Streamlight ProTac 1L



Powerful Highs. Purposeful Lows. Plus the extra protection of a Strobe. All from the smallest, lightest—and brightest—lithium-powered handheld tactical lights by Streamlight.

The Professional Tactical (ProTac) family of lights was designed to offer exceptional performance and versatility. Compact & powerful, the ProTac® 1L flashlight offers three different user selectable programs and the latest in power LED technology. The combination of small size and output from the C4® LED result in one of the brightest tactical personal carry lights for its’ size.

Remarkably compact, incredibly powerful, tough enough for extreme conditions and daily use. With High and Low output modes, a powerful tactical strobe, and the latest in high-performance C4 LED technology these advanced personal carry lights outperform lights many times their size and weight.

These ultra-compact flashlights are unsurpassed for ease of carry and useful performance in most day-to-day applications. The extremely bright, smooth tactical beam generated on High power mode offers tactical level illumination for short and medium-range use. And their Low power modes are truly low enough to offer real advantages in most non-threatening situations or where you don’t want to alarm a suspect or disrupt your own night vision. You’ll find it perfect for checking ID, writing a ticket, reading a map, or just finding your way around in a dark area.

The tactical strobe, of course, has the opposite effect. But it can be a lifesaver in many situations.
TEN-TAP® Programming for Flexible Lighting Options: Streamlight makes flashlights for a wide variety of applications, but they understand that not everyone wants the same lighting options.

Do you like most of the features of a flashlight, but not the pre-set programs? Now, with their TEN-TAP® Programming, you can reprogram the light from the standard default option. Reprogramming is easy and can be done from anywhere – with just a few quick taps of the switch you can change the lighting to fit your needs and how you’ll be using it.

With those lights that feature TEN-TAP® Programming, you can choose from three user-selectable programs. The ProTac 1L has the following TEN-TAP® Programming options:
  1. High/Strobe/Low (factory default)
  2. High only
  3. Low/High
General Operation: Some Streamlight flashlights feature a programmable switch with momentary operation (light press or tap) and constant on operation (press until click). Lights are shipped from the factory in the default program. For specific information on your light’s TEN-TAP® Programming, please see the instructions included with your light.

Accessing Other Programs: With lights featuring the TEN-TAP® programmable switch, you are able to select one of three different programs to meet your lighting application needs. To change to the next program, starting from the “Off” position, tap the switch rapidly 9 times (within 0.4 seconds per tap) and hold it down the 10th time. Continue holding the switch until the light turns off (approximately 1 second), and then release the switch. Repeat this pattern to change to the next program.
