Whether we want to use LED light bulb in our house or in a project, we generally have a complexity like how many watts and lumens that we need. The first question that comes to our mind when buying a LED light bulb is that; Is it enough to light our house?
Whether we want to use LED light bulb in our house or in a project, we generally have a complexity like how many watts and lumens that we need. The first question that comes to our mind when buying a LED light bulb is that; Is it enough to light our house?
Lumen and Watt, one represents light and the other one represents power. Both the consumer and the seller can be confused between these two terms.
In the traditional lighting, power was in the forefront. When comparing two incandescent lamp bulbs, power ratings were taken into account. Actually, it was not wrong. Because how much power meant that much light.
On the other hand, LED technology has brought many innovations. Technological developments have made LEDs more efficient constantly, and increased lumen values. A few years ago, LED with 1W power had a luminous flux of 50 lumen, but today, 220 lumen levels are seen in commercial products.
This shows that it is not right to compare power rating with lighting when it comes to LED lamps and luminaires.
Each producer can use LEDs in different lumen values. For this reason, the 10W LED lamp from two different producers may have different light output. Simply, when a brand’s 10W LED lamp illuminates our room, you may not get the same brightness even if you use two 10W products of the other brand.
Watt is a measure of how much electricity a thing consumes. Lumen indicates the total light output of a light source.
If we need a LED luminaire in a project or a simple LED lamp in our house, what we need to pay attention is the lumen value. If we need LED lamp 1,000 lumen or more, we should pay attention to this value.
Also, here is another point to achieve this lumen value with low power consumption. This is the best explain that by lumen per watt, ie lm/W. But I will try to simplify this a little more.
Two different products, both are 1,000 lumen, which one has less power consumption should be preferred. In other words, one has 10W & 1,000 lumen; and the other one has 9W & 1,000 lumen, 9W should be preferred.
Public institutions should also focus on lumen values when preparing their specification. The maximum power consumption required to achieve this lumen value must be specified in the specification.
