Flicker in lighting often arises from variations in power supply stability. This concern is more relevant for LED products operating on AC power. At LUMEBOX, we are proud to operate on DC power (battery), effectively mitigating flicker-related issues. You may occasionally observe slight flickering for 1-2 seconds when switching between modes, a normal part of the power transition between electrical circuits. This transient flicker is generally harmless, unless you have hypersensitivity to it. In some cases, hypersensitive individuals may experience headaches when exposed to prolonged flickering, especially at lower flicker rates below 120Hz. Some companies claim to be 'low flicker,' but this term can be misleading, as even lower flicker rates (below 60Hz) are detectable to the naked eye. A more precise measure of flicker is through waveform and flicker index assessments. Fortunately, with LUMEBOX, a DC-powered device, you won't need to delve into these complexities, unlike larger AC-powered panels that rely on wall sockets.
