The main advantage of using LED for illumination lies in the drastic reduction in power consumption and low maintenance they require, but these are not the only ones.

3elamp solutions encompass nearly all of the conventional lamps, and, if there is no solution available, our Product Development Department will create it for you.
This is how we are lighting the future and contributing to a greenest world.
To know the colour perception that is obtained with a lamp, it is not enough to select the commonly called "colour" (which is measured in degrees Kelvin) as the majority of discharge lamps have a discontinuous spectrum (that is, its spectrum does not contain all colours). Depending on the colours contained in the spectrum, the colour reproduction can be from very poor to excellent.
Commonly thought that after choosing the colour temperature, colour perception is determined; but it is not really the case. You must select also the ability to reproduce the colours of the source: the so called Colour Rendering Index (CRI or Ra).
Colour Temperature and Colour Rendering Index are parameters completely independent. Serve as an example to think on the difference between daylight and incandescent lamp. Both have an excellent colour rendition, as in its spectrum are every colour, but the appearance of colour is different, since in the case of sunlight the colour temperature is cold at noon, while the incandescent lamp is warm, so they produce different feelings about spaces and lighted surfaces.
For general indoor lighting applications, DIN 5035 splits light into three main colour categories:
At 3elamp we adjust the colour temperatures according to the customer requirement.
