Stage 1 Initial discussion about the project, this will help us understand your requirements and get the idea of what you are hoping to achieve for your space. The more information given would be beneficial at this stage. An architectural plan and elevations to scale of at least 1:50 would be required for this. Otherwise a hand drawn plan but must include all the measurements, voids and ceiling heights. We would discuss furniture layouts here too. Stage 2: Detailed specifications and plans will be made based on the information given on stage 1. The plans will have specifications of lighting products and options based on 3 budgets whilst attempting to keep the same or similar light levels for the specific rooms. The budgets will include low, medium and high – you will be able to mix and match given the choice of fixtures. Stage 3: Whilst we will try and finalize everything by stage 2, it is never the case as site changes, furniture placement changes etc – we would accommodate by staying in touch with your electrical contractor or site manager to discuss any changes or provide any extra information that may require to complete the project to your specification. Minor adjustments in the plans, selection of the products would have to be finalized here. Site visits would be critical and are changes at £60.00 + VAT per hour. Stage 4: Once the first fix is complete the installer would require the second fix materials quite promptly. Here we would get the sales team involved to allow a smooth transition from the specification to the products. Each item will be ordered as per the specification to avoid any miss- calculations in products and returns. Any products returned will be subject to 25% handling fee. It is vital that a fully qualified electrician conducts the install as we cannot take responsibility for wrongly installed transformers/drivers. Stage 5: The final stage would be for us to make a final site visit, this visit ensures that all the fittings are installed as they should be, all in working order and program any lighting control units (if any) as per the initial specification. If a lighting control system has been used there will be another final visit once you have settled in. The final visit allows you to tweak any scene sets, button presses and finally engraving of buttons.    
LEDs are light emitting diodes. These are electronic components that convert electrical energy directly to light through the movement of electrons within the material of the diode. LEDs are important because due to their efficiency and low energy, they are beginning to replace most conventional light sources.
LED technology is constantly changing. Rapid innovation continues to improve the performance of LED on an almost daily basis. Future-proofing of LED modules allows luminaire manufacturers to switch from one generation to the next improved generation without major retooling or changes in luminaire design, offering backward compatibility with drivers.
LEDs are made of electronic components that need to be packaged together to offer long lasting efficient light sources to the end user. Apart from the LED chip itself which has sapphire and gallium in the semiconductor, the process of packaging with materials like ceramic, rare earth phosphors, silicone, solder and gold wire add to the overall cost. White LEDs require further tests for calibration and standardization.
Although the initial cost of conventional light sources is less than LEDs, the operational and maintenance costs of LED are significantly lower. LEDs, having a longer life, reduce maintenance and lamp replacement cost. . Because LEDs need to be replaced less frequently, the owner spends less on new lamps and the labor needed to change them. LEDs also consume less energy; thus the overall cost of a LED system can be significantly lower than that of conventional lighting systems. Most applications with LEDs offer a payback period as low as three to four years.
Lights built into wardrobes can be of the following types: • Low voltage LED lights with a magnetic switch that comes in two components; one is fixed onto the wardrobe door and the other to the wardrobe itself. When the door is opened the contact is broken and power is sent to the light. • PIR switches with an infra-red motion sensor that activates the light when the wardrobe is opened.
Most retrofits have the appearance of a conventional lamp and are used as direct replacement for the existing one. i.e. they have a screw or bayonet cap base. With downlights and spotlights, it's common to have a 50mm dia reflector lamp. The mains voltage ones are usually called GU10, which refers to the flattened pins on the base. However, some are available for 12V supply fed from a transformer, e.g. Direct replacements for 50mm dichroic LV downlights. These will have thinner pins and are often called MR16 or GU5.3 lamps.
As with complete LED luminaires, it is important to ask the supplier for the lumen output and to compare this with the unit you are replacing. If it is a spotlight, compare the two lamps side by side. Poor quality sales literature often states the output from the LED chip and not the complete lamp.
Retrofit lamps are offered with various white light outputs, ranging from warm to cool. This is often indicated on the packaging. Typically, it might say “2700K Warm White” or “4000K Cool White”. The bigger the number, the Cooler is the appearance.
LEDs are low voltage devices. Therefore, they require a device / Power supply unit / driver, or integrated electronics that convert line voltage to low voltage in order to run the LEDs. Sometimes The driver has electronics that can interpret control signals to dim LEDs.
The LED rating of a product is usually noted in milliamps, mA or volts, V. Products rated in mA can be used with a constant current driver, while those rated in volts can be run with a constant voltage driver. LEDs designed for constant current drivers cannot run with constant voltage drivers without damaging them.
LEDs driven by 24V drivers have longer permissible distances between light source and driver compared to 12V DC LEDs. 12V LEDs are usually suitable for applications where low light outputs are required. 24V LEDs offer products with higher outputs than 12V products.
This is usually due to incompatibility between the driver and the control system. When purchasing an LED product, it is important to use the correct driver type as specified by the manufacturer. It is also important to check that the LED is dimmable. Some retrofits are not.
50,000 hours would imply 5.7 years if the light is operated for 24 hours in a day, 7.6 years if the lights are on 18 hours per day and 11.4 years for 12 hours a day.
The thermal management of the LEDs. If LEDs come on a standalone chip, appropriate heat sinks have to be designed to prevent premature failure of LEDs. The electrical stress: Running LEDs at currents higher than specified make the LED run hot. This can happen with wrongly matched drivers. For example, if the driver produces 700mA but the LED needs 350mA, this will put stress on LED and reduce its lifespan. Higher ambient temperatures than the ones that the LED is rated for will reduce its expected life.
Typically, an LED will last four times longer than a CFL and 25 times longer than an incandescent source that puts out the same amount of light.
