NDG7475 1W 520nm

NDG7475 1W+ 520nm Green Laser Diode

Max Suggested Current 2.2A

For more info see testing at bottom of listing

These are real NDG7475 not the NDG700/NDG7575 which can be pushed to 1W and are a lot of times sold as the NDG7475 by many sellers. 

Real NDG7475 will reach 1W with 1.5A-1.6A as shown in the testing and when pushed they pull back a little over 1.4W. 

NDG700 sold as 1W NDG7475 requiring 1.7A-1.8A.

This diode with the G-2 has a pretty identical box reflection that the 9mm 445nm does.

So next I decided to put them head to head and @ 25 Feet they were both about 30mm with a G-2.
