10X LED Magnifying Lamp with Clamp, KIRKAS 2,200 Lumens Dimmable Super Bright Daylight Magnifying Glass with Light and Stand, Adjustable Swivel Arm Magnifier lamp for Reading Repair Crafts-White

The variable brightness on this thing is probably its best feature. The magnification is good as well depending on the task, just don’t expect to be able to do microbial work with it. The glass is large enough that you don’t have to get in super close to see everything or shut one eye. Being LED lights it’s plenty bright and it doesn’t get hot too the touch. The range is pretty decent and it’s fairly adjustable from almost any angle.There are two things that I disliked, but they’re both super easy fixes.First: Change the damn knob near the base of the lamp. It’s the smallest knob on the entire fixture so it’s difficult to turn and get a tight grip on if you want to set the lamp from swinging any. While you’re at it just replace the screw that comes attached to the knob as well. It’s just a regular machine screw with a flat bottom. I changed mine out with a half inch quarter 20 set screw (the screws that have the tapered pointed tip.) and a large tri-knob I had left over from a telescope dismount. You could also use any large knob with a regular quarter 20 screw attached and just file the tip down to a fine point.Second: the base is just a tube of aluminum so it’s hollow and not very rigid. This leads to the lamp base being easily bent if too much force is placed on the head during movement AND it doesn’t give the set screw a good surface to grip onto. My solution was to take a 2 inch long of solid 1/4 inch diameter aluminum rod to shove into that hollow section. It fit nicely after a little sanding and some epoxy to hold it in place. This increased its rigidity, as well as gave a solid surface for the set screw to bite into.

I had one of these and it finally fell apart. So, I bought this one. Wow! It is so much better than the old one I had (different brand). I can't believe I put up with the old one for so long. I definitely recommend this to anyone who does close up work and needs help seeing. The light is adjustable. You can make it dimmer or brighter, whatever works best for you. The magnifier is the best I've ever used. And I like the cover that goes over the magnifier. It keeps dust off of it when not in use. The clamp for the table is very nice. No plastic. You can adjust it as tight as you need it. I would buy it again.

I bought this to help with repairing/building electronic assemblies. It is lightweight and of good quality.Although the label states it requires 110V 50/60Hz, it does in fact work perfectly on a 220V supply ( there is a switched mode PSU built into the lamp housing).The clamp is perfect for my workbench (though it won't fit a second table I have with a beveled edge since the clamp is not deep enough to fit the flat section of that particular table). The maximum clamp opening is 56mm (minimum is 3mm) and the depth is 43mm (36mm to the edge of the rotating section). The clamp has a thumbscrew one can tighten to prevent the lamp from swiveling around.The central arm joint has a knob that can be used to tighten the joint and keep the lamp in position. When the lamp is lowed such that the angle between the arms is about 80 degrees or less, the knob hits the spring, so depending on the knob position the spring has to bend around the knob.The lower arm can lower almost horizontally across the desk, but can bend backwards only about 45 degrees.Another knob tightens a small clamp around the stem of the lamp housing itself to lock it in position. The housing can therefore tilt up and down or rotate on its stem, but it can't move sideways.Unfortunately the housing clamp knob needs to be turned really tight to hold the housing in a stable position and is not that sturdy. I am worried how it will stand up to being tightened so much. I am thinking of trying to install two split washers to help make it tighter.The lens is very clear glass with no tint. However the lens is advertised as being a 5 diopter lens (2.25X magnification or a focal length of 200mm), yet my measurements put the focal length at 333mm (i.e. a diopter of 3 or only 1.75X magnification!The lighting is very good, with a small rotary potentiometer with built-in switch for brightness control and to turn the lamp on/off.Overall I am very happy with the lamp but took off a star for incorrectly advertised magnification.
