When I saw Rick's "special" I decided to take the plunge
Since the price difference was not really significant, I decided to go with his highest powered unit
I ordered a 3+W; two battery laser

At this point, Rick had no idea who I (the buyer) was ;)
I prefer to buy my review lasers anonymously
It prevents my getting a "cherry picked" laser and I don't "owe" the seller anything

Communication from Rick was good
We decided to go with the grey host, so I could use the 26650 batteries if I chose
The laser came with two, 18650's (with adapters), but it will hold the 26650's if I want to buy some

The laser arrived quickly via Priority Mail
The package was a bit "crowded", with little padding, but most of the contents are solid with no loose or moving parts
The laser and components arrived in fine condition


The package containd the host, two 18650 batteries, two adapters, the laser module, a charger, and some goggles
In this picture the module is still wrapped in the bubble wrap


Removing the bubble wrap shows the module in an ESD baggie


This is the module


The rear of the module shows that the contact disc is too small for the module. You can see that it is held in place by what appears to be epoxy. In addition, the soldering is a bit rough and extended beyond the threading a bit. One thing that Rick can do to improve the assembly is to change the size of the disc or the size of the hole to eliminate these gaps. Also, he should consider using a brass or copper adapter ring to solder the disc into. That would eliminate the messy soldering. It is almost impossible to solder to a large piece of aluminum. The heat is sucked away too fast to allow a good hot solder flow and joint

While this is not "pretty" looking, it is functional
For me, I don't care much about if something INSIDE is ugly as long as it works well
Once the laser is assembled, no one will see this part ;)

The front of the module looks clean and already contains the lens


You can see that Rick has this module marked at 3.2W


Here you can see the 9mm diode and how Rick has to grind down the rear of the lens nut to allow the lens to get close enough to the diode


I had to clean up a bit of the solder to get the module to screw into the host


The module does not screw down into the host very far
Its progress is stopped when the rear of the module contacts the inside of the host's bell


I understand that Rick has changed the design of the heat sink so that it is beveled on the rear shoulder. That change will allow the module to be screwed in a bit deeper

The laser looks and feels good in my hand. I would like the module to be deeper, but that is truly just a personal preference.


I topped off the batteries and did some initial testing to make sure that the laser survived the shipment.
It did.

I charged up a pair of AW 18650's over night so I could do the serious testing in the morning
I use a Scientech 365 LPM
My testing with the lens that came with the laser showed a solid 3.18W.
This difference is well within the normal variance when going between one LPM and another LPM.

I tested the output with a G-1 lens as well.
I had to put the G-1 lens into Rick's lens nut so that the G-1 could get close enough to the diode to focus the beam
I metered no significant difference between the T-1 (stock) lens and the G-1 lens

Overall, except for some minor aesthetic preferences and the bit of sloppy looking soldering, I am well pleased with the laser and with Rick's communication.
Glenn (Scopeguy20) even came by last night and liked the look and feel of the host.
Of course he was also impressed with the 3+W output ;)

+1 for Rick Trent

Peace,
dave

And so the first one is on spec! This is fantastic.

Why don't my customers ever pay me so I can get one :banghead:

Wow.. that really looks like the build I am after.
I like look of the host as well as the size of the sink.
+3W output is a big bonus

Dave, you're making me hungry for a 9mm build.
:tsk::evil:.... Wish list

Thank you for helping me out with the account problem this morning (night your time) !

+1 for you

I wonder if the driver is or needs to be sunk or is it sinked and if so how that is accomplished? What kind of current draw is that beast pulling? Can you take the screws out and let us see into the module?

I miss Daves reviews good job.

Thanks for the review. I am curious too what current the diode needs to accomplish the 3.2W output.

Nice detailed review Dave...
It seems to function well as it should with plenty
of output but the "sloppy" soldering quality would
put me off.
If Rick could clean that up a bit it would look much
more professional... IMO

thanks dave nice job and very fair review, to answer some question the driver does not need a heatsink it runs cool around 2.5A I sent a driver to dtr for him to test. I have fixed the heatsink to fit driver better and I have a Conductive Wire Glue/ No Soldering / Gun/ Iron / Solder needed will look better . I work to make my laser batter all the time as we all know 3w + is new I did rush it to get kits out people were on me to get them one out fast they could not wait!!!! I did rush it some .it did max out the laserbee LPM as dave hold some are off some I have found some are 300mw +- here is a video of my 700mw to 1w red laser 638nm to 650nm show the new heatsink and host http://youtu.be/UoETAyISZOE
a look inside the heatsink http://youtu.be/ytdJbMNMVfs

This was a great review, and I love the anonymous purchase! +rep if I can!

Ricktrent4, if at all possible could you use more punctuation when you type? I could make out some of what you were trying to say, but adding punctuation will help people understand what thoughts are grouped and it will be easier to read. Thanks!

I just purchased the same one from Rick a few days ago. Once I receive it I will post a review also. I'm currently lacking a Power Meter, but I will complete a few burning tests.
