My first real post, and I went big. I finally got around to putting together a few of the pieces I've acquired recently. Specifically, combining the amazing heat sinking power of a copper heat-sinked 2D Maglite build kit from Jayrob and a NDG7475 module from DTR. The price tag hurt, but upon seeing the beam all doubt was removed from my mind. It is simply stunning in person, and not too bad looking in pictures. It needs no long exposure or editing to see. Before I get around to a little review of the parts, let's take a look at some pictures!

To start off, this is by far the brightest laser I've ever gotten the chance to see. The beam is visible in a well lit room and outdoors. Indoors, it lights up the walls with a strong green.






Defocused a bit:






At night, it really shines (pun very intended)







Here it is on a night with low clouds. I couldn't tell if it was actually visible on the clouds, but it sure looks like it!



On the left is my 200mw PLP520-B1. Seeing them side by side convinces me it was worth upgrading to a higher power of a wavelength I already had.



And here it is next to my 1.8W 462nm and the 200mw 520nm



Here's the 520nm as compared to some of the others I have. Its color is clearly different when compared to a 532, but a little hard to tell the difference unless you have them side by side. These were taken by shining off of one whiteboard to diffuse the light, onto another whiteboard. I adjusted my camera to be as close to the color I see in the beams as possible.




Now, on to the laser itself. It is about the length of two C6s



The heatsink is a heafty 270g of copper, allowing for about 2 minutes on before cooling.





Here's the whole setup




The build quality from Jayrob is great. The only defect I saw was a trivial scratch on the face of the heatsink. Not a bother at all and only visible if you're looking for it. With the 32650s I have in it, I had to trim the spring a little so the endcap would close all the way, but this was probably my fault for using protected cells without his tailcap mod. Installation of one of DTR's 12mm modules was as simple as soldering a couple wires and sliding it in to the heatsink. The bore of the heatsink was precise enough I am not even using the set screw to hold it in.

As for service, he answered all of my questions quickly. The build took about 3-4 weeks from payment to receipt, but I imagine this varies depending on his workload. Overall, a great kit. As for DTR, he was awesome as usual. Some of the best customer service I've ever received is from the many diodes I've bought from him. Shipping was so fast I wouldn't be surprised if he drove it hundreds of miles to my house himself. You really need not look anywhere else for your diode needs. I'll look to both Jayrob and DTR for future builds of mine.

Damn geena!! Looks great. I got a death mace host im saving for my 1watt 520 build. Makes me want it built even more. So you got a complete driver and diode module? Im getting just the bare diode. I like soldering diodes for some reason!!

1w 520 is by far my favorite handheld I own. Bright as all hell and glorious. Great build and great photos.

I considered getting the driver separately and thermal epoxying it to the back of the heatsink. There's plenty of room back there, but I elected to have DTR put it directly on the diode. I then slipped a little cylindrical magnet between the driver and the wall of the module to help transfer the heat out. Without it, the driver cuts itself out after a minute and a half, with the heat sink barely getting warm. That seemed like a waste of good copper, and now I get about 2 minutes from a cold start before I don't feel comfortable letting it heat up anymore. Set at 2.4A and bucking from 8.4v, the driver puts out almost as much heat as the diode itself!

Great! Nice job, I'm headed that way myself but will be using a large expanded output.
