## Overview

The AmScope LED-144A is a professional-grade 144-LED ring light designed for stereo microscopes, featuring four independently controlled lighting zones for customizable, shadow-free illumination. Its cool LED output protects sensitive specimens, while the universal adapter and auto-detecting 110V-240V power supply ensure broad compatibility and ease of use. With a 100,000-hour lifespan and rheostat dimming, it’s engineered for long-term, precise microscopy work across scientific, educational, and industrial applications.

## Description

The AmScope LED-144A stereo microscope illumination system has a 144-bulb LED ring light with four separate zones to independently control light intensity and direction. The ring light provides bright, cool light for working with temperature-sensitive or live specimens, and shadow-free illumination. A rheostat controls the amount of light emanating from the lamp. Power and adjustment controls are located on a control box to speed adjustments. The ring has a 2-1/2" (64mm) inside diameter and a 4" (100mm) outside diameter. The light includes an adapter ring for mounting on a stereo microscope head. It has a 100,000-hour life span and a 110V-240V auto-detecting power supply. Microscopes are instruments used to enhance the resolution of an object or image. Types include compound, stereo, or digital. Compound microscopes use a compound optical system with an objective lens and an eyepiece. Stereo microscopes show object depth in a three-dimensional image. Digital microscopes are used to display an image on a monitor, rather than looking through a lens. Microscopes can have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying magnification abilities. Magnification ability refers to the size of an image. Resolution, also known as resolvant power, refers to the clarity of the image. The interaction between field of view (FOV), numerical aperture (NA), and working distance (WD) determines resolution. Microscopes can control magnification through a fixed focus, or through a range of adjustments. They can also utilize LED, fluorescent, and mirror light sources to help control viewing capabilities. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries.United Scope manufactures microscopy equipment and accessories under the brand name AmScope. The company, founded in 1996, is headquartered in Irvine, CA.What's in the Box?LED Ring lightControl boxMounting ringPower cord

Review: Very good light ring for low distance work. - 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!
Review: A must have for mid-range AmScope stereo-optic microscopes. - 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.

### ⭐⭐⭐⭐⭐ GREAT ILLUMINATION.. Supergood Price..!
*by D***E on March 25, 2025*

You can't beat this for the price..! Adapter ring. incorrect to thread into my microscope, so I attached ring to scope with Gorilla Super Glue. Rock solid in seconds...! ( I mention this because not all plastics work with all adhesives, but this held securely for months now with recommended product....order a tube in case you have the same situation with your Bausch & Lomb stereo microscope.)
