220px-RBG-LEDLED (Light Emitting Diode) Lighting has become the standard in energy efficient lighting projects.

There are many reasons LED's are the most effective technology currently employed in the energy savings industries, from safety, energy and consumption to durability and non direct operation.

Basic Lighting Technology

Without getting too technical for the non electrical engineers, let use some information from EnergyStar.gov:

Incandescent bulbs produce light using electricity to heat a metal filament until it becomes “white” hot or is said to incandesce. As a result, incandescent bulbs release 90% of their energy as heat. These are the classic, Edison inspired bulbs from the 1800's, and represent the least efficient technology due to excess heat and inefficient conversion of energy to light.

Fluorescent (and compact fluorescent (CFL) bulbs use an electric current flowing between electrodes at each end of a tube containing gases. This reaction produces ultraviolet (UV) light and heat. The UV light is transformed into visible light when it strikes a phosphor coating on the inside of the bulb. This is "lighting 2.0", and once running can consume 70% less energy than the older incandescent bulbs.

LED (Light–Emitting Diodes) bulbs, are semiconductor devices that produce visible light when an electrical current passed through them. Think "lighting 3.0". LEDs are a type of Solid State Lighting (SSL), as are organic light–emitting diodes (OLEDs) and light–emitting polymers (LEPs).LED,_5mm,_green_(en).svg

Why are LED lighting systems better?

The main focus is energy consumption, however there are other very important concepts such as safety, durability, environmental friendliness etc...

  • Energy Consumption: The top metric for LED superiority is energy efficiency. In general, LED bulbs use 5%-10% of the comparable incandescent lighting energy. The most obvious way to understand it is heat. Both Incandescent and Fluorescent technologies create light as essentially a byproduct of HEAT, while LED systems generate light directly.
  • Heat control: By producing significantly less heat,there is far less demand on secondary systems (Air Conditioning for example). This is an additional level of efficiency, and in some cases create MORE SAVINGS than the actual cost of the energy consumed by the bulbs themselves.
  • Safety: Fluorescent lights (especially CFL) contain toxic chemicals (primarily mercury) that are potent neuro-toxins.
  • Longevity: LED bulbs last 2-4 times longer than Fluorescent bulbs, and 35-45 times longer then Incandescent. For commercial, industrial, and retail operations the maintenance and replacement costs are significantly lower.
  • Usability: Most Fluorescent bulbs are not dimmable, creating problems in application

Going beyond changing light bulbs

Before you run out and just start changing bulbs, get a professional, free consultation

While changing a light bulb out for another type does have savings, there is a critical difference in approach when it comes to true energy efficiency projects. If you are trying to qualify for special programs like On-Bill Financing, trying to get ADA compliant, working with retrofitting non standard lighting systems, or have stringent building codes and site specific requirements, you need an experienced partner. Many systems sold are actually just residential bulbs that don't take into consideration the unique requirements of many retail, commercial, and industrial needs.

It is not uncommon for Ecogreen Solutions to take on a project that was mishandled by previous contractors. We have been asked to take over projects where lack of product knowledge, poor management, lack of in field experience, and even shady business practices resulted ins erious problems for the customer. Because of the press and incentive programs offered, many contractors added energy effeciency to their services, and plunged right in to projects they had no business doing.


Our Consulting, Design, Project Management, Fabrication, Installation, and Warranty services deliver CLEAN, GREEN, EFFICIENT, COMPLIANT energy strategies. Your project is far more than "replacing light bulbs".

Our focus is Turn-Key, Full Service, Maximum ROI projects.
