Steamlight ProTac 1L

Let me start off with the answer you seek: Go purchase this light now!  Seriously; follow this link and order this light now.  You have two battery choices, AA or CR123, you can’t go wrong with either.

When I reviewed Nitecore SRT3 back in February I made mention that I had replaced it with a Streamlight ProTac.  That replacement took place in early January so I give you a short-term review.  Short term in this case means about 3 ½ months of daily carry and use.


The ProTac 1L is a well-made, decent sized (as in not too bulky, but big enough to provide decent light) LED flashlight made by those purveyors of affordable lumens, Streamlight.  This is the 4th Streamlight flashlight I have purchased, and once again I am impressed.  In fact, I hope I have finally realized that Streamlight should be my go to manufacturer for flashlights.  Sure, Surefire is great, but on a cost vs. benefits scale, Streamlight holds the key – at least for me.

Here is what Streamlight says about their little flashlight and the published specs:

An ultra-compact tactical light, the ProTac® 1L is small and easy to carry, and uses a single lithium battery. The light is one of the most versatile personal carry lights available for users, from law enforcement personnel to industrial technicians.

Did you note the part I underlined above?  Did you notice the photos?  Industrial technicians; yup, that is the category I fall into.  I buy small  flashlights with two goals: 1) personal use, be it protection or finding the crayon my son dropped at the restaurant and, 2) ensuring airworthiness of aircraft at my day job.

I am not a LEO.  I am not a fire-fighter.  I am neither a major nor minor league door kicker.  I research and review my non-firearm related EDC gear with realistic EVERYDAY goals in mind.  I am way more likely to drop my flashlight from a ladder into a bucket of waste jet fuel (the ProTac experienced this once) than to survey a smoke-filled room for survivors, or bad guys.

So, after daily carry I can give the Streamlight ProTac 1L a solid 100% review.  I have dropped it from my pocket, kicked it, dropped it into the previously mentioned bucket of jet fuel, sprayed it down with isopropyl alcohol (to remove the jet fuel), and it even got put through the washing machine once.  It has proven itself tough.

Like Krylon of flashlight world; no drips, no runs, no errors.  That said, I can, and will, do an abbreviated Pro’s/Con’s for it.


Dependable – if a flashlight isn’t dependable, why bother.  Buy this with confidence.

Bright – It is not retina searing, but it is bright enough for every day task.  I would recommend something brighter for a bump in the night though.

Size vs Power – about perfect.  It is comfortable and lightweight.

Selectable Modes – I don’t need the strobe or the low power mode, but thankfully Streamlight gives us the option to turn them off permanently.  Bright is what I want, bright is what I get.  Circuit engineering done right.


My only complaint is with the clip.  It is stout and hasn’t lost tension, but the allowable positions leave more of the flashlight sticking out of my pocket then I would prefer.  I know; first world problems.

As I said at the beginning, go buy this light.  I have two co-workers with the 2L version, which adds a second battery.  They are equally worthy of your ownership, although I find them a little long for everyday carry.

So you are still on the fence as to whether you should purchase the Streamlight ProTac 1L or not?  I’ll let Arnie opine.




  1. I think my 2L is a great light. I bought one for my wife to carry in her purse. Not long after, I wished I had one also. When they came on sale again, I got one and carry it every day. If the 1L is anywhere as good, it is a great light

  2. My 2L just went to the big flashlight graveyard in the sky. I train for trail running at night and it has been a constant companion for 6 months. I contacted Streamlight and am sending it in for a warranty repair. Great customer service. Hope to have it back soon. Might go ahead and purchase the 1L for the next couple of weeks.

  3. I have a protac 2aa. I agree that streamlight makes great lights. For a single CR123 I went for the “all the lumens” approach and bought a Fenix PD22UE. I can’t complain much. 500 lumens, 1 CR123. The clip is useless but I have a kydex pouch.

  4. I love streamlight, they are pretty much my go to for personal gear. I’ve carried a protac1l for daily carry for a little over 2 yeas now and it’s been the best carry light I’ve had.
