Listing is for a single 1.2W 520nm NDG7475 laser module. Unit is mounted in a 12mmX30mm high quality copper module for max cooling and stability. It is prewired with a 2.2A SXD buck laser driver and comes with the new DTR-G-8 glass lens. Unit measures 12mmx30mm fit for standard 12mm laser heatsinks. The unit is ready to be dropped into your final project. No setting current or soldering diode to driver. Just place in heatsink and connect leads to your power supply.

Input voltage range is 6V-9V. Great for use with two Li-Ion's in series. Suggest two 16340/18350/18650 3.7V Li-Ion's. You can also use a 6-9V 2A wall adapter or bench power supply.

Warning. There are many reports on the forms and I have had multiple customers informing me they have received 700mW NDG700 520 diodes from foreign sellers here on ebay advertised as the real NDG7475 and told to over drive the diode past safe limits to get 1W out of it. Also listed as NDG7575, NDG7K75, 1W 520nm NDG7475(T) or just 1W 520 diode. This may make it an accurate claim of potential power but is deceptive and will reduce the life of the diode significantly. The actual NDG7475 1W 520nm diode will hit 1W @ 1.5A where the NDG700 needs 1.7A.

Here is what you get. The X-Drive is encased in the back of the model connected to the diode.

Modules are wired with extremely flexible 26AWG wire that is burn proof and makes for very easy soldering.

Wire assignment is:

Driver Output Current 2200mA

Driver Current Draw 1.7A +/- 0.5A

Power Output 1.2W-1.4W

Driver Type Constant Current

Lens M9x0.5mm Threaded DTR-G-8 Glass Lens

Here is my testing on this diode

Nichia NDG7475 1W 520nm Laser Diode
Exciting day. Finally got my 1W Green diodes and could not wait to do some testing on them.:eg:

This 9mm diode has off center pins.

First thing I did is pop one in a sink and fire it up. Was amazed the brightness of the beam indoors during the day. Really bright.

Then beam specs and divergence seem to be nearly the exact same as the NDB7875 and M140 445nm diodes.

This diode with the G-2 has a pretty identical box reflection as the NDB7875 and M140 as well.

So next I decided to put the NDG7475 head to head with the NDB7875 @ 25 Feet they were both about 23mm with a G-2.

So now on to the meat here is the LPM test of the diode. I expected this thing to dim maybe around 2.5A but it just kept going. I decided to end it when I started getting foldback around 3.5A. There really was not much gain from 2.5A up but wanted to see where it dimmed but it never did at least to where I felt it would not blow up as they are kind of pricey.:whistle:

Would not suggest driving past this point. Stay 2.4A or under.

There you have it. Whole lot of of Green goodness. Oh and for some dark shots.
