1. Streamlight TLR-1 HL – Best Overall Flashlight

It won’t be wrong to say that Streamlight has a monopoly when it comes to tactical and firearm-related lights and LEDs. In the same product line, we have TLR-1 that does not only have a potential output of 1000 lumens (lighting up a greater area) but also possesses 20000 candelas of beam intensity, which is the main factor in quantifying the performance of light, especially one mounted on a weapon.

One thing that makes it the best in its league is the balanced beam pattern. When you turn it on, you can see a central hot spot since the brighter core beam, and then it fades out around the edges and has a wide spill that increases the field of view and allows you to spot anything in the surroundings without losing focus at the main target.

Also, it provides you with 1.5 hours of run time on battery. And comes with a great setting for installing batteries with an easy click and tethered switch, so you don’t end up losing the battery door. Cool, isn’t it!

Personal Experience

I used to own the previous version of TLR with 800 lumens and 12000 candelas. Now that I had bought this upgraded version, I wanted to try them out side by side to see the difference, and I wasn’t disappointed. I tried it at a distance of 30 yards in my backyard and then at approx. 110 yards at the other side of the lake, and the performance was impeccable. Bright, intense, and widespread at the edges. Perfect! The new TLR-1 with 1000 lumens could be differentiated from the 800 one on the account of light intensity, though.

Reason To Buy

If you desire a light that’ll match the elegance of your Fn 509 tactical and would also be efficient and brilliant in performance, then Streamlight TLR-1 is the product for you.

  • Ambidextrous switch
  • Easy mounting
  • Heat safety
  • Complete package
  • Less concentrated beam has a relatively lesser beam concentration, but it doesn’t fail to be bright enough for tactical situations.

2. Streamlight TLR-7A Flex – Best Light for Carriage

Streamlight’s TLR HL series is already a hit. The Flex series differ from the one discussed earlier on the accounts of low-profile and mounting options. TLR 7A Flex’s compact design makes it easy to mount and handle. And who doesn’t love an accessory that doesn’t take up much space. You’d adore this if you use it on duty and have to carry the weapon with you most of the time since it was predominately designed for pistols, and that’s where it excels.

Another amazing feature that makes it a fan favorite is that it gives the user to choose the mounting type according to his shooting style. If you prefer a higher grip style, put the high mount on, or if you are a fan of a low mount that prevents snagging, I must add, then you can just switch it up without inconvenience.

A light that’s compact, easy on hands, and bright, it’s a grab!

Personal experience

I tested it out in my backyard, starting from aiming at 50 meters and going up to 150 meters. It had a great intensity and peripheral spill, much like its fellow TLR HL. Also, I loved the two mounting options and ambidextrous switch feature because my left-handed friend, a fan of the high mounting style, could join me.

Reason To Buy

A Streamlight light, with most of the features same as the one with a higher price – TLR- 7A Flex gives you a great value for money and is the best pick for its compact design and excellent performance.

  • Safe-off feature
  • Durability
  • Good Battery life
  • Waterproof
  • No heat prevention – it doesn’t offer a heat sink to prevent overheating. Guess you’ll have to look out for it yourself.

3. Olight PL-Mini 2 Valkyrie – Best flashLight For Home Defense

Olight PL-mini 2 Valkyrie’s compact design and rechargeable battery features make it the best choice for self-defense and tactical situations.

It stands out in the crowd of other lights because it has a built-in battery that requires charging only, unlike its fellow lights that use CR123 batteries. The USB connector comes with it that has a magnetic metal ring on one end that connects to the light and charges it, that too without removing it from the pistol. This is a perfect light for you if you don’t want to stock up the batteries or avoid the fatigue of changing them every once in a while. You just charge it once and enjoy up to 1 hour of shooting time.

Another feature that makes it a dream light for any gun enthusiast is its compact, low-profile, snag-free design. It’s extremely lightweight and doesn’t take up much space on the pistol. This feature makes it perfect for home defense because it’s easy to carry and easy on the hand.

