Desk lamps light your monitor. The ScreenBar Halo lights your desk and deliberately does not light your monitor, which removes the glare that makes evening work tiring.
The auto-dim sensor measures ambient light and holds the desk at 500 lux, and the backlight glow behind the monitor reduces the contrast between screen and wall. Colour temperature runs 2700K–6500K.
The wireless puck is the bit you will actually appreciate day to day — no reaching over the monitor.
