Lux vs Lumen Projector: What is Better?

Lux vs lumens projector? Nowadays, consumer electronics want a better understanding of the product specifications before making a purchase. The couple of terms that confuse many projector buyers are lux and lumen and these variations have a significant impact on the quality and price of the projection unit.

Speaking of confusion, the lux and lumen projector have particular specifications that are too complicated to comprehend for not-so-tech-savvy consumers.

For the home theater setup and office use, the consumers take into account the projector brightness to make an informed decision.

Lux vs Lumen Projector

The main difference between the lux and lumen projector is the quantification of brightness.

These units measure the brightness of the projector lamp and how it is perceived by the human eye.

Lux vs lumen is a concept that most people do not know much about. First of all, lux and lumens indicate the light output of the projector and have a huge role in determining the clarity of the projected images.

Projector brightness is measured in lux, lumen, and ANSI lumen, each of these units shares many similarities and a few differences. To get a deeper understanding, know a little more about lumens and lux.

About Lux

Lux can be expressed as the brightness measured in terms of the surface area. It refers to the measurement of the intensity of light (as the human eye’s perception) by how much light illuminates the surface. Further, it is an International System of unit (SI unit) measuring brightness.

About Lumen

A lumen is a unit of measurement that measures the amount of light emitted by the light source that reflects in all directions after considering the human eye’s sensitivity. Lumens measure luminous flux, and similar to Lux, it is also an SI unit.

Difference Between the Lumen and Lux Projector

Lumen is the amount of light produced by the light source per unit of time. It is different from the radiant flux and measures electromagnetic waves visible to the human eye only.

It is an SI unit for the luminous flux that a lamp of one candela of intensity radiates over a solid angle of one steradian. Besides projectors, it is used to measure the light output of other lighting equipment.

Conversely, lux is a unit of measurement that measures the light output over surface area or 1 lumen per area.

Importantly, lux is dependent on lumen and lumen is independent of lux. In terms of projection units, it is referred to as the lumen per square meter.

As recent studies tell, measures how light reflects on the surface and how the human eye perceives light intensity.

Fundamentally, both lumen and lux are closely related and used for measuring light output in two different contexts.

Simply put, the lumen is the amount of brightness from the light source considering human eye sensitivity. On the contrary, lux is how bright the light is after it spreads over the surface.

While measuring from the fixed source, lumens sustain a constant number, however, lux decreases as the lumen increases.


Lux vs Lumens – Which is better?

Interestingly enough, lux and lumen share several commonalities. For instance, both are SI units of brightness and quantify projector brightness in two varying contexts.

When it comes to investing in a projector, lumens should be your priority. Lumens remain the same no matter what the distance. To summarize, lumen measures the projector brightness and lux is the amount of brightness perceived by the human eye.

It is better to choose the projectors with lumens as they are more stable. On the other hand, lux changes according to the screen size and the distance.
