BenQ ScreenBar Halo vs Logitech Litra Glow Comparison

BenQ ScreenBar Halo

Dual-colour LEDs adjust from 2700 K to 6500 K, with a CRI of 95 or higher. BenQ rates illuminance at 800 lux at 45 cm, covering 63 x 40 cm at 500 lux. A rear backlight lights the wall behind the monitor, which acts as bias lighting and reduces the contrast between a bright screen and a dark room.

Logitech Litra Glow

Logitech's TrueSoft technology uses full-spectrum LEDs behind a diffuser, aimed at natural-looking skin tones. It works as a small key light, putting soft light on the face from the front. Spec-based reasoning: more light on the face lets the webcam use less gain, which reduces image noise. For a bigger setup, the Elgato Key Light Air covers more area but costs more and uses a desk clamp.

The bar is aluminium, with an asymmetric optical design that throws light down onto the desk rather than onto the screen. A counterweight clamp holds it on the monitor. The clamp fits flat and curved monitors, including curved displays from 1000R to 1800R. The single USB-C lead is the only cable to the monitor; the controller is wireless.

Logitech Litra Glow

The light weighs 99 g, or 177 g with the monitor mount. The frosted diffuser softens the LEDs into an even, wide panel of light. The mount clips to most monitors and laptops and swivels 360 degrees. Remove the mount and a 1/4-20 thread takes a tripod or arm. The power and brightness buttons sit on the back edge.

There is no app: brightness, colour temperature, auto-dimming and the backlight are all set from the wireless controller.

Logitech G HUB adds presets and on-screen control for brightness and colour temperature.

BenQ lists monitor thickness ranges of 0.7 to 6 cm for flat screens and 1.6 to 3.8 cm for curved screens. Because it sits on the monitor, it can block a webcam clipped on top. Mount the webcam on a separate arm or below the screen if both are needed.

The mount fits most monitors and laptops, with a 4 inch vertical telescoping extension, a 2 inch horizontal extension and 360 degree swivel. On a monitor that also carries a webcam, the telescoping arm lifts the light above the camera. As a USB-powered light it also runs from chargers and hubs, and with the mount removed it fits small tripods.

Installation is tool-free: place the clamp on the monitor and connect the USB-C cable to a port or adapter. Power draw is up to 6.5 W at 5 V 1.3 A. If a monitor's USB port can't supply that, a phone charger can power it instead. The wireless controller runs on three AAA batteries, and its dial adjusts brightness without reaching up to the monitor.

Logitech Litra Glow

The light connects with a 1.5 m USB-C to USB-A cable. Plug it in, clip it on and it turns on with the power button on the back. Buttons on the back adjust brightness and colour temperature, so software is optional. Logitech G HUB adds presets and syncs settings for streaming.
