LiMoTest Solar – LIM

LiMoTest Solar – Makes invisible light flicker audible

Simply plug in. Point at the light source. Listen.

The LiMoTest Solar is a simple yet highly effective personal testing device for lamps and screens.

It instantly tells you whether a light source is steady – or flickering.

Not through complex displays or numbers, but directly through sound.

• Silence means: no relevant flicker.
• Audible tones or whistling mean: light modulation is present.

That’s all you need to know.

Why this matters

Many modern light sources – especially LEDs, energy-saving lamps, and screens – do not emit constant light. Instead, they use rapid on/off pulses. This flicker is usually invisible to the eye, yet it can still act as a stress signal for the body.

Common effects may include:

• unconscious stress
• faster fatigue
• reduced concentration
• headaches
• increased accident risk
• changes in retinal blood flow

The sun, our most natural light source, does not flickern.

With the LiMoTest Solar, you can easily compare artificial light sources to this natural reference.

How the LiMoTest Solar works – it’s that easy

1. Plug in the speaker
2. Switch the device on
3. Point the sensor at the light source
4. Listen

That’s it.

• Daylight produces only a soft noise
• steady lamps remain mostly silent
• flickering LEDs and screens generate clear tones – often strongest when dimmed

Within seconds, you know which lights are suitable for you.

Perfect for

• selecting low-flicker lamps
• checking monitors and TVs
• improving your home or office lighting
• making informed purchasing decisions

The LiMoTest Solar is the ideal companion for anyone who wants to take control of their lighting environment.

Optional advanced use

For finer perception, headphones can be connected.

Using an audio cable, the sensor can also be connected to an oscilloscope or a computer for extended analysis.

These features are optional – for everyday use, the included speaker is all you need.

Included

• LiMoTest Solar (photosensitive sensor)
• Rechargeable active speaker
• Charging cable

Conclusion

The LiMoTest Solar makes invisible light flicker audible – quickly, directly, and without technical knowledge.

Plug in. Listen. Decide. Lighting quality doesn’t get simpler than this.
