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 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? Efficacy is the amount of light produced compared with the amount of power required to produce it - measured in "lumens per watt" - and the higher the number the better! LEDs generally have an efficacy between 110-140 lumens/watt. By comparison, more traditional light sources just can't compare:
|LEDs||Mercury Vapor||Metal Halide||Fluorescent||Halogen|
|140 lumens/watt||50 lumens/watt||80 lumens/watt||60 lumens/watt||10 lumens/watt|
Every shift from analog to digital technology has had two consequences: first, cheaper prices and with it more usage, and second a much more rapid pace of continued 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The second consequence is that lighting that is bought today will be outdated in 3-5 years; long before the life of the actual LED is over.
With the calculated life of an LED exceeding 100,000 hours, it is irrelevant to talk about an LED's lifecycle. For all intents and purposes, it will last “forever.”
We believe that 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.
From the first day, we 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. Our lights are highly modular, which means that one element can be updated and replaced without the need to completely replace the entire fixture. In fact, we 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
The days of LEDs being "harsh" are long over. In fact, LEDs have the benefit of offering a wide spectrum of light running from bright "cool" white to a much warmer, "soft" white suitable for any occassion. How does it work?
Phosphorus controls the color of LEDs; the more phosphorous on the LED, the "warmer" the LED will look. But, because the phosphorus coating absorbs some of the photons, lights that appear warmer also give less illumination. The less phosphorus deposited on the LED, the “cooler” the LED will look, but the brighter it will appear.
