ELTIM products can be purchased by contacting our sales team.
ELTIM offers installation of our luminaires. We recommend having a licensed professional install the fixtures.
50,000 hours would imply 5.7 years if the lights are operated 24 hours a day, 7.6 years at 18 hours a day, and 11.4 years at 12 hours a day.
The thermal management of the LEDs. If the LEDs come on a standalone chip, appropriate heat sinks have to be designed to prevent premature failure. Running LEDs at currents higher than specified make the LED run hot. This can happen with mismatched drivers. For example, if the driver produces 700mA but the LED needs 350mA, this will put stress on the LED and reduce its lifespan. Higher ambient temperatures than the ones the LED is rated for will reduce its expected lifespan.
When comparing the lumen output between LEDs and conventional light sources, LEDs may have lower lumen values in many cases. However, LEDs are directional light sources, and so all the lumens emitted from an LED are directed towards the task area. Conversely, conventional sources emit light in all directions. The light is then modulated in a given direction with optical systems like reflectors and lenses. The amount of lumens that fall in the intended task area from an LED light source is greater than that of a conventional light source.
This may occur if you are using the same product from the same brand, with the same optics and hardware. However, in general, the nature of the components (like the optical system, the heat sink, the LED chip, and the driver) affects the output more than the wattage does. A 3W LED luminaire from one manufacturer will have a different output than a 3W LED luminaire from another manufacturer, even if the same LED chip is used. Hence, using a high-quality chip alone does not guarantee better performance. Note that as the wattage increases, the efficiency drops slightly. An LED driven at 3W will emit slightly less than three times the output of one driven at 1W.
Unlike discharge lamps, LEDs are semiconductors and their life span is not affected by the number of times they are turned on and off.
The two numbers following “IP” (Ingress Protection) refer to how much protection they offer from both intrusion and moisture. 6 = totally dust-tight and 5 = protection from low-pressure water jets (all directions).

CRI is the color rendering index. It is a measurement of light quality. Whereas lumens is a measurement of light quantity, CRI measures light quality. It is a scale between 0 and 100, in which 0 is poor quality and 100 is excellent. LEDs are typically in the 70–95 range. The higher the CRI, the more expensive the LED chip, and therefore the more expensive the product itself.
