    much better than sku.46390

    posted by linoleo on 03/25/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:
    - more solidly built than sku.46390 - much brighter than sku.46390 - appears to have constant current driver: two transistors are visible on the PCB, and my samples pull a constant ~20mA from 2.5V to 5V
    Cons:
    - larger diameter than sku.46390 - no adjustable focus (but well focused as is) - spot is elongated

    2~5mW Dot Red Laser Module (5-Pack/3V)

    posted by dagabu on 04/04/2011 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:
    Upon un-packaging I noticed that the all brass construction of the laser head was well milled and bright. It was a pleasant surprise to see that since that means that I can solder plates, tubes, mounting arms etc to them without difficulty. I then hooked...
    Cons:
    There are no cone to report, the build was nice and the soldering looks nice as well.
