FAQs

How many lumens does it take to light a sign?
The number of lumens needed to light a sign depends on factors like the size of the sign, ambient lighting conditions, desired visibility, and distance from the sign. For a small to medium-sized sign, you might need anywhere from 1000 to 5000 lumens.

What is the formula for calculating lighting?
The formula for calculating lighting typically involves factors such as illuminance (lux or foot-candles), area, and the efficiency of the light source. One common formula is:
Illuminance (lux) = Luminous Flux (lumens) / Area (square meters)

How do you calculate light requirements?
To calculate light requirements, you need to consider factors such as the type of activity or task being performed in the illuminated area, the size of the area, required illuminance levels, and any specific lighting standards or guidelines applicable to the situation.

How do you calculate the number of lights?
The number of lights needed depends on factors like the total lumens required, the luminous efficacy of the light source, the distribution of light, and the layout of the space. Divide the total required lumens by the lumen output of each light source to determine the number of lights needed.

How bright should a sign light be?
A sign light should be bright enough to be easily visible from its intended viewing distance and under various lighting conditions. A good guideline is to aim for a luminance level that stands out without causing discomfort to viewers.

Is 1000 lumens very bright?
Yes, 1000 lumens is generally considered bright. It’s roughly equivalent to the brightness of a 100-watt incandescent bulb.

How bright is 10 lumens?
10 lumens would provide a dim, faint light. It’s comparable to the brightness of a candle from a few feet away.

How bright is 50 lumens?
50 lumens would provide a small amount of light. It’s similar to the brightness of a nightlight.

How bright is 4000 lumens?
4000 lumens is quite bright, suitable for illuminating a large area. It’s similar to the brightness of multiple standard household bulbs.

Is there an app to measure lumens?
Yes, there are several smartphone apps available for both iOS and Android platforms that claim to measure lumens using the device’s camera and sensors.

What is the formula for calculating lumens?
Lumens = Illuminance (lux) × Area (square meters)

What is 100 lumens equal to in watts?
The conversion from lumens to watts depends on the efficiency of the light source. As a rough estimate, 100 lumens might be equivalent to around 10-20 watts for incandescent bulbs or around 5-10 watts for LED bulbs.

How do you calculate the number of LED downlights?
To calculate the number of LED downlights needed, divide the total required lumens by the lumen output of each LED downlight, taking into account factors like spacing and distribution of light.

How do you calculate lux level?
Lux level is calculated by measuring the illuminance (lux) at a given point on a surface. This is typically done using a light meter. The formula to calculate lux level is Lux = Lumens / Area (in square meters).

What is the best light for signage?
LED lights are often considered the best choice for signage due to their energy efficiency, longevity, and ability to produce vibrant colors.

What size LED sign do I need?
The size of the LED sign you need depends on factors such as viewing distance, desired visibility, and available space. Larger signs are generally needed for greater distances or to attract attention from a distance.

Which is better LED or neon signs?
LED signs are generally considered better than neon signs in terms of energy efficiency, durability, and versatility. They also offer more options for customization and are often easier to maintain.
