AmScopeLED-144W-ZK White Adjustable 144 LED Ring Light Illuminator for Stereo Microscope & Camera

Easy to install and quite bright when set to the high intensity.

I originally got one of these for my nice AM scope to help with my watch repair hobby and I ordered a video scope and ordered another one for it. They wotgreat and a worth every penny.

I like this light ring for my amscope Sm-4b. It works very well. The brightest is well bright enough! The variable brightness knob is very useful,and helps to get the best view on your project,depending on how much light you need.One thing people don’t really seem to mention,is that at a longer working distance(like with the 0.5x Barlow lens),the quality of optics is greatly deteriorated. The lights from the ring are angled and designed perfectly for the 4 inch working distance the Sm scopes provide. But when you go to 8 inches,the angled lights shine DIRECTLY onto what you’re looking at,from all directions,and this causes gray distorted colors. When you hold the light ring in your hand,you could see this. Have it aligned with the head of the scope,and move it closer to your object(for me it’s a circuit board I solder on) ,and you see it gets colorful and clear,since the lights shine around what you’re looking at. But when you move it farther away,the angled lights have more time and distance to cross over and shine across each other and directly onto what you’re viewing. This causes the gray and reflective distortion. A gooseneck may be best in this case,or somehow attach the light ring to “hang down” from the scope so that it is 4 inches from the object of view.I only mention the above to help anyone that gets the ring and is confused about optics being grayed. I saw a review on here about that. They probably used a Barlow lens. Perhaps the 0.7x wouldn’t be as bad since it’s a 6.4 inch working distance.Otherwise,this light ring is very useful. For the price,I can’t argue!

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 :)

Much better than the 80 LED ring from AmScope, and much cheaper. Some complained about the ring being made from plastic, and yes it feels cheap, but then it is cheap. The screws that tighten it to your scope go onto the black ring you see in the picture. That ring must fit your scope, or you will have trouble getting this LED light ring to hold one. The screws can't be tightened very much, because you will break the plastic that they are threaded into. That black ring has a groove cut out around the edge, so you only have to tighten the ring so the screws are in the grooves, they don't need to be very tight to hold on. So it might be the people who could not use the ring, or did not try to use the ring that had the most trouble with this light ring. The 80 LEd ring from AMScope put lines in my picture from the camera. The sad thing is that their tech support could not help me get rid of the lines, so the ring was defective, and i needed to return it. AMscope made me pay to return it, it cost me $15 to ship it back. It was heavy because of the metal control box. AMScope has some pretty shady business practices, so beware as you shop. Returning defective products should never cost the customer money to return. At AMScope, you will pay to return any defective products.

A very effective, well made, reasonably priced accessory for stereo-optic microscopes.Stereo scopes are commonly used for viewing opaque objects: rocks; coins; macroscopic dissections; watch innards, etc. Consequently the stage is usually lit from above. I have an AmScope stereo 'scope that is has lights both above and below the stage -- unfortunately, with certain objectives the upper light is actually partially blocked by the objective. The fix for that is either an expensive external light mounted off the one side, or a ringlight.This ringlight uses LEDs, which is a nice complement to the halogen lights that came with my 'scope. It mounts easily above the objectives, and distributes light evenly over the stage. The intensity is adjustable from nearly full-off to full-on, via a small rotary control. If I were going to change one thing about this light, it would be to have it plug into the microscope base itself for power, rather than running a separate cable to yet another wall wart. Can't have everything, I guess. Otherwise, no issues.Once I installed this light, I find I use it almost all the time. Very useful, and recommended.
