Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your SCS Enterprises Total Invisible 940nM IR Light Bulb Lamp. This device is designed to enhance the night vision capabilities of compatible security cameras by providing an invisible infrared light source. Please read these instructions thoroughly before use.
Product Overview
The SCS Enterprises 940nM IR Light Bulb Lamp is a specialized infrared illuminator featuring 6 high-power LED elements. It is engineered to emit 940nM wavelength infrared light, which is generally invisible to the human eye, providing discreet illumination for night vision cameras.

Key Features:
- Invisible 940nM IR: Provides illumination that is generally undetectable by the human eye.
- Wide Angle Coverage: Offers a 160-degree beam angle to cover a broad area.
- Extended Range: Effective range up to 20 feet, with an optimal range of 15 feet (results may vary based on camera sensitivity).
- Low Heat Operation: Designed with a heat sink for efficient heat dissipation and long-lasting performance.
- Standard E26 Base: Compatible with standard American E26 light sockets.
- Indoor Use Only: This device is intended for indoor applications.

Setup and Installation
- Power Off: Ensure the power to the light socket is turned off before installation.
- Screw In: Carefully screw the SCS Enterprises 940nM IR Light Bulb Lamp into a standard E26 light socket.
- Optional Gooseneck Adapter: If additional positioning flexibility is required, attach the provided 4-inch flexible gooseneck extension adapter to the E26 socket first, then screw the IR bulb into the adapter.
- Power On: Restore power to the light socket. The IR bulb will illuminate.

Important: This IR bulb is designed for indoor use only. Do not install in outdoor fixtures or areas exposed to moisture.
Operation
Once installed and powered, the SCS Enterprises 940nM IR Light Bulb Lamp operates continuously. It does not feature a light sensor for automatic on/off functionality. The infrared light it emits is intended to be invisible to the human eye, providing supplemental illumination for compatible night vision cameras.

Figure 4: Range Diagram. This diagram illustrates the optimal and effective range of the IR light bulb, indicating an effective range of 20 feet and an optimal range within that, emphasizing that actual range depends on the camera's light sensitivity. It also suggests using a reflector to increase range.
Compatibility
This IR illuminator is specifically designed for use with 940nM IR capable cameras.
- 940nM Cameras: For cameras equipped with a 940nM IR filter, this lamp will provide optimal night vision enhancement, allowing the camera to "see" in total darkness with minimal to zero visible glow from the IR source.
- 850nM Cameras: While the bulb may function with 850nM cameras, the infrared effect will be significantly lessened (approximately 30-50% reduction in effectiveness). 850nM IR LEDs typically emit a faint red glow, which may be visible.
To determine your camera's compatibility: If your camera's built-in IR LEDs remain completely dark at night, it likely has a 940nM IR filter. If the LEDs emit a visible red glow when viewed directly, it is an 850nM system.
Maintenance
The SCS Enterprises 940nM IR Light Bulb Lamp requires minimal maintenance.
- Cleaning: Ensure the bulb is powered off and cool before cleaning. Gently wipe the glass cover with a soft, dry cloth to remove dust or smudges. Do not use liquid cleaners or abrasive materials.
- Longevity: The quality LED elements are designed for long-lasting operation. Avoid frequent power cycling if possible to maximize lifespan.
