Progress in the LED Sector
Are LED’s Becoming More Versatile?
My last blog focused on ways to eliminate the amount of energy consumed by interior and exterior lighting. You may recall one of the tips was to replace inefficient fixtures/lamps with those rated as high efficiency.
There’s no question that Light-Emitting Diodes (LED’s) are the most efficient light source available on the market today. Unfortunately, based on a significantly higher initial capital cost basis compared to most conventional lighting technologies, many people continue to opt for the less expensive option despite the documented energy savings potential.
Good news! LED lighting firm Lemnis Lighting has launched three lines of its Pharox LED bulbs, including the new 200-lumen Pharox BLU which costs under $5. The three Pharox 350 lumen bulbs will use 6.5 times less energy per annum than its typical 40-watt incandescent counterpart, and in most cases, has a simple payback of less than two years.
The Department of Energy predicts that the price of LED lamps and packages will drop by about 30 percent each year until 2015 and 10-15 percent per year for the following 5 years. Similar to Lemnis Lighting, smart energy products firm Noribachi streamlined pricing of its LED lighting resulting in reductions of up to 31 percent across its product line.
Another shortcoming of LED’s had been the limited availability of technologies as potential lighting alternatives for all fixtures. It seems like each quarter, new technologies are being launched to address and resolve this issue. Example: many industrial facilities – warehouses, manufacturing facilities, and cold storage applications – use high bay fixtures to illuminate the space. Inefficient technologies such as metal halide and high pressure sodium lamps were typically the preferred choice because more effective options didn’t exist.
Dialight has just unveiled a 17,000 lumen LED High Bay luminaire designed for a wide range of industrial lighting applications. The units operate on an integrated universal power supply enabling uncomplicated replacement of conventional sources such as metal halide and high pressure sodium fixtures. This model nicely compliments Dialight’s existing low bay model typically used for lower ceiling height applications, such as parking garages and cold storage facilities.
Until now LED’s have been overlooked as a viable option to replace inefficient lighting technologies due to cost and availability. Lighting firms have responded to this outcry, and have been taking strides to develop technologies capable of replacing a broader range of existing fixtures at a more attractive price point; so don’t rule out LED’s when tackling your next lighting project.
