SENTINEL™ ESSENTIAL · DUAL-LIGHT SCREEN BAR
Sentinel™ Essential adds focused light to the work in front of your screen and a softer layer behind it—creating a more balanced visual environment for reading, learning and focused work.
BALANCED WORKSPACE
A forward task light illuminates the keyboard, notebook and work surface. A rear glow helps keep the area around your display from feeling visually abrupt after dark.
CRI ≥ 95 FRONT LIGHT
High color rendering helps books, notes, sketches and everyday materials look more faithful and clear—so your desk light does not flatten the details you need to see.
LIGHT FOR THE TASK
Move between 3100K warm, 4200K neutral and 6400K cool light. Then fine-tune brightness with stepless dimming and return to your last setting with memory mode.
DESIGNED FOR LONGER HOURS AT THE DESK
Sentinel™ Essential is built to keep your desk clear while giving the work around your monitor a more complete, comfortable layer of light.

Fit & setup
A quick guide to mounting, power and what is included—so you can know exactly what to expect before you bring Sentinel™ Essential to your desk.
Will it fit my monitor?
The mounting clip sits on top of a compatible flat monitor. The light is designed to stay centered, with its main beam directed down to your desk.
What do I need?
No complicated installation. Just a USB power source and a few simple setup steps.

Then your preferred light setting is remembered for next time.
Connect the clip to the light bar, then position it at the center of your monitor with the main light facing down.
Plug the cable into the light, then into your computer or a suitable USB power source.
Choose front or back illumination, adjust brightness and color temperature, and let memory mode keep your last setting.

A bright screen can make the rest of a desk feel visually abrupt after dark.
Sentinel™ Essential adds focused light to your keyboard and notes, with a softer glow behind your display—so the workspace around the screen feels more complete.
Standard LED lighting distorts color. The Sentinel™ Bio-Nurture delivers a CRI 95+ sun-like spectrum that renders every shade — from the warmth of amber to the precision of clinical white — exactly as nature intended. For designers, photographers, and anyone who needs to trust what they see on screen, this is the difference between guessing and knowing.

Yes. The Sentinel™ Retinal Defense Beam is designed to work with virtually any laptop or external monitor with a screen thickness of up to 10mm. This includes all current MacBook models (Air and Pro), Dell XPS, Lenovo ThinkPad, HP Spectre, and most standard external monitors. The silicone-lined clip holds securely without scratching your screen bezel.
The Sentinel™ uses a weighted counterbalance clip system — the same mechanism used in professional monitor lights. You simply place the clip over the top edge of your screen, and the internal counterweight holds it in position without any clamps, screws, or adhesive. It takes about 5 seconds to attach and can be moved between devices instantly.
Both. The Sentinel™ connects via USB-C (5V/1A) and includes a USB-A adapter in the box. You can power it from your laptop's USB-C port, a USB hub, a wall adapter, or any standard USB power source. It does not require a dedicated power brick.
The Sentinel™ is optimized for screen-mounted use, but it can be placed on a flat surface using the included base stand (included in select configurations). When used as a standalone lamp, it delivers the same CRI 97+ full-spectrum output and 2700K–6500K color temperature range — making it a capable task light for reading, sketching, or keyboard work even without a monitor.
The Sentinel™ covers 2700K (warm amber, ideal for evening work and relaxation) through 6500K (crisp daylight, ideal for focused daytime tasks and color-accurate work). Control is via a single precision stepless dial on the lamp body — rotate clockwise to increase brightness, counterclockwise to shift color temperature. There is no app required and no Bluetooth pairing needed. Analog control, instant response.
PRODUCT DETAILS
Sentinel™ Essential brings focused task light to your keyboard and desk, with a soft backlight behind your display—without taking up desk space.
WHAT IT ADDS TO YOUR SETUP
Most desk lights brighten the work surface but leave the area behind your monitor visually flat. Sentinel™ Essential combines a forward-facing screen light with a rear ambient light, creating a more complete lighting layer around your display.
Use the included wireless remote for easy adjustments from your desk, or use the touch controls on the light bar itself.
