Light is life when the world goes dim. Whether you’re clearing a hallway at home, stepping off a vehicle at dusk, or running reps on a flat range after sunset, your equipment has to be simple, durable, and bright enough to give you positive identification without adding bulk or snag points.
VIRIDIAN CTL CUSTOM delivers that balance—an ultra-compact weapon light built for the Walther PDP, yet versatile enough to run on any standard 1913 Picatinny rail for pistol, long gun, or helmet use.

Why This Light Matters When Seconds Count
A clean draw, a steady index, and a clear sight picture are only as good as what you can see. The CTL’s 600-lumen output is purpose-built for realistic distances—enough intensity to punch through dark rooms and unlit backyards while still managing spill and splash so you don’t wash yourself out indoors. The goal isn’t to stun; it’s to identify. That’s tactical precision illumination: bright, controllable, and consistent.
Mounted to a Walther PDP, the light hugs the frame and preserves the pistol’s excellent balance. This is where the custom fit pays off—no wobble, no awkward overhang, no wasted space. It tracks with the gun, not against it, and it stays put when you’re moving with intent.
Built for the PDP, Ready for Any Rail
Viridian tailored this CTL variant for the PDP series—a nod to a platform loved for its ergonomics, trigger, and optics-ready slide. But the design doesn’t stop at one host. Because it mounts to any standard 1913 Picatinny rail, the CTL transitions easily from pistol to long gun or even a helmet shroud adapter. That gives you one light you can re-task as your mission or training plan shifts.
On a compact rifle or braced platform, the CTL becomes a clean-side white light with minimal footprint. On a helmet, it’s a lightweight utility illuminator for admin tasks, map reading, and close-in movement. The common thread is simplicity: a single light, multiple roles, minimal complication.
Ultra-Compact Form Factor Without Compromise
Compact is only useful if controls remain accessible under stress. The CTL keeps its profile slim while preserving intuitive activation. The footprint supports holster compatibility for PDP duty and concealment rigs built around compact weapon lights. Less bulk means fewer snags on cover garments, seatbelts, or sling setups.
At 600 lumens, the beam is tuned for practical tasks—clearing and searching inside structures, illuminating backyards or barns, and filling the space between you and your threat area. It’s bright enough to own the dark while staying manageable for two-handed and one-handed shooting techniques.
Details That Serve the Shooter
Positive Target Identification
In low light, ambiguity is the enemy. The CTL’s output and beam pattern help you confirm what’s in a hand, read a face, or identify a doorway cleanly. That reduces hesitation and drives confident decision-making, from home defense to professional duty assignments.
PDP-Centric Fit
Walther’s PDP pistol lines up naturally with the CTL’s compact housing. The fit looks deliberate because it is. The result is a setup that points fast, clears holsters cleanly, and keeps the bore-to-light offset consistent for indexing and training.
1913 Picatinny Versatility
A standard rail interface is the great equalizer. From pistol to rifle to helmet mount, you get cross-platform flexibility without changing batteries or learning new controls. It’s simple, smart, and efficient.
Professional-Grade Value
Viridian has a reputation for practical innovation and duty-ready accessories. With the CTL in the Accessories category, the value proposition lands hard: at a street-friendly $109.00, you’re getting a purpose-built, ultra-compact white light from a known brand without paying a premium for features you won’t use. It’s the kind of gear that makes sense for a first light-equipped pistol or as a second light you can move across platforms when needed.
There’s no assigned caliber or model limitation here—just a clean, adaptable tool designed for light discipline and clarity. Model variations exist, but this variant is the one you want if you’re running a PDP and want an easy pivot to 1913 rails elsewhere.
Real-World Use: From Dry Runs to Low-Light Drills
Success in the dark is earned in daylight. Run your draw with the CTL on the gun until activation becomes second nature. Practice searching with the light held tight to your workspace and avoid painting what you don’t intend to see. On rifles, identify a thumb-over-bore or c-clamp position that lets you ride the switch without over-gripping. On helmets, use the CTL for admin tasks and learn to manage light discipline—on when needed, off when it’s not.
If you’re building a home-defense setup, mount the CTL to your PDP, confirm holster compatibility, and test the setup at dusk. For patrol or professional use, logging reps from cover with clean activation matters. For ranch and property work, the light’s manageable throw handles barn aisles, sheds, and outbuildings without overpowering your sight picture.
