  • much better than sku.46390

    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

    OtherThoughts:

    After bad experience with sky.46390, I was pleasantly surprised - these modules are excellent value for money.

    Bottomline:

    If you're looking for small laser modules, these are the smallest ones of good quality at DX. Will order more.
