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

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!

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.

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

Works great! I am using a DSLR camera attached to the third ocular of my scope to create phone repair micro soldering videos. For this process you need exceptional lighting that is evenly distributed. A ring of LEDs is a great solution and the dimmer adjustment on this one makes it easy to get the right amount of light. Just remember to unplug it before you move your scope. Inexpensive and easy to install.

Designed for inspection style microscopes Works as advertised with dimmer

The scope I bought didn’t include a light, decided to go with this one after getting frustrated trying to figure out which one fit and what the differences were. It’s good enough. I don’t find it to be poor quality and I don’t see how you’ll strip the screws on it as others have complained about, maybe they’ve updated the design. Anyway it’s plenty good enough for my needs. Only complaint I’ve got is it should have been included with the $600 scope to begin with, they can’t have more $10 in this thing. I get they are in business to make money and are trying to hide the true bottom line price of the scopes, but it just leaves a less than perfect impression of the company. At least I knew up front I’d need this so both arrived at the same time, if I didn’t and had to go and immediately order something for my new scope to actually use it I’d be a little mad about it.

LLEGO BIEN

I purchased this for my AmScope SE400 microscope. This scope has a large working distance of about 8" and therefore requires a bright light to illuminate at such a distance. I have mounted it to the rectangular lens simply by friction fit (I just pushed it on until it stayed, no screws required). This light is great at eliminating shadows as I use it for micro soldering, but I still rely on the original gooseneck light for extra light. I use the 10x lens most of the time. I don't think this thing would illuminate enough by itself for magnifications higher than this. I figured for half the cost of the name brand light, I would give it a try. It appears that the LEDs are angled to focus on a single point about 2" from the lamp, so it very likely would work fine for a standard scope not meant to be worked under. Seems well made for Chinese quality, but I haven't torn it apart to check out the inside. I believe I'm going to repurpose it for a gig-pan macrophotography rig I'm building. It should work great for that.

Aro de luz con 144 leds va ajustado bajo la lente en un surco preparado para esto. Tiene una rueda para subir mas o menos la intensidad de la luz. Se conecta por enchufe q trae adaptador para enchufe europeo o el normal nuestro, vamos

Prodotto eccellente, molto luminoso. A questo prezzo 5 stelle! Ci sono illuminatori di altre marche, anche prestigiose, che si fanno pagare 5 volte tanto e valgono meno della metà. Unica pecca arriva con alimentatore con spina inglese (ma viene fornito adattatore europeo). A voler essere precisi, il connettore a barilotto dovrebbe essere angolato altrimenti non riesce a stare sotto alla testa del microscopio e l'alimentatore non è marchiato CE.

Excellent transaction just what I needed and great Quality

Bought to use on a Wild M5 stereomicroscope to save electricity. This microscope has a tapered nose piece but the 64mm diameter ring went on in a suitable place and easy to secure using the the three mounting screws. I couldn't locate it in the orientation I wished to because the on/off switch was fouled by the microscope stand. However, putting it on the right side of the stand it works fine - just a bit more fiddly for a left-hander! Came with a fitting for standard 42mm parallel sided nose piece 'scopes. Good bright adjustable light. A cool light compared with the usual Schott swan-neck light source but that's not a problem for me. I still use the Schott for high power work and the two together work really well for this. Of the three images - first has the spot light effect of the Schott system, the second the AmScope LED and the third both. So far very pleased with it and hope it lasts.

Passt super an unser Amscope sm-4tp Stereomikroskop. Beim Licht dabei ist alles benötigte befestigungszubehör sowie ein steckernetzteil. Das Licht ist schön hell und lässt sich stufenlos mit einem knöpfchen regeln. Außerdem gibt es einen einein Ein/Ausschalter
