Introduction: Due to today's high running cost it's important to evaluate old and exciting high consuming electrical light equipments compared to new technology with focus on low effect & low power consumption. Fluorescent lighting has been adopted in the majority of marine, business and industrial sites because of the increased efficiency compared to other lamps. Although this is a welcome step, a significant proportion of electricity consumption is still required for lighting. With the agreements between EU members and many other countries to reduce the levels of CO2 emissions by significant amounts, directives are in place to ensure that inefficient systems are phased out thus reducing energy generating requirements and hence emissions. There is scope to make these savings because all fluorescent tubes require a ballast to ensure that the necessary conditions are present to strike and sustain the lamp. In fluorescent lighting, conventional magnetic ballasts - the original designs are still most commonly found in existing installations - are inefficient. The poorest examples, class D types, have been banned in EU member states since 21/05/2002. Class C types, which limit input power to 70W when operating a 58W lamp, will be banned from 21/11/2005. Even the most energy efficient magnetic ballast, under the CELMA energy efficiency scheme, requires more input power than the rated power of the lamp driven at 50-60Hz. Other issues with magnetic ballasts are flicker, noise and lack of control. Flicker and noise occur because the lamp is being driven at the line frequency, 50Hz, which is on the edge of human sight perception and well within hearing range. The passive design prevents control such as dimming being used to further reduce energy consumption without resorting to expensive, external control equipment. In contrast, electronic ballasts enable large energy savings to be realised. This is primarily because they operate the tube at high frequency which is more efficient and allows equivalent light output with input power equal to or less than the tube rated power. Dimming can be implemented within the ballast, reacting automatically to ambient conditions or via operator interaction, to provide further savings. Reducing the energy consumed by lighting decreases the load on air conditioning systems giving additional indirect savings. Lamp flicker and audible noise are eliminated thus enhancing the working environment. The directives, with which ballasts sold in the EU must comply, also specify how effectively power must be consumed from the supply. The Power Factor (PF) is a measure of this effectiveness. It is the ratio of the actual load power to the apparent load power. A PF of less than 1.0 indicates increased losses in the supply system usually as a consequence of a phase difference between the applied voltage and the current drawn, a high harmonic content or a distorted/discontinuous current waveform. Electronic ballasts commonly include a Power Factor Correction controller (PFC) to maintain the PF within acceptable limits. However, the PFC circuit itself consumes power and is one of the remaining inefficiencies in the ballast-lamp system. Compact fluorescent lamps are being adopted increasingly by consumers keen to reduce their domestic energy costs. Many of the ballasts used to control these low wattage lamps claim compliance with the relevant EU directives whereas in reality they rely on an exemption clause for ballast-lamp combinations consuming less than 25W. The poor PF performance of these units is tolerated by the energy suppliers at present but one has to wonder how long this will continue to be the case when used in ever increasing numbers. The differences can be visualised by comparing voltage and current waveforms for different ballast types.

1.6 Summary According measurements, we found part of the installation with low power factor (Cos phi) especially in corridors, down lighters below 25Watt and dimmerable installations in restaurants and dining room. Low power factor (Cos Fi) will create high current (Amps) and reactive effect (VA) with result

• f low active and given effect (Watt).

Products with low power factor need more power to create the active effect. For calculation of ROI, we have used KWh as basic values. Upgrades to new technology will give a power factor up to 1 and the total savings will be higher than calculated in our report. Existing light installation undergoes a normal service and maintenance procedures with change of lamps, starters, capacitors, lamp holders and ballasts. The equipment is now 16 years old and a continuous change will therefore be necessary to keep everything upgraded for the best conditions. Mostly all checked light fixtures housing, are in a good condition and can easily be upgraded with new inserts as rep-kit. A total upgrade of 2482 light points according to this report for counting and calculations in different areas. We have not included any cabins or restaurants. Any changes in the remaining high energy consuming lamps as halogen and par20 must undergo a test installation before decision. Summary of existing lighting for replacement and upgrade:
