How are LEDs evolving and impacting businesses?
There are now high quality LED luminaires for street, area and landscape lighting; down lighting; track lighting; shelf and display lighting; decorative fixtures; 2X2 and 2X4 recessed luminaires for general ambient light; even high brightness high bay luminaires. The directional nature of LED tree sources allows for more of the lumens generated to be emitted from the luminaire compared to traditional light sources making these luminaires extremely efficient. The advancements in LED technology has lead to higher efficacy and higher lumen LED chips, as well as chip on board technology minimizing or eliminating heating sinking requirements, enabling the development of luminaires for general ambient lighting that deliver more than 100 lumens per watt. Most indoor luminaires typically have a rated life of 50,000 hours (L70), but there are many street and area lighting luminaires with life ratings in the 70,000 to 100,000 hours range. Color consistency fixture-to-fixture and color stability over life is being address with “hot binning” of LED chips or the incorporation of intelligent active color control into the LED system to maintain the color within a two-step or three-step Macadam color ellipse minimizing perceptual color differences. There are also a variety of phase cut, 0-10 V, DALI and wireless lighting controls that have been developed for dimming of LED lamps and luminaires down to 5 to 20 percent.
The advancements in LED technology and more reasonable price points for LED luminaires definitely makes LED cherry tree solutions worth looking at. Remember, not all LED solutions are alike and requires doing your homework. Before deciding on an LED solution, it is best to install a few luminaires and evaluate its performance before making a final decision.
