(includes comparison to the Nextorch Dr. K3) *by on Reviewed in the United States 9 January 2019* 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!) ### ⭐⭐⭐⭐⭐ Super durable - best pen light ever! *by on Reviewed in the United Kingdom 13 November 2023* I accidentally washed this NEXTORCH pen light with my uniform, the battery was dead, so I changed the battery and this NEXTORCH pen light turned back on imminently, as if nothing had happend. Working just as well now as it did a year ago, even after having it went through the wash.Incredibly impressed - the price definitely is justified by how durable the torch is ⭐️⭐️⭐️⭐️⭐️ ## Frequently Bought Together - NEXTORCH Professtional Medical LED Penlight Flashlight with a Clip Small Torch for Nursing Students Doctors AAA Battery K3S - MEUUT 2 Pack Medical Scissors Trauma Shears -8 inch Patented Bandage Scissor Heavy Duty Surgical Grade EMT Scissors for EMT Workers Doctors Nurses - 3M Littmann Classic III Monitoring Stethoscope, 5806, More Than 2X as Loud, Weighs Less, Stainless Steel Rainbow-Finish Chestpiece, 27' Raspberry Tube, Brass Stem and Headset --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/590234979-nextorch-medical-led-pen-light-with-pupil-gauge-for-doctor](https://www.desertcart.jp/products/590234979-nextorch-medical-led-pen-light-with-pupil-gauge-for-doctor) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-23*
