Yes the shipment arrived. In the order I bought one of their ~$50US 5mW 405nm in that same host. With a single 18650 cell the output power was about 115mW with the supplied plastic lens and about 200mW with the head assy removed. With a pair of 16340 cells the output was about 185mW with the supplied plastic lens and about 275mW with the head assy removed. The only complaint I had was the clicky switch in the tailcap was defective so I had to use a tailcap from one of the extra hosts I bought. The other extra host also had the same problem, defective switch in the tailcap. I wrote the seller to advise of the issue, awaiting a response. Offered for them to send me the switches and I can swap them out myself instead of doing a return.

As for pictures, I'm on dialup internet, so I'm not able to upload any at this time. I have no plans to go anywhere with broadband any time soon as we're currently snowed in a bit here. You can look at my other thread where I posted pics of the host and internal bits.

The seller asked me to describe the switch failure in detail. Since I'm an engineer, I chose to treat this as if it were a failure analysis. I dismantled the switch and found that the spring in the bottom of the plunger tube had insufficient tension to overcome internal resistance and return the plunger. I removed the spring, stretched it a little bit, and then re-assembled the switch. Problem solved for now and both switches are now functional.

However, to really fix this issue will require going back to the switch manufacturer and having them use a better spring. Either slightly thicker wire or using a better tempered wire in the spring.

I got the module out guys but did some serious damage in the process. the module is trashed and now there is no use for it. its a big hassle to use the host because there is a lot of hard glue left over in the host after i took out the module and heat sink.

I made the decision to buy a host with heatsink from laserpointerforums.com but im not sure what to get. I got in mind an 18650 kit for a green laser... i dont know anything about putting together a laser so i need a kit that is extremely easy for 18650 batteries and for 150-200mw green..

these are my conditions please someone give me a hand.

Big Bucks? you are under estimating this hobby..

Going a little conservative, will be a 100mW This is a genuine seller and all his units are on spec..
