Lookin for host

Hey, I'm planning to build a 150 mW + red laser. For the moment i've found at modwerx an LPC-815 diode in a module
http://modwerx.com/shop/index.php?main_page=product_info&cPath=1_2&products_id=13.
I got a rkctsr driver and two 3.7 volt 18650 batteries. Now I need a host and a heatsink. I'm thinking of using a Dorcy Jr., but they're quie expensive and I don't know if the 2 batteries will fit. Anybody got a good and cheap host and heatsink that will fit all my components

you could make a labby? And substitute the 2 18650s for 4 AAs. Thats the setup i have. Its pretty nice. The link to the labby heatsink is this:

Its the last one on the list. An aixiz module fits in it. If you have any questions pm me. I'd be happy to answer them

Is a labby a flashlite :-?? Where can I get it, and can you please see the module I want to buy to tell me if fits?

I have almost the exact setup as you do except it is a lower powered diode (~220mW)

It is like a labby. It fits an aixiz module. You can get it from the link. It is 15 dollars but shipping is like 6.50 or something. It is worth the money though. It looks much more professional than just a module
