Lighting up the future

LED light advantages

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.

Colour Diodes



  • Longer life (can reach up to 100.000 h depending on quality and functional conditions)
  • Reduced maintenance costs
  • Lower consumption than incandescent and halogen lamps at a time when energy costs are still an upward identified trend
  • Substitutes of fluorescent lights do not require the use of ballast or starter (adding power consumption savings and avoiding malfunctions for ballast and starter failures)
  • They can use high-efficiency plastic optics



Operating Conditions and Temperature

  • Capable of turning on at low temperatures (typically at -20 º C, but can be designed to reach -40° C) with high efficiency
  • Works at low DC voltage
  • Sealed for life in waterproof luminaires



Architectural and Lighting Design

  • Flexibility in the design of hidden lights
  • Saturated colours without using filters
  • Direct light that increases the efficiency
  • Robustness and security against vibration (solid-state source)
  • Minor light scattering at the upper hemisphere due to better optical control
  • Dynamic light, with the possibility of changing the white point
  • Total adjustment without changing colour
  • Instant Start 100% light
  • Without loss because filters



Environment and Health

  • CE and ROHS compliant
  • Do not contain mercury
  • Do not contain lead
  • Produce less CO2 emissions (less energy consumption)
  • No IR or UV radiation (halogen lamps have high UV output)
  • The raw materials generally used (PCB, aluminium, magnesium, etc.) cannot break like glass and are easily recyclable



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.

LED's light

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:

  • Warm White (Tc <3.300K)
  • Natural White (3.300K <Tc <5,000 K)
  • Pure White (Tc> 5,000 K)


At 3elamp we adjust the colour temperatures according to the customer requirement.
