantly a noob and need help choosing a drop in for my Surefire 660 classic. It currently has the original 6v P60 and a DL223AC Lithium battery installed. I followed the links you posted and the 26.5mm SMO CREE XM-L2 1800-lumen 3~18V 1 Mode LED Drop-in would be nice if it is compatible. I would prefer the 5 mode version but it shows a max voltage of 4.2. Any suggestions would be appreciated. Thanks!
You could get the 5 mode version and some protected sanyo 16650 from international outdoors, coupled with a good charger and your all set. 
I got a reply from KD today about their 1 mode drop ins.
They are listed as 1400 lumens, but this can’t be right with 1.8 A can it? I guess we will see :~
Thank you for the info. My EOTech exps3-4 uses a CR123 battery it would be nice to only carry one type. I appreciate your help and all the great info here. One more question. What is a very good charging solution for the protected 16650s. Thanks
No. They often list maximum lumens, or sometimes more. Its “chinese lumens”. Never trust them! 
XM-L2 should be around 1100-1200 emitter lumens @ with 3A to the led.
1,8A should give it around 770 emitter lumens roughly estimated…
You can toss out the 1400 lumens right off the bat. That was never going to happen. I wouldn’t be surprised if 1.8A is correct. With a P60 drop in that is about all you can run before thermal sag drops the lumens down anyway. At 1.8 your could still be looking at around 800 lumens which is a ton for a tiny P60. This is a list of the different LED’s and what they run at. 1.8 might be all you really want to run with a normal P60 for anything other than a short time anyway.

I expected that I would be swapping out the driver anyway but if the 5 mode is direct drive I will probably leave it as is. I didn’t pick the 1 mode because I guessed given the stats that it was higher resistance. Mostly because, if it can handle higher voltage than it must have a buck driver.
This was the driver I was going to put in. I still might.
I ordered a 1 mode 3-18v drop in on 03/06 from Kaidomain status Back-Ordered 
2 PCS Sanyo 2100mAh Li-ion Battery (Sanyo UR16650ZT) Protected(Black) from Flashlight-International Outdoor
XTAR WP2 II USB Charger on ebay…
This will be used in a weapon light mounted on an M4. I hope this config works together. My Surefire currently holds 2 3v CR123s. Thanks for your help Ian2381
Does lightmalls ship out their drop-ins?
It seems like KD does not.
Before I ordered the two different drop-ins from Kaidomain I knew I did not like their store from earlier experience with customer support. But why not give them a 2nd chance. (And I really wanted to try these :p)
Their site says. “Ship in 1-3 days business days”
They have now had 5 business days to ship it.
Status: “back-ordered”
Have any ones order from KD shipped??
The U3 drop-in I got from Lightmalls was underdriven. I’d trust Kaidomain over them to drive either DD or else pulling 3ish amps, although Lightmalls has some welldriven stuff. Their U3 C8 is a blast of light.
Yes the site says my order from almost 6 days ago is back ordered as well. I got an email saying it had shipped out but the site says otherwise so i’m not sure what’s up…
I emailed KD about my back-ordered drop in. I got this in response.
Hi friend,
please don’t worry about back-ordered, it means waiting for supply. we are arranging your order now and will ship your order as soon as it is available.
Have a nice day.
My updated status is Order Pending
