Streamlight TLR-7X vs. TLR-7A – Choosing the Right Pistol Light

Writer's picture:  TH Holsters TH Holsters

Introduction

Streamlight TLR7X

When it comes to compact weapon lights, the Streamlight TLR-7 series has been a top choice for handgun owners. Known for their small footprint, reliable performance, and wide holster compatibility, the TLR-7A and the newer TLR-7X both offer solid illumination options.

But how do they compare? Whether you’re running a standard CR123A battery or the new rechargeable SL-B9 battery, understanding the differences between these two models can help you decide which is the right fit for your setup. Let’s break down their performance and practical use.

Design and Compatibility

Both the TLR-7A and TLR-7X share identical dimensions, meaning holster compatibility is the same. If you already own a holster designed for the TLR-7A, it will also fit the TLR-7X without issue. This is a huge advantage for those looking to upgrade their light without having to replace their carry setup.

At TH Holsters, we design our light-bearing holsters to work seamlessly with both models, ensuring a secure fit and easy draw for everyday carry, duty use, or range training.


Light Output: Lumens and Candela

Lumens

The primary distinction between these two models comes down to battery options. The TLR-7X is compatible with both standard CR123A batteries and the rechargeable SL-B9 battery, while the TLR-7A only supports CR123A.

  • With a CR123A battery, both models perform similarly, maintaining a steady and reliable beam.

  • The TLR-7X offers a slight boost in output in the first ten minutes when using the SL-B9 battery, but the difference is minimal in practical use.


Candela

Candela measures the light’s intensity and ability to project at a distance. While Streamlight advertises 5,000 candela for both models, real-world tests show slight variations:

Model

Candela (Initial)

Candela (30s)

TLR-7X (SL-B9)

4,488

4,067

TLR-7X (CR123A)

3,916

3,873

TLR-7A

3,914

3,748

Overall, both models perform nearly the same, with minor variations that won’t make a noticeable difference in everyday use.
