How many LED lights do I need

Properly illuminating a room is more difficult than it might seem. After choosing the type of lighting, the question always arises: How many LED lamps do I need?

Lumen vs lux

With all our LED lamps you can find the light output in a lumen in the specifications. The number of lumens is the total amount of light that a light source emits itself. The number of lumens is important, the higher the light output in relation to the power of the lamp, the more efficient the lamp is.

Just as important but much less known to the general public is Lux. Just like lumen, a lux is a unit of light intensity. The difference with lumen is that the amount of lux indicates how much light ends up on a surface. One lux is equal to one lumen / m 2.

Corporate lighting

A correctly lit workplace is important. Not only is a well-lit workplace conducive to employee well-being, but you also increase the mood, concentration, and productivity of students and employees. But not every workspace needs the same light. The type of light depends on various factors, such as the work being performed. For example, visually strenuous tasks require more light than visually simple tasks. In the European standard NEN-EN 12464-1: 2011nl Light and lighting (Workplace lighting - Part 1: Indoor workplaces) all standards have been laid down. These standards prescribe a specific lux value per space and per square meter. With the formula and overview below you can easily calculate how much light output in lumen you need for a specific room:

number of m2 x number of lux = number of required lumen

How much lux do you need per room? View our overview:

Space                           Lux       Space                         Lux
Office                           500 Canteen                       200
Conference room          500 Toilet                           100

Parking garage             75       Laboratory                    500

Color temperature

In addition, not all workplaces require lamps with the same color temperature. The color temperature keeps the color light in those lamps spreading, expressed in Kelvin (K). This light varies from very warm (2200K) to very cold (6500K). The color temperature you need depends on the situation and space. In the overview below we give you an indication of the number of Kelvin you need per room:

Space                        Color temperature            Space                              Color temperature
Reception hall                      3000                     Relax room or canteen    3000K
Hotel room                      3000K                       Retail space                     3000K
Conference room              4000K                     Classroom                        4000K
College room                      4000K                   Stairwell                           4000K
Gang                              4000K                        Conference room             4000K

LED panels

LED panels are most often used in offices and schools. These are environments where productivity and concentration are important. It is therefore important to properly illuminate office spaces and classrooms. At 123led we divide the LED panels into three groups: Basic, High Lumen and UGR.

The Basic LED panels are, as the name suggests, basic LED panels. These LED panels are cheaper in price but have a lower light output in proportion. Due to the lower light output, the basic LED panels are not eligible for the energy investment allowance (EIA). The Basic LED panels are good to use for spaces where work is not directly performed, such as a corridor or small coffee room.

The High Lumen LED panels are specially designed to have the highest possible light output. These LED panels are also more efficient in lumen/watt ratio. This means that these LED panels are eligible for the EIA.

The UGR LED panels have been designed to increase the well-being of employees. These LED panels cause less light pollution. Among other things, this ensures that headaches are prevented for employees. The UGR LED panels also have a more efficient lumen/watt ratio and are therefore also eligible for the EIA.

LED High Bay lamps

Led High Bay lamps are mainly placed in large warehouse or factory halls. For safety reasons and to guarantee the well-being of employees, the right amount of lighting in these types of rooms is important. The spaces all have one thing in common: a high ceiling of at least 4 meters. Because of the high ceiling in the halls, it is therefore important that the light does reach the floor. A well-lit factory hall provides a better view and this increases safety on the work floor. But which LED High Bay lamps and what quantity do you need?
