## Description

LED Pen Light Rechargeable Flashlight Small EDC 330 Lumens Penlight for Inspection Repair Camping

Review: Light weight, and even beam center-to-edge - I was looking for something light-weight and easy to turn on/off for my wife - and this fits the bill perfectly. Bright, circular beam with even light across the entire beam.
Review: Nice penlight, would buy again. (includes comparison to the Nextorch Dr. K3) - 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. K3 Output: 4 lumens Runtime: 15h Weight: 38.5g Water resistance: IPX7 K3s: Output: 2 lumens Runtime: 55h Weight: 19.4g Water resistance: IPX4 For 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!)

### ⭐⭐⭐⭐ Too bright for eye exams
*by P***E on December 18, 2022*

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 bright I totally dig it’s little size and how it clips to my pocket and stays there for my entire shift I’m sure I can look around and find some filters to decrease the brightness or change the color
