LED Lighting FAQ
What is an LED?
An LED, or Light Emitting Diode, is a two-lead semiconductor light source. When these leads receive adequate voltage, photon energy is released in an effect called electroluminescence. While they have been around in a practical application since the early 1960’s, only within the past decade have developments in the technology made them a viable and cost effective solution for landscape lighting and other wide use capacities.
What are the advantages of LED bulbs?
LEDs have numerous advantages to include the following:
- Lower energy consumption of up to 80% means monetary savings which add up over time
- Longer lifetime of up to 50,000 hrs per bulb can extend to decades of lamp life
- Increased sturdiness provides critical outdoor durability
- Smaller size creates more fixture flexibility and variety
- Faster switching creates near instantaneous turn on time
How do LEDs differ from halogen bulbs?
Low voltage halogen bulbs last from 2,000 to 5,000 hours compared to LEDs that can range from 30,000 to 50,000 hours. In terms of energy usage, a 35watt halogen bulb is equivalent to a 4 watt LED bulb. Monetarily, low voltage halogen bulbs can typically save up to 20% in energy costs whereas LEDs can yield savings up to 80%. LED bulb price averages about $30 per lamp more expensive though technology and production advances are gradually driving the cost down.
What determines the color of an LED?
LED light output covers a spectrum ranging from whites and cooler blues (4000K+ temperatures) to warmer yellows & oranges (sub 3000K temperatures). Color is dictated by the wavelength of the light emitted but can be manipulated by colored lenses. Newer technology also allows for a variety of options with beam spread as well as lumen output (level of brightness). Bottom line: there are loads of great design possibilities!
Can any existing lighting system be retrofitted to LED lighting?
The short answer is yes! The industry is flooded with outdated lighting systems that can greatly benefit from an overhaul. See our LED Retrofitting page to learn more.
Do LEDs require maintenance?
To keep your lighting system in optimal working order, fixtures containing LEDs should receive annual maintenance. See our Lighting Maintenance page to get a better idea of how to keep your system in top working order or to learn how Nightscapes can help you out.
Are LEDs truly "fail proof"?
As with most products, even the highest quality LED can still fail. Fortunately, most are subject to manufacturers’ warranties ranging anywhere from 3 to 15 years. Nightscapes also warranties our labor for a period of 2 years to be free of defects and operate as intended.
