Question: Is the extension cord compatible with a CREE XML T6 Headlight?
Document: It's exactly what it said it was. I'm fairly happy with it, I bought it for the extra extension cord that came with it. That I love.
Attaches easily and securely. The extension cord included allows you to carry the battery in a bike shirt back pocket. I found I do not need the extension cord when I tuck the battery into my Camelbak.
After a half hour of fiddling, I mounted this on the front of the helmet and it works great. You will need an extension cord that you can get with the head mount, because mounting the battery on the helmet, makes it about two pounds heavier, and not pleasant to ride in
The mount works ok but the included power cord extender does not fit :( So now I have to jury rig something to get it to work without a cord extender :(
In my experience though, my head is always at an angle when riding that this is not an issue in the least. Solid construction, easy to use. The power extension cable will allow you to store your battery in your backpack or wherever convenient.
When I get it, I will see how well this system applies to it.So far, I'm very happy with this headlight mount.
I have the ATC cree light. It came with a head strap but not one that was usable for a bike helmet. I got this for my bicycle helmet and it is great for that purpose. The extended cord that comes with it does fit the ATC cree light, but it's not an exact fit. I'm not sure I would use it to extend the cord, though it will work. The product does what I wanted it for so I am happy.
works really well and stays put on you helmet. It is very easy to put in and take off. Just great
up and down adjustment is OK - but kind of fiddly - straps are long, but you can cut those. At least on my helmet (bell) it isn't all that easy to mount without the straps interfering with the helmet padding. But it is simple and it works.
the mount works great once its installed, but taking it on and off leads to the straps catching onto the pads in your helmet. The velcro on these is some 22nd century stuff, and it holds much stronger than any other velcro I've ever used.Once you get over the pain in the ass install, its easy to use and durable.There are no instructions, and two other guys I know who have this both were installing it incorrectly.
Answer: yes
