DPA Lighting doesn't confine themselves to one lamp source - we supply all lamps types and take into consideration all lamp options when recommending the best lamp for your project:

• LED
• Induction
• IRC high output Halogen (energy efficient lighting)
• HID (Metal halide, High Pressure Sodium)
• Fluorescent T5 and T8
• Compact fluorescent
• Halogen

DPA Lighting can assist with retrofitting your existing building or supply an entire lighting package for your new project.

Energy Efficiency & Environmental Impact

Lighting can make a huge difference to the running and maintenance costs of a building. See below further information on what DPA Lighting can offer you:

Daylight Harvesting

Daylight harvesting is a simple principal to reduce your lighting running costs. As the sunlight increases, the electric lighting dims and reduces the energy consumed. These "daylight harvesting systems" are designed to maintain a nominated light level. This light level will vary according to the needs and use of the space. Ideally suited to offices fluorescent light or warehouse lighting.

Several studies have recorded the energy savings due to daylight harvesting. Energy savings for electric lighting in the range of 20-60% are common. Savings are very dependent on the type of space. Clearly, savings can only accrue in spaces with substantial daylight where electric lighting would have been otherwise used. Therefore daylight harvesting works best in spaces with access to conventional windows, skylights, light tubes or glass block walls etc.

At DPA lighting we offer a very user friendly system where the sensor-control gear is contained within the light fitting (depends on the light fitting selected). Using this system you won’t need smart wiring or expensive central control system. The benefits:

• They’re easy to install
• No additional wiring
• Each individual fitting will find its own light level rather than dimming in groups

They can also be installed into existing buildings without any rewiring.

Induction Lamps

Perhaps the most environmental lighting technology in the world, induction lamps are getting a closer look by the general public for its energy efficiency, long lifespan, and simply because it saves us from so much waste and garbage from any existing alternative light sources.

An induction light is similar to a fluorescent light in that a gas fill bulb is excited, emitting UV radiation that in turn is converted into visible white light by the phosphor coating on the bulb. Like fluorescent, the phosphor coating determines the color qualities of the light. Fluorescent lamps use electrodes to strike the arc and initiate the flow of current through the lamp, which excites the gas fill. Each time voltage is supplied by the ballast and the arc is struck, the electrodes degrade a little, eventually causing the lamp to fail. Induction lamps do not use electrodes. Instead of ballast, the system uses a high-frequency generator with a power coupler. The generator produces a radio frequency magnetic field to excite gas fill. With no electrodes, the lamp lasts longer. Some induction lamps can also be dimmed.

LED - Light-Emitting Diode

LED lamps are used for both general lighting and special purpose lighting. They come in multiple colors and are produced without the need for filters. This improves the energy efficiency over a white light source that generates all colors of light then discards some of the visible energy in a filter.

Compared to fluorescent bulbs, advantages claimed for LED light bulbs are that they do not contain mercury. Unlike compact fluorescent light bulbs, they turn on instantly, and that the lifetime is unaffected by cycling on and off, so that they are well suited for light fixtures where the bulbs are frequently turned on and off. LED light bulbs are also less apt to break.

LED have the reported characteristics of long life expectancy and relatively low energy consumption. The LED sources are compact, which gives flexibility in designing lighting fixtures and good control over the distribution of light with small reflectors or lenses. Due to the small size of LED, control of the spatial distribution of illumination is extremely flexible, and the light output and spatial distribution of a LED array can be controlled without efficiency loss.

LED lamps have no glass tubes to break, and their internal parts are rigidly supported, making them resistant to vibration and impact. With proper driver electronics design, an LED lamp can be made dimmable over a wide range.
