How to Identify Dimmable LEDs | Differences from Non-Dimmable LEDs and Precautions to Prevent Flickering and Malfunctions
Thank you for always choosing CTSH LIGHT. A "dimmer switch" allows you to freely change the atmosphere of your room. While it is a convenient feature, did you know that using the wrong light bulb can cause flickering or prevent the light from turning off completely?
■ The difference between "dimmable" and "non-dimmable" LED bulbs contain an internal electronic circuit that controls the brightness.
-
Dimmable LEDs: They are designed to correctly read the voltage changes sent from the switch and smoothly adjust the brightness.
-
Non-dimmable LEDs: Because they are designed to shine at a constant voltage, using them with a dimmer switch may cause them to turn off suddenly, flicker severely (flicker phenomenon), or remain faintly lit even when turned off (pseudo-off state).Depending on the electrical environment, they may also react to the weak current of a firefly switch.
■ Key points!
-
Is it okay at "100% brightness"?: You might think non-dimmable bulbs can be used if the dimmer switch is set to maximum, but because the switch is always performing minute control, you should basically **always use a dimmable bulb in a circuit with a dimmer switch.**
-
What about CTSH lighting fixtures?: The lighting fixtures themselves (sockets and cords) are compatible with either type of bulb. What matters is the combination of the "wall switch" and the "light bulb."
■ The appeal of lighting expanded by dimming One of the joys of lighting is changing its expression by adjusting the intensity and color of the light. By choosing a "high color rendering" and "dimmable" bulb, you can make the expression of the light more dramatic, from a candle-like soft glow when watching a movie to a vivid warm tone when eating.
Pre-purchase checklist
-
Is the wall switch a "rotary type" or "slider type" dimmer?
-
Does the packaging of the bulb you selected have a "dimmable" mark?
Even if you went through the trouble of installing a dimmer switch, you won't be able to dim the light. Remember that you need a dimmable bulb in that case.
