NEXTORCHProfesstional Medical LED Penlight Flashlight with a Clip Small Torch for Nursing Students Doctors AAA Battery K3S

I like the brightness of the light for pupil assessment. it does not flicker with movement.

small, reliable, durable

I have been using the Dr. K3 for almost 2 years, and really like it. WAY better than some of the cruddy penlights I've seen used around the hospital. So when I misplaced my Dr. K3 I figured I should get a backup. I saw that this model, Dr. K3s was (a) about half the price of Dr. K3 and (b) at the time of purchase, it had a 25% coupon. Seemed like a no brainer.Look and feel:The K3s is smaller (shorter by about 5/8"), and definitely feels less substantial. It is convenient that it has the pupil sizes on the side, as opposed to the original which had a ruler on the side (also functional, just the little circles are faster to compare).The click on both is good. It feels more substantive on the K3--sounds cheaper on the K3s, but it could be that I've been using my K3 for a long time. At least on this version of the K3s, the button is loose and will definitely rattle around a bit.Ultimately, the clip is what would prevent me from using the new model as my penlight. It will probably work just fine, but the clip on the original K3 is so nice that there's no comparison.I contacted Nextorch to get the technical differences.K3Output: 4 lumensRuntime: 15hWeight: 38.5gWater resistance: IPX7K3s:Output: 2 lumensRuntime: 55hWeight: 19.4gWater resistance: IPX4For me personally, I will continue to use the Dr. K3, but recognize that I am very particular about what lives in my scrub pocket. Minor details make a difference for me, and I would pay the extra for the nicer clip. (But it's nice to have a backup!)

Bright is great for everything but I don’t like making people squirm when I check for PERRLA. I guess you don’t have to shine it directly into their eyeballs but I really wish it wasn’t so brightI totally dig it’s little size and how it clips to my pocket and stays there for my entire shiftI’m sure I can look around and find some filters to decrease the brightness or change the color

time will tell how durable it is but it has withstand 1 month of use which includes many sanitations during shifts

Small compact and durable. I use this for rapid triage screenings. I’m getting older now and brighter light is a must. This is ok. The light casts a perfect circle of illumination on a posterior pharynx, and nothing more. So if exudate is beyond the “event horizon” you just can’t see it. No problem...just love the light. The light isn’t as bright as a light from my otoscope. It works just fine but I want a brighter light for my eyes. Will likely find another light until I get the real deal.

I have used many cheaper pen lights in nursing and really havent been WOWd. What could you expect from a penlight? I saw the Welch Alyn one for a funny amount of money and the bulbs apparently easily broke... this one, however, is solid. The price is just right, feels like good quality, uses AAA battery x1, not some random penny batteries, the light output isnt damaging, and the light border is defined and clear. Perfect tool to assess pupils and oral cavity. Love it

Packaging is excellent, big outer box, plastic encasing with a seat for the penlight. Battery is included and inside the penlight with plastic isolator. The penlight gives proper even lightspot, it did not hurt my eye, so a patient should be ok with it as well. The pupil size marker is there, however the numbers in mm are in tiny fonts, and might be difficult to read at a bedside, unless you memorized them.I am very pleased with the purchase and planning to get few more for my colleagues.