Personal experience

I tested it in my hallway, aiming at the door 12 feet away, and it had a great central spot and the peripheral lights lighting up the whole hallway. Also, there was no loosening of the mount due to recoil even after 100 rounds, and as mentioned above, the weight was negligible. I’d recommend it!

Reason To Buy

Go get yourself Olight PL- mini 2 Valkyrie if you want a mini but mighty light for your Fn 509 tactical.

  • Quick and safe attachment
  • Extremely durable and reliable
  • Budget-friendly – it’s really worth the bucks. It’s cheaper than many other lights with the same or lesser features than it offers.
  • Drop-in lumens can be a concern for some people since it has a run time of 1 minute at 600 minutes, and it will decrease to 60 lumens in an hour.

4. STREAMLIGHT TLR-7 – Best Weapon Light For Beginners

Here we are with another light from Streamlight yet again. Though similar in name and most features, Streamlight TLR-7 differs from TLR-7A in terms of money. It’s a perfect option for someone looking for an efficient light that isn’t heavy on his pocket.

The TLR-7 is one of the best tactical lights for the Fn 509 tactical because it’s small, lightweight, and packs a powerful punch. It’s a great light for beginners because of its size and weight. It’s easy to carry and doesn’t weigh down your pistol.

It offers a highly concentrated central spot and great spill, providing maximum situational awareness, and easily lasts for 1 and a half hours.

It possesses an ambidextrous switch with a constant-on and momentary-on mode. Moreover, it is an IPX-7 water poof and has an aluminum housing and a black anodized finish.

Reason To Buy

You can get what’s needed in a good light staying within your budget.

  • Ambidextrous switch
  • Durable
  • Budget alternative
  • It’s certainly heavier than other lights

5. SureFire X300 Ultra X300U-B – Most versatile Light

As the name suggests, SureFire X300 Ultra is one of the most versatile tactical lights for Fn 509 Tactical.

It’s definitely an expensive one, but it has a lot of great features, and primarily it is concentrated and intense light, on the accounts of 11,300 candelas. It has a super bright central spot that might also hamper the adversary’s vision, a tactical advantage there. It also has excellent spills around the edges and would brighten up a room if so.

It has DG and XT remote switches that are pressure-activated optionally and provide controlled precision without changing your grip on the weapon.

If mounted on an extremely lightweight gun for people who like high-profile weapons, it compensates for the weight.

It’s the most expensive one out on the list and not apt for beginners who wouldn’t like to spend a huge sum of money on this product. It might be a good fit for people who have a pocket that matches this hobby.

Reason To Buy

SureFire X300 is the most premium and versatile weapon light for fn 509 tactical.

  • DG and XT remote
  • Ambidextrous switch
  • Durable
  • Compensator
  • Expensive

Buying Guide

Beam patterns

One thing that you must consider is the beam pattern of light. It shouldn’t only have a bright central spot and a wide spill around the edges for maximum situational awareness. For this purpose, the best pick for you would be Streamlight TLR-HL with 1000 lumens and 20000 candelas, incredible for a weapon light.


Since Fn 509 tactical is most commonly known for its use in tactical or combat situations, a light that provides a long run is the most effective. All the lights from Streamlight have 1.5 hours of battery life. Also, check out the additional battery features like the rechargeable one in Olight PL-mini 2 Valkyrie.


There are many times when you’re going to drop the weapon or the light itself, especially in critical combat or defense conditions. So, you need something with a great build and excellent water and shock resistance. All the lights mentioned are IPX-7 waterproof except one that’s IPX-6 waterproof.


Last but not least, do keep your budget into consideration and always weigh the features with the price. You don’t want to waste a good load of money on a useless light. Streamlight TLR-7 is the cheapest yet extremely efficient light among the ones mentioned in the list.

But also, I believe in Buy Once, Cry Once rules. A light that’s relatively more expensive than the other three lights – leaving surefire out – but has excellent features is our top pick Streamlight TLR-1 HL.

Bottom Line

Now I hope you have made up your mind about which light you’d like to buy for your Fn 509 Tactical. If you still have any queries, head on to the FAQs.
