Package #2 Courui Gray XM-L2

My first impression, this flashlight is made for big hands. Second impression this thing begs to drive an XM-L2 till it screams. 3 18650s in parallel would allow a hard driven XM-L2 decently long run times. Here’s the major component tear down.

I didn’t measure the head but let’s just say it’s big. The lens is glass but probably not coated. The reflector is a fairly robust piece of aluminum.

The switch stands just a little bit proud and I found myself accidentally turning the light on occasionally while handling it. Also the shroud around the button was loose and easily removed. If It is not tightened, would probably rattle loose. there are no O-rings protecting the switch from moisture. In fact there is nothing preventing water from getting into the driver board area at all.
Proud Button

There are two LEDs on the E-switch. I never saw them illuminated. I assume they are to indicate low batteries. There were two additional solder pads on the back of the switch that were not used so maybe the SMD LEDS have no function.

Lifting up the E-switch, it’s easy to see how water could enter into the driver board area.

Here’s the battery side of the driver board. I attempted numerous times to pry the driver loose but it was in there really tight and I just couldn’t get it to budge. Those wear marks are just as it came out of the box. So certainly somebody’s been twisting some batteries against that before I ever owned it. I’ll give them the benefit of the doubt and say that they were testing it with batteries.

I really wanted to get that drive board out so here’s where I got stupid. I inserted a screwdriver through the negative wire hole of the star platform and wiggled around until I was mildly sure that I was not on top of any surface mount components and pounded the crap out of it until the board came loose.

I really don’t understand why this driver board needs to be so complicated. It is only capable of switching to high and then low them off. Repeat. No memory, no flashy modes (thank God) Nothing else.

I pulled up the toroid to expose a chip that could probably launch the shuttle. Somebody smarter than me will need to explain why this thing needs so much intelligence.

I had a heckuva time getting the driver board back in because it’s such a tight fit. I finally resorted to a socket and a steel toed boot and pounded the heck out of it. It did fit.

Of course you’re all wondering whether this thing even works anymore after I abused the board like that? I can assure you it does. That persistent Blue dot with red Corona in my eyes constantly reminds me that it still works. Yeah, I accidentally hit the switch again right in my eye.
Did I mention that all of the threads were bone squeaky dry?

Moving onto the tail cap… Why would they design the board so that it requires a jumper and then, why would they then jumper it with a 26 gage wire?
Why no lanyard hole on the tail cap? OK honestly I never use lanyards anyway so I’m just being nitpicky.


Bottom line… This light has a lot of modding potential. I like that it has three parallel batteries. I don’t mind the fat grip, I have big hands. Dang it, another persistent dot in my eyes. Ive got to put this thing down. I’m not liking the switch. Too easy to accidentally turn on. Also this is not a light that I would throw in the pick up to bounce around and turn itself on regularly. Also would not be good for rainy conditions.
I need to look into what Osh Park boards are available with an E-switch that could push the amps harder than this board does. I’ll try to get some beam shots tomorrow. It’s bedtime.
