It has been right three times already during recent years that the company Philips attracted attention releasing two new T8 lamps and one additional gadget. The first one was simply a compatible retrofit solution with a lower power rating for luminaires equipped with both magnetic or electronic ballasts – but which prove to be not quite as simple as that.

The properties of LED lighting

Wed, 03/20/2013 - 18:56

Incandescent lamps are cheap but tend to have short lifetimes. The light emitted by incandescent sources is perceived as particularly pleasant because these hot radiators generate a continuous (or full) emission spectrum. Nevertheless, as hot radiators they waste much of the electrical energy supplied to them.

Are Distributed OLED Light Sources Poised to Change Home Lighting?

Wed, 02/15/2012 - 15:06

Since before the invention of the incandescent light bulb, lighting in the home has been accomplished by the use of point light sources. As candlelight and gas lamps transitioned to electrical lighting, room light sources continued to be localized, either as light fixtures in the ceiling, or as lamps or accent lighting located for specific uses like reading or security lighting.

Options for automated lighting systems In single rooms

A complete retrofit of an existing home to incorporate smart technologies for energy management and home automation can sometimes be overwhelming to homeowners, both in terms of cost and complexity. Because the energy and time savings from utilizing such systems can be significant, it is worth looking at lower cost solutions.

LED Residential Lighting

Wed, 05/04/2011 - 10:00

The most recent addition to the array of residential lighting options is LED-based lighting. An LED, or light emitting diode, is a semiconductor-based device that emits light due to the change in energy of electrons in the semiconductor material as a result of an input voltage.

Under-counter Lighting in the Kitchen – Attractive, Practical, and Energy Efficient

Wed, 04/27/2011 - 17:03

A modern trend in home building and remodeling is to place lighting on the underside of kitchen cabinets. Typically, under-counter lighting is considered to be task lighting, because it is intended to provide adequate illumination for tasks that are performed on kitchen countertops.

Dimmer Switches for Compact Fluorescent Light: Overcoming a Major Obstacle

Wed, 04/20/2011 - 16:26

One of the issues with compact fluorescent lighting (CFL) is the lack of ability to use CFL bulbs with conventional dimmer switches. Dimmer switches allow users to have a greater amount of control over ambient lighting in residential environments.

Compact Fluorescent Bulbs

Wed, 04/13/2011 - 15:46

Home lighting is one area where energy usage can be greatly reduced. The conventional light bulb used in residential applications has traditionally been the incandescent bulb. Incandescent bulbs and halogen bulbs emit light from a heated filament, meaning that most of the energy used by these bulbs is emitted in the form of heat. Hence, incandescent bulbs are inherently inefficient light sources.

Simple Steps for Reducing Energy Costs in Home Lighting

Wed, 04/06/2011 - 14:19

Conserving energy when it comes to residential lighting is becoming easier with new technologies and products on the market. Today’s energy-savvy homeowner can implement several simple steps to reduce the use of energy associated with home illumination. Many of these suggestions will be featured in future articles.

American commerce trends toward more efficient lighting

There is much focus on energy efficiency in residential applications, but the commercial sector is working to conserve energy, as well. And as with a home, owners and managers of commercial buildings are looking to lighting as an area of opportunity for more efficient energy consumption.

However, the Commercial Buildings Energy Consumption Survey, conducted by the United States Department of Energy, revealed some critical information about the commercial sector.

A new year... and a new life for incandescent lamps

This is not a light bulb...

Incandescent light bulbs are often criticized for having a luminous efficiency of only 5%. However, flip-flop your perception and you have a device with a heating efficiency of 95%. Change the name from 'light bulb' into 'heatball', and same device transmogrifies from efficiency Class F to efficiency Class A.

The knowledge acquired during the course should be sufficient for:

Garden and terrace lighting

Guy Kasier

Fri, 11/12/2010 - 08:54

In many contemporary homes, the garden occupies a more central place in our home life. All kinds of grasses, plants, flowers, shrubs, trees and water features provide an oasis of calm in a natural environment. If there is enough space, benches, tables and chairs are placed here and there, slightly hidden from the rest of the garden to provide a brief escape from the stresses of daily life.

LED lamps ... and their claims!

Fri, 09/03/2010 - 08:42

In a press release, the manufacturer claims that this LED lamp 'imitates the behaviour of an incandescent halogen lamp and hence will not cause any problems when replacing incandescent halogen lamps with it'.

LED lamps ... and fans and noises

LED lamps, electronic converters and ...

Wed, 09/01/2010 - 15:11

Electronic transformers or converters for 12 V halogen lighting raise many a claim over conventional transformers made from lots of iron and copper. One is that the output voltage is regulated and hence offsets variances of the load. Variances of input voltage, they do not balance out, but this they do not claim. So much as an aside.

Eco-friendly Off Grid lighting for developing countries

On Lake Victoria in Kenya OSRAM has launched a unique project for producing light away from a permanent power supply. At a specially constructed solar station (OSRAM Energy Hub) the local people can recharge batteries for energy-saving lamps, luminaires and other electrical appliances, such as mobile phones, at low cost and without damaging the environment. Off Grid solutions are the way forward for developing and emerging countries that cannot afford to set up a permanent power supply network. The market is huge.
