Benefits of LEDs
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
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?
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
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
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second consequence is that lighting that is bought today will be outdated in 3-5 years long before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.
LED Color Warmth
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
