Unitron 15856 LED Ringlight 60LEDs,61MM I. D. w/Dimmer control A/C 90-265
Unitron 15856 — LED Ringlight, 60 LEDs, 61mm ID, Variable Dimmer, AC 90–265V
The Unitron 15856 is a 60-LED ring illuminator designed for stereo microscopes, inspection systems, and precision assembly workstations. With a 61mm inner diameter, it fits directly onto standard stereo microscope objective nose pieces and third-party ring light adapters. The built-in variable dimmer provides stepless intensity control, allowing operators to tune illumination for surface inspection, soldering, assembly verification, and PCB rework without glare or shadow. Universal AC input (90–265V, 50/60Hz) makes it compatible with both US and international power systems.

Key Features
- 60-LED array — even, shadow-free illumination across the full field of view for inspection and precision work
- Variable dimmer control — stepless intensity adjustment to optimize lighting for surface finish inspection, solder joint verification, and assembly tasks
- 61mm inner diameter — fits standard stereo microscope objective noses and ring light adapters
- Universal AC input (90–265V) — compatible with US (120V) and international (220–240V) power without a converter
- 10,000-hour LED life — long-life LEDs minimize maintenance and replacement costs vs. fluorescent or halogen ring lights
- Low heat output — LED construction runs cool, reducing operator fatigue and preventing heat-sensitive samples from being affected by the illuminator
Frequently Asked Questions
What microscopes is the Unitron 15856 compatible with?
The Unitron 15856 has a 61mm inner diameter and is designed for use with Unitron stereo microscopes. It is also compatible with other stereo microscopes and inspection systems that accept a 61mm ring light. Verify your microscope’s ring light adapter inner diameter before ordering. Contact MTE Solutions to confirm compatibility with your specific microscope model.
Does the Unitron 15856 work on 120V US power and 220V international power?
Yes — the 15856 accepts AC 90–265V at 50/60Hz, making it compatible with standard US 120V outlets and international 220–240V power without requiring a voltage converter or separate power supply.
How does LED ring light illumination compare to fluorescent or halogen ring lights for inspection?
LED ring lights offer several advantages over fluorescent and halogen alternatives: significantly longer lamp life (10,000+ hours vs. 1,000–2,000 hours for halogen), lower heat output that won’t affect heat-sensitive components or assemblies, instant-on with no warm-up period, and consistent color temperature over the life of the unit. The variable dimmer on the 15856 also provides finer intensity control than most fluorescent ring lights.
Can the Unitron 15856 be used for PCB inspection and solder joint verification?
Yes — the 60-LED even illumination and variable dimmer make the 15856 well suited for PCB inspection, solder joint verification, component placement checks, and rework operations under a stereo microscope. The ability to reduce intensity helps reveal surface texture on solder joints and reduce glare from reflective PCB surfaces or component leads.
