Buying Guide
- Brightness and lumens: For offices and schools, aim for 3,500–5,000+ lumens per fixture depending on room size and ceiling height.
- Color temperature: Choose 3500K–5000K for most work areas; 4000K is a common compromise between tasks and comfort; 5000K–6500K is best for high-contrast, task-focused spaces.
- Wattage and efficiency: Look for high efficacy (lm/W) and total wattage that matches your current power budget for the space.
- Dimming and controls: If you need flexible lighting, prefer 0-10V dimmable drivers and compatible control systems.
- Installation approach: Magnetic retrofits offer quick installs; center-basket designs promote uniform light with fewer shadows.
- Durability: Look for long lifetimes (50,000+ hours) to minimize replacement frequency in commercial settings.
- Voltage compatibility: Ensure the fixture supports your site voltage (commonly 120–277V in the US).
