Medical Penlight with Pupil Gauge

The Nitecore MT06MD-PG is a compact penlight built for clinical examinations. It uses a high-CRI Nichia 219B LED to render colours accurately at up to 180 lumens. A printed pupil gauge on the body allows quick neurological checks. The light defaults to a 4 lumen low mode to protect patient eyes.

For Clinicians Needing Accurate Colour

Doctors, nurses and EMTs benefit from the >90 CRI output and RG0 rating that eliminates blue-light hazards. The diffused beam suits pupil checks and wound assessment at close range. Buyers who need a high-intensity throw for distance work should look at a different tool. The 860 cd peak intensity is optimised for near tasks, not long-range illumination.

Nichia 219B LED with >90 CRI

The Nichia 219B emitter drives the clinical utility of this penlight. Its high colour fidelity reveals tissue detail and true colour during exams. The RG0 classification confirms no photobiological risk for eye assessments. Two AAA cells power the light for up to 35 hours of runtime.

Questions about this item

How do I install the 2 AAA batteries and avoid the common mistake with the tail switch?

Unscrew the tail cap, insert two AAA cells with the positive ends toward the head, then tighten the cap; the reverse-click switch activates only when pressed fully, so a partial press will not turn the light on.

What maintenance will the Nichia 219B LED and pupil gauge require over time?

The LED is rated for long life and needs no user service; wipe the printed pupil gauge on the housing with a soft cloth if it becomes dirty, and replace the two AAA cells when output drops below usable levels.

Which limit appears first during continuous medical use — heat, battery life, or output drop?

Battery life is the first limit; the light runs up to 35 hours on two AAA cells before output falls, while the 180 lumen high mode and 860 cd peak intensity stay stable within that period.
