    Default Review of $170.00 445nm Lvyi Electronics Laser

    I received my 1 Watt Laser on Sept 20/10

    Opening the Package

    The Laser arrived in a neat black "gift box" complete with charger and Safety Glasses
    and Everything was nicely wrapped up in bubble plastic.
    So no change of it getting damaged in transport

    Instruction Sheet

    A clear instruction sheet is provided with the laser.
    Showing how to insert the batteries
    A caution is also shown that inserting the batteries in the wrong way will damage the laser driver. So be warned

    The Host

    The host is a perfectly machined part.
    All the parts screw in correctly and there a no metal shavings on any of the screw threads
    Also the clicky switch feels solid and works perfectly every time.

    It seems the adjustable lens is installed from the inside of the front
    of the host and the focus knob is epoxied to the protruding lens
    housing. Then the Laser and Driver get screwed in from the rear of
    the front host section locking the Lens assembly in place.

    The lens and front window are not removable without unscrewing
    the LD/Driver assembly...

    There is a 6 months manufacturers guarantee on the laser so that should be ok

    The specified batteries fit loosely in the host... but do not rattle..
    The host inside diameter was 0.753" and the batteries outside diameter
    is 0.650"....

    Tested Specs

    The tests were done with my lm10 thermopile and multimeter.
    first test showed 898 mw

    Power Output ---------------------- 1042mW
    Beam Profile @ 30' ---------------- 19mm X 1.5mm

    WOW!, Nice unit you got there. I wish mine lived up to the specs that yours does. Mine only puts out 600mW on fresh batts. This is a nice laser (if you get one up to spec) The adjustable focus is nice and smooth.

    Nice job on your review and great photos too.

    TY for sharing.
    Can you give me any tips for getting the host of an Aries 75 apart. It seems that it has some sealant(locktite) in the threads or was put together so tight I cannot get it apart. I won it as a broken professional PGL on Ebay for 51.$ and would like to use it as a host for a 445nm diode.

    thank you for any advice

    not sure if this post is for me or the OP.

    and Yes, no goggles are needed for broken lasers...but they are for all that work.... IMO

    Nice review of that 445nm Laser...

    I bought one from the Same seller...
    My Laser outputs less than yours.. Here is a link
    to the Review I did on the same Laser...

    I did find a few negative things with it...
    and the Seller seems to have a problem with his
    communication/social skills..
