They seem to carry all the same stuff the Chinese eBay sites do, only much more expensive. 2.99 lbs sterling for a chrome plated brass module is a lot more than $2.00 each. If you have no problem with the Chinese stuff getting through you might want to just go to the source.
That is exactly what many, if not most handheld lasers are made from, if not purchased as a complete unit from a company.
Some members make purpose built hosts for a laser module, but thay are basically the same as a flashlight host!
Look through the builds from members here, and see how they make a heatsink to fit these type of hosts.
It looks like you have a couple of options, go with that Odic Force unit, even though it's not 18650, or probably easier, take a look at these 301-303 style lasers from Sanwu laser.
Those are about as reasonably priced as you're going to get.
@ day, forgive me for butting in, but if your worried about problems with shipping. As Bowtie mentioned Sanwu has a 301-303 style, that might fit your needs (or whatever style you choose) The thing about Sanwu is, for whatever reason, if it doesn't get delivered Sanwu will resend another unit at no cost. I believe Jetlaser does the same thing.
Send Sanwu a pm/email and ask, once they confirm, it should make you breathe a little easier. Hope it helps
Agreed, Bob, thanks for adding that guaranteed delivery point, that is another reason why someone like Sanwu would be a good choice in this case, they're reasonably priced, and the company isn't located in the US. :yh:
We'll see; I've exhausted my ideas, maybe someone else has some other thoughts.
