Monitor lights — also called screen light bars — clip to the top of your monitor and illuminate your desk without creating screen glare. They're one of the most overlooked desk upgrades, dramatically reducing eye strain during long work sessions.
These are the best monitor lights in 2026, from the benchmark BenQ ScreenBar to excellent alternatives at a fraction of the price.
What to Look For
- No-Glare Design: The defining feature of monitor lights is asymmetric illumination — they light the desk below while reflecting nothing onto the screen. This is what makes them different from a regular desk lamp.
- Color Temperature Range: Adjustable color temperature (2700K–6500K) lets you match ambient lighting conditions. Warmer for evenings, cooler for focused daytime work.
- USB vs. AC Power: USB-powered lights draw from your monitor's USB port — no separate power adapter needed. Some high-brightness models require AC power.
- Control Method: Physical dial/button is the simplest. Touch-sensitive control strips are sleek. Wireless remote controllers are convenient. App control adds complexity for marginal benefit.
- Brightness (Lux): 500+ lux at the desk surface is sufficient for reading and writing tasks. Higher is better for detailed work like PCB inspection or drawing.
