A typical consumer LCD television shines with 300–500 nits, a professional office monitor with 350–450 nits, and an OLED TV in HDR mode with 600–1,500 nits. A professional indoor LED wall typically ranges between 800–1,500 nits, in shop windows it reaches 2,500–4,000 nits due to stray light, and an outdoor LED totem operates at 5,000–10,000 nits.
It is important to understand: brightness is not a case of "more is always better". A lobby wall that is too bright causes glare, wastes electricity, generates heat, and accelerates LED ageing. The correct value depends on the ambient light — measured in lux. Rule of thumb: the display should be roughly 3–5× brighter than its surroundings. In a 500-lux office, 1,500 nits are sufficient; in 50,000-lux sunlight, 6,000+ nits are required to remain legible.
Professional systems regulate brightness automatically via ambient light sensors (auto-dimming). This extends the LED lifespan (typically, brightness specifications are measured at 50% lifespan — running permanently at 100% halves the usable hours) and saves significant electricity.
Be careful when comparing: some manufacturers specify peak brightness (achievable for short periods in HDR highlights), while others specify sustained brightness (permanent in full screen). For most signage and LED wall applications, sustained is the more honest comparative value.
