Discover how steady, flicker-free LED light at 2000K-2700K helps with eye strain relief and creates a calmer atmosphere.
Flicker is the rapid fluctuation of light output, often too fast to see but still registered by the eye and nervous system. It usually results from unstable current, low-quality drivers, or incompatible dimmers.
Common Causes
- Non-compatible dimmers (older halogen or leading-edge types)
- Basic driver circuitry in cheap bulbs
- Voltage instability
- Running too few bulbs on a high-rated dimmer
Dulora's Approach
Most Dulora bulbs are engineered flicker-free using constant-current drivers, tested to IEC TR 61547-1 flicker and stroboscopic standards, with full-range 0-100% dimming without visible ripple. Look for the Flicker-Free icon under Features on the product page.
How to Check if Your Lighting Flickers
- Record it with a smartphone camera in slow motion, moving bands or pulsing indicates flicker.
- Confirm the bulb specs list "Flicker-Free" or "Pst < 1 / SVM < 0.4 compliant."
- Use an LED-rated trailing-edge dimmer rather than an old halogen one.
Best Lighting for Low Eye Strain
The most comfortable colour temperature range for relaxed vision is 2000K-2700K, warm tones close to firelight, which help the body wind down in the evening.
