I learned quite quickly that magnifying lamps are available from about $38 to about $400. First you are confronted with an alphabet soup of initials... KFM, LFM, IFM, LED, and ESD plus what seemed to be endless choices for mounts, length of reach, lights, position of lights and circles of increased magnification. etc...and then there's the shape of the lens and the quality of the lens itself. I was desperately wishing there were somewhere I could just try one... I had already ordered one that was mid-range price and sent it back as it had a problem with distortion and the lights were on each side of the lens which was terrible.
Shirlee Fassell published on post on this subject. She was having the same problems but her husband bought a lamp at All-Spec and she loved it... And that is how I came to order this..
And I can tell you right off the KFM refers to the quality of the construction. This lamp is heavy duty construction and suitable for use in a lab and when I position it, it stays there. The head is completely adjustable... side to side, up and down and tipped every which way. This is especially nice when I am working on MOP buttons which have weird reflective areas. I had a 3 diopter (strength of lens) and moved up to a 5 diopter and chose a LED lamp which is dimmable. The lens itself is optical quality and fabulous.. This model (click to find site) was about $340 plus shipping and I could not be happier. This is definitely a case of getting what you pay for. The next post will be a special edition of buttons done under the new lens.
