Sure, I am using 3 kinds right at the moment, and got a 4th kind on its way. They all hold 18650 torches nicely.

1st one, $1.80 each.

2nd one, $2.79 each.

The above two work perfectly on my bikes.

3rd one, $2.30 each. This one here, I used to mount the 26650 torch on my helmet. I used an extra velcro strap around it for extra support. Works fine.

4th one, $2.39 each. This one hasn't arrived yet, and I think this one will be the best. This seems to be a copy of the Two Fish helmet mount, the one they have on Amazon for $7 or $8 + shipping. I ordered 4 of every thing, as they all come with free shipping.

Again, the first two work great as you can see in these pictures..



Those are $4 torches in these mounts that run off aaa batteries. I have since ditched all of those, even though they gave fair lighting. I replaced them all with 18650 type torches. But, check out the mounts. They work. On these, if there is any movement of the torch, I put some small patches of rubber that comes with mounts inside until I get a perfect tight/secure fit..



The prices of these mounts are so small, that I always order at least 4 at a time. That way, if I pick a winner, I have some extra ones.. Shipping time for these is between 2 and 3 weeks.
