Coast HP3R Penlight


Coast announced a new rechargeable flashlight that is small enough to carry pretty much everywhere. The HP3R Penlight is approximately 5.8” long and weighs less than two ounces. It charges through a USB port.

Coast made the HP3R to also take AAA batteries. The power output is less, but should you rely on the flashlight for a long period of time, a pair of alkalines can extend the run time.


On the lithium polymer rechargeable battery, the light is rated at 245 lumens with a 1.5 hour run time per ANSI specs. With a pair of alkaline AAA batteries, output drops to 86 lumens with a 2 hour run time rating.

Both battery types are included with the flashlight.

    I use a $10 Nebo “CSI” light that uses a single AA battery and is about 90 lumens. Its been very reliable as my EDC light for the past 10 years.

    Its a lot more compact than the one in this article.

      Well, you have a single-cell light, this is a two-cell light, it’s not entirely fair to compare them. I have a few lights, and my experience has been that the extra length of a a 2-cell light is a non issue when carried vertically, clipped to the corner of a pants pocket. I’m much more sensitive to the bulk of the diameter of the light for that kind of carry. I also have a far, stubby 1-cell CR123a light that carries well on the bottom of my pocket, but feels awkward on a clip.

      Anyway, I love my 2-cell AAA Preon, it’s about the size of a standard Sharpie marker, so it’s not exactly bully.

        I carry my light in my watch pocket in tandem with an extra mag for my Ruger LCP. They lock together nicely, and its a super compact package.

        The light is 3/4″ diameter, and typical in length for a single AA light.

        To each their own, was just sharing what i use.

    I use a $10 Solarforce light I got off Amazon with an 18650. It’s not as compact as this light, but it puts out a lot more energy and has more options. Also, lasts a lot longer.

    Small is good and all- but it’s like iphones or ipads- at some point the damn thing is too small, and gets damaged or lost easily. I have pockets and an EDC pack for a reason.

    I have a few Streamlight 66318 that is nice and bright yet does not chew up batteries.
    I EDC it and barely notice it is there.

    These days, I don’t look for a manufacturer, I look for a CREE emitter. If it’s got that, I’m good.

    Case in point: I just bought a Darkvim (who the hell is that? I have no idea) that runs off a single aaa battery and may actually live up to it’s lumen claim.

  • Cymond

    The MSRP is $95 and here’s a link to the actual manufacturer’s product page, since TFB doesn’t seem to post that sort of info much any more.

    • Cleophus

      Yeah, why is that? One of the first thing’s I want to know about a new product is HOW MUCH DOES IT COST??? Why is that so hard for writers to get right?

    The majority of the single LED Coast lights are using Cree emitters. My EDC the Coast HX5, personally. It comes with a regular alkaline AA, but actually supports rechargeable Li-Poly 18650 cells that bump the output from 130 to 345 lumens. I think it was something like 20 bucks, plus another 5-10 for the 18650.

    wake me up when some beats the Preon 2

    • Steve

      “Beats” in what way? The Preon 2 is non-rechargeable and doesn’t have adjustable focus…

      4sevens has been hit-or-miss for me. I really like some of their lights, and others I’ve wondered what they were thinking…

      I’ve picked up the following (can you tell I like CR123 lights?):

      Mini ML-X – not a fan of twist on-off, but otherwise a decent performer
      Quark Pro QP2L-X with Burst Mode – the tactical model has a better UI
      Quark Tactical QT2L-X with Burst Mode – best CR123 light they make
      Maelstrom Regen MMR-X – cool idea, good output, terrible UI in practice
