Dioptre strength and lens diameter trade against each other
A magnifier lamp puts a lens and a ring of light over a workbench, for soldering, painting miniatures or sorting small parts, and its two main figures pull against each other. Dioptre strength describes the lens power, and the magnification a maker prints beside it depends on a convention for the viewing distance — the diopter figure is the more comparable of the two. A stronger lens usually means a smaller lens diameter and a shorter working distance, so a lens powerful enough for surface-mount parts may leave too little room for an iron underneath. Lens material is glass or acrylic, and glass resists scratches from tools. Light output is published in lumens or lux at a distance where the maker is careful, and color temperature in kelvin decides whether wire colors and paint read true. The arm is described by its reach and its joints, and a spring arm that drifts down is the complaint that follows these lamps. Mounting is a desk clamp, a weighted base or a floor stand. Then dimming, a lens cover that stops sunlight focusing through the lens onto the bench, and whether the light head can be replaced. We compare diopter strength, lens diameter and material, light output and color temperature, arm reach, mounting and dimming.

The optical power of the lens, published by the manufacturer. It determines the magnification.
No: the diameter decides the visible field, the diopters decide the magnification. The two are published separately.
The lens material is published. It changes weight and resistance to scratching.
It is published together with light output. The choice depends on the work and on personal preference.
Published mounting says so: bench clamp, weighted base or rolling stand depending on the model.
Adjusting the amount of light. Its presence is published on every listing.
The distance reachable from the mounting point, published by the manufacturer.
That depends on the person. This site publishes optical and lighting specifications, with no usage advice.
Choose by working distance and light. Very high magnification claims on large lenses deserve doubt.
Four machines in five must publish the value before a column is raised. Below that, it would be comparing absences.
