    I really like this light
    4 Stars
    I really like this light
    edit: added the images for a fix so the scope and light sit square as well as an image for the distance between the light and the amscope mount. Also just noticed that they no longer ship to my area? How odd.I really like this light, it is has a smooth variable adjustment and gets quite bright, however, there are two things that it could stand to have improvement on. The first being the lack of metal inserts for adjustment. This should not be a problem however as once you install it, it should never have to be moved. The second issue is that the power cord, which is a 12 volt wall wart has a plug that is too long to allow you to install the unit square with the scope. I fixed this with the use of a small "extension cable" that has a 90 degree angle one one end and a straight connector on the female end. The plug is a 5.5 O.D. and a 2.1 I.D. pin. I made the extension with a couple connectors that I had on hand as amazon for some reason feels that these connectors "require special handling and cannot be shipped to Alaska" (you get used to just making things yourself up here as a result), but you could easily find such a cable here on amazon when you order this light. After installing the 90 degree short extension, I am able to place the light square with the microscope frame and the entire feel changed as now I have access to BOTH the power switch and the adjustment without having to reach up under the microscope in an awkward fashion. If the plastic does eventually strip out, I might just grab a couple T-nuts from the hardware store and fit them on the inside of the light so when installed they push out on the ring securing it. . Hope this helps someone :)
