What does 10 lumens mean？

What is a Lumen?

• A lumen is the SI unit of luminous flux, representing how much light the human eye perceives from a source.
• 10 lumens= A relatively low brightness level, suitable for subtle or ambient lighting.

Practical Examples for Context

• Flashlight: A 10-lumen flashlight is dim, useful for reading a map in the dark but not for illuminating large areas.
• LED Bulb: A 10-lumen bulb is very weak (typical household bulbs range from800–1,600 lumens).
• Night Light: Many small night lights emit around5–20 lumens, making 10 lumens appropriate for this purpose.

Comparison to Common Light Sources

Source	Approx. Lumens
Candle	~10–15 lm
Smartphone Flash	~30–50 lm
60W Incandescent	~800 lm

When comparing brightness, it is also important to note that LED screens are usually measured in nits rather than lumens, because they are viewed directly as illuminated surfaces. For commercial signs, retail stores, stages, and outdoor advertising, a high-quality LED screen can provide strong visibility even in bright environments.

GGJIA's Service and Experience

At GGJIA, we aim to provide you with the best service and experience. We conduct simulations and create layouts for your building or shop to assist you in determining the number of lights needed, their spacing, recommended wattage, and color temperature (adjusted to your preference). Additionally, we provide a visualization showing how your space will look with the proposed lighting and the corresponding foot candles on the surfaces.
