Flicker is the one lighting defect almost nobody can name but many people feel — tiredness, distraction, a faint shimmer on a screen. A 2026 generation of constant-current driver chips finally makes flicker-free the default instead of the premium.
Where flicker comes from
Flicker is a driver problem, not a bulb problem. A cheap driver rectifies mains power in steps the eye can sense, especially at low dim. A good constant-current driver smooths that into steady light the eye cannot track.
The metric buyers can request
Ask for a flicker percentage or a PWM frequency figure. A lamp specified under a few percent flicker at full and dimmed output is a different product from one with no number at all, and the difference shows up on video calls and in headache complaints.
- Flicker percentage at 100% and at dimmed output
- PWM frequency, quoted not implied
- Behaviour through the full dim range, not just the top
Why it matters beyond comfort
In hospitality and office settings, flicker is a productivity and review risk. A venue that looks fine in person can read as unstable on a phone camera, which is exactly where a buyer's customer judges it now. For broadcast, training-room or retail-floor use, ask for a measured flicker figure as a line item rather than a marketing phrase like 'eye-friendly', which carries no number behind it.
No flicker figure on the sheet usually means no flicker figure was measured.
Frequently asked questions
Can you see LED flicker?
Most people do not see it directly, but many feel it as eye strain or distraction, and cameras pick it up reliably — which is why a quoted flicker figure matters.
Does dimming make flicker worse?
It can, on a poor driver. A quality constant-current driver keeps flicker low through the whole dim range, not only at full output.
