LED BASICS

  • PRIMARY BENEFITS

    Here are just a few of the primary benefits:

    • Lower energy consumption.
    • Longer service life; LED bulbs can last up to 100,000 hours.
    • Durability; LED bulbs are resistant to thermal, vibrating shocks and turn on instantly from -40°C to 185°C, making them ideal for applications subject to frequent on-off cycling.
    • Flexibility; LEDs allow for directional distribution of light.
    • No infrared or ultraviolet radiation – UV light attracts bugs.
    • No toxic chemicals; LEDs contain no mercury and do not require ballasts, which are often manufactured with PCBs.
    • Very low heat generation; LEDs can reduce climate control costs and are especially suited for cold storage facilities.
    • No frequency interference; no ballast to interfere with radio and television signals Wide range of color; LEDs can be manufactured to produce all colors of the spectrum without filters as well as white light in a variety of color temperatures.
  • WHAT IS EFFICACY AND HOW DOES IT COMPARE TO THE COMPETITION?

    Efficacy is the amount of light produced compared with the amount of power required to produce it.
    This is measured in lumens per watt. Noribachi’s LEDs generally have an efficacy between 110-140 lumens/watt.

    For comparison with other directional light sources:

    • Mercury Vapor = 50 lumens/watt
    • Metal Halide = 80 lumens/watt
    • Fluorescent = 60 lumens/watt
    • Halogen = 10 lumens/watt
  • LED LIFECYCLE

    With a calculated life of an LED exceeding 100,000 hours, it is rather irrelevant to talk about a LED’s lifecycle. It will last “forever.”

    Every shift from analog to digital technology has had two consequences.

    Firstly, cheaper price and with it, more usage, and secondly much more rapid change.

    The shift from analog to digital in lighting will have the exact same consequences. Lighting will get much cheaper–especially on the high-end wattage and we will use much more of it. Every building will have wash lights, car dealerships will be brighter and municipalities will be more lit. The second consequence is that lighting that is bought today will be outdated in 3-5 years long before the life of the LED is over. It is the manufacturer’s duty to create a system that allows updates to the technology without needing to end the life of the product.

    Noribachi has, from the first day, had this tenet in its product design requirements. That is why we have the element of a Common Lighting Unit (CLU) that can be replaced and updated. We also have made everything in our lights modular so that one element can be updated and replaced without the need to completely replace the light. We also have instituted a program whereby we update our lights for a substantial discount after 3 years of service. This update will only require that the CLUs be updated and the power supply be reviewed.

  • WHAT IS USED ON LEDs TO MAKE THEM MORE WARMER OR YELLOW?

    Phosphorus controls the color of LEDs. The more phosphorous on the LED, the “warmer” the LED will look, but the less light it will give off. The phosphorus coating absorbs some photons resulting in less light illumination.

    The less phosphorus deposited on the LED, the “cooler” the LED will look, but the brighter it will appear.
