 Side By Side - TLR 7 Sub VS TLR 7 A

Check out our complete TLR 7 A VS TLR 7 Sub to see more side by side comparison

Streamlight TLR 7 SUB is basically a TLR 7 A with a smaller body.

Same battery, Same LED size, Same Switch Module

Modes Of Operation

  • Single click - Constant on
  • Press & Hold - Momentary
  • Strobe - Double press

Note: To activate the strobe mode on TLR 7 (TEN TAPS programming), press one of the toggle switches 9 times, hold on the 10th press until the light flashes then off. Do the same to reverse the programming

When the strobe mode is activated, you can still operate constant on and momentary modes as normal.

NEW TLR 7 SUB features the same ambi toggle switches that gives the shooter better control with the firing hand and the support hand.

Operating the light with one hand is very doable without exerting any finger pressure compare to other lights on the market.

It's reachable for shooters with various hand sizes, and it gives very positive click feedback.

Lumen & Candela

The TLR 7 Sub can output up to 500 lumens & 5000 candela on a fully charged CR123A battery, and it's best used for illuminating targets of interest in low light up to 7-40 yards with maximum light beam brightness & hot spot.

The 500 lumens can lit up everything nearby, but at a distance of up to 70 yards max the user wouldn't be able to clearly see besides the dimmed silhouette.

Lumen intensity is important, but Candela is king when it comes to identifying targets at longer distances.

Under ambient lights or fog, the most effective light can reach roughly about 16 - 20 yards.

For personal defense engagement distance, the TLR 7 can lit up the scene and the user can clearly see the target in low light, and ID what the person is holding in their hands to make the best judgement.

Beam Pattern & Color Tint

The TLR 7 Sub has a balanced focused hot spot & flood beam optimized for close-range handgun light applications up to 30 yards.

It's effective to blind a threat with the hot spot, and use the flood beam to lit up the surrounding for max situational awareness without directly pointing the light at the subject.

The beam is slightly brighter than the TLR 7A, and this time it has a neutral tint for more accurate color rendition in low light (Important for accurate target identification).

The light uses a single CR123A battery that lasts about 90 mins. Any CR123A batteries on the market will work.

To install the battery, the LED head has to be removed first, then insert the battery into the body.

What can be improved ? - As the weapon light technology advances for higher lumens & candela ratings, we are looking forward to seeing the Streamlight TLR 7 evolve into the use of a higher output rechargeable battery for higher lumen & candela output without increase in its overall size.

Safety Mode

The TLR7 Sub features the same safety mode as the TLR7A and TLR8 models.

The LED lens bezel can be completely shut off simply by following the detent instruction on the red label.

Water sealed O Ring included (IPX7 Rated)

Once you're familiar with the feature, you can take the sticker label off.

The main purpose of this feature is to prevent accidental light discharge while carrying it in a holster to prevent battery loss, where the toggle switch can bump into clothing or other things without the user knowing.

Based on our initial impression, this feature can cause the user to forget to turn it back on and get surprised by it in an emergency situation.

We highly recommend leaving the safety off and use a good holster so you don't run into this problem.

Mount & Rail Keys

The TLR 7 SUB are sold separately for 3 different versions:

  • Glock
  • M1913 (Fits more gun frames than subcompact)
  • P365

The Glock version actually uses the same key #1 from the M1913 version, but the clamp size is different. See picture above.

Overall, the light body is the same for all 3 variants, and I believe this is a way to generate more revenue for Streamlight if end users have multiple sub compact handguns.

If you own most subcompact pistols, it can be costly to buy multiple TLR 7 Sub.

Hopefully these rail keys will be available for sell separately in the future.

The TLR 7 Sub is made out of 6061 T6 aerospace aluminum. Under normal use the light will last you a long time.

If you use the light for airsoft or simunition training, the lens will crack upon direct impact.

The lens bezel head has built-in threads that goes onto the body of the light. So in the event that the lens break, the light head can be replaced via Streamlight's Limited lifetime warranty.

IPX7 waterproof to 1m for about 30 minutes, meaning the light can withstand water splashes, but not recommended for water submersion.

Final Verdict

This is an absolutely must have subcompact pistol light for the price. Even though it doesn't come with all the rail keys, the light itself is just like an smaller TLR7A.

Overall, the TLR 7 Sub works on subcompact pistols, PCCs and even full size handguns. It's by far the best looking and compact light for conceal carry.

We are excited to see future TLR 8 SUB with laser feature.


  • Reduced overall size profile for conceal carry & faster holstering
  • Brighter beam than TLR 7A (More netural)
  • Super lightweight
  • Sam beam pattern as TLR 7 for close-range application


  • Have to purchase a new light for different mount keys
  • Still uses CR123A battery (less output)
  • Strobe mode activation is a hidden feature, not obvious to users
