Flicker might not grab headlines, but in 2025, it’s a key challenge in lighting design. As spaces are valued for comfort and aesthetics, this subtle flaw can undo even the sharpest designs. At 299 Lighting, we’re the experts who tackle flicker, ensuring your projects don’t just dazzle but feel exceptional too.
What Is Flicker? And Its Causes
Flicker is when a light source, usually an LED, flips on and off at speed. It’s not always blatant, like a sputtering fluorescent tube; often it’s invisible, pulsing too fast for your eyes to catch. Three types stand out: visible flicker (the obvious buzz), stroboscopic effects (making motion look choppy), and invisible flicker (a silent stressor). What sparks it? Shoddy drivers or power mismatches. LEDs crave direct current (DC), but mains supply feeds alternating current (AC) at 50Hz in the UK. A weak driver can’t iron out that wave, leaving light pulsing at 100Hz or more. Cheap circuits, dimmer incompatibilities, or outdated tech pile on the problem. Pinpointing these triggers is step one to killing flicker dead.
Effects on the Body
Flicker hits harder than you’d think. Visible flicker at low frequencies (below 80Hz) tires your eyes fast, leaving them strained and gritty. Invisible flicker, even at 120Hz, messes with your head: think nagging headaches, foggy focus, or that vague “off” feeling after hours in a room. Stroboscopic effects are nastier, distorting motion so a spinning fan looks frozen, a hazard in places like factories. Studies tie long-term exposure to fatigue, even migraines in sensitive folks. It’s not just discomfort, it’s a slow drain on wellbeing and productivity, making flicker a foe worth fighting in any design.
Defining Flicker-Free and the Standards
Flicker-free lighting is pure, steady illumination with zero pulses. It’s about drivers that nail the AC-to-DC switch, pushing frequencies past 200Hz where flicker vanishes from perception. Some top drivers hit 3000Hz or more, leaving no trace. The EU’s got rules for this: COMMISSION REGULATION (EU) 2019/2020, rolled out in 2021, sets Pst LM ≤ 1.0 for short-term flicker (how annoying it feels) and SVM ≤ 0.4 for stroboscopic visibility (motion clarity). Beyond Europe, IEEE 1789 suggests flicker stays below 8% at high frequencies for health’s sake. Leading driver makers churn out compliant gear, from basic flicker-free to premium models that double as dimming champs. It’s the backbone of spaces that don’t just shine but soothe.
