A question we often get asked is - How do your change an LED light? There are a number of possible answers to this: 1) You don't - an LED light is manufactured as an integrated component, with a life often in exces of 50,000 hours the liklihood is that a full refurbishment will occur long before the 'lamp' needs replacing. 2) If one is REALLY keen to change the light, then a professional could remove the phosphor chip and replace it. Although the practicality and economics of doing so make this a rather doubtful excercise. 3) Some common lamp types such as GU10's can simply be replaced with an LED retrofit 'bulb' When replacing your lights we would recommend that, as with most things, you get what you pay for, and cheap fittings will fail sooner, or worse, will change colour to one that you weren't planning for, like yellow or green. If ever in doubt contact us for, at the very least, some guidance and advice.
Lighting technology has evolved significantly in recent years and LED lighting now supersedes any previous lighting technology in terms of energy efficiency. LED lighting also has a much longer life than older technology meaning that the fittings don't require changing as often. If you have anything other than LED lighting currently installed, it is highly likely that you can make a financial saving in your energy bills and maintenance costs through updating your lighting to LED technology. Additionally, lighting legislation has changed, ensuring that your lighting is illuminating the target spaces to the correct lighting level will ensure that you're not over-lighting a space, which could be costing extra to run and maintain. We can survey your existing lighting technology and take readings to measure the amount of light being produced, from which we can calculate how much energy you could save.
Getting lighting control right is important for the energy efficiency of a lighting scheme and there are many options available. Light fittings can be programmed to switch off or dim down if there are periods of time in which the space is absent of people, this can reduce electricity use by 30%. If natural light is available within a space then daylight controls can be introduced to reduce the amount of light output required from the artificial lighting, this can reduce electricity use by 40%. We can measure the amount of daylight contribution within your space, and assess the potential of space usage controls to advise if this method of control would be financially beneficial to your lighting scheme.
There are a number of funding and grant options available dependant upon the type of organisation, which can include cash neutral third party funding. There are also both local and national incentives available to support business in transition from energy intensive to energy efficient technology as well as the opportunities through Enhanced Capital allowance rebates. We will always investigate these options for you as part of our solution development.
Even if the building is not owned by your organisation updating the lighting usually be of benefit to you in terms of electricity use, not to mention wellbeing. This depends on how much longer you plan to use the building for and long it will take for your new scheme to pay for itself. As LED has become much more efficient as well as costing less, through our Solution Development we can calculate how quickly the Return on Investment your new lighting scheme may be. Usually if you intend to occupy the building for three years or more then you'll realise a financially benefit from updating to LED lighting.
You could. There are many excellent products available on the internet at very sensible prices, in fact, there are thousands. What system will you use to ensure that the products that you buy will be appropriate for the activities being carried out at the point of use? Are compliant with European and British Lighting Legislation? Carry an appropriate warranty? Have the desired colour render index and light distribution? Getting the lighting design right is important for the energy efficiency and the wellbeing of users. For example, to achieve a comparable lighting level you may not require as many lights now due to the enhanced light distribution of modern products, only a simulated lighting design can truly calculate this. Furthermore, the British Standards have re-specified many lighting requirements, such as the colour to which an object or person is rendered. Gaining design advice from a lighting professional will ensure your new lighting scheme is energy efficient, and in compliance with current lighting standards. Emergency lighting legislation also needs to be compliant with modern standards. Replacing emergency fixtures on a like-for-like basis it is unlikely to satisfy the legal standards. Our lighting simulated design will provide assurance that the required lighting levels are attained
This will depend on the use of the space and the type of lighting that is currently installed. The older the technology and the higher the hours of use the more you are likely to save. Recent lighting-only projects have saved in excess of 60%, whilst projects with lighting and lighting controls have achieved savings in excess of 70%.
Wellbeing is becoming a popular topic and lighting can significantly influence how building users feel. The correct light levels, glare rating and quality of light, usually in terms of colour, can positively impact the alertness and accuracy of those subject to it. Furthermore, research has shown that simulating the changing colour of daylight throughout a 24 hour cycle, known as Circadian Lighting, can improve patient recovery time as well as improve the concentration of pupils in learning environments. Through our solution development we can produce a lighting design that is bespoke to your organisations needs.
A light fittings (or any electrical component) IP rating relates to its Ingress Protection rating. The ratings are usually represented as 'IP44' or 'IP54' dependent on its ability to withstand ingress. The first number refers to the fittings protection against solid materials, whilst the second number refers to the protection against liquids. 11 - Protected against solid objects over 50mm and water falling vertically. 22 - Protected against solid objects over 12mm and direct sprays from up to 15 degrees from vertical. 33 - Protected against solid objects over 2.5mm and direct sprays up to 60 degrees from vertical. 44 - Protected against solid objects over 1mm and sprays from all directions. 55 - Protected against dust and low pressure jets of water from all directions. 66 - Totally protected against all dust and strong jets of water. 67 - Protected against temporary affects of immersion between 15cm & 1m for 30 minutes. 68 - Protected against long periods of immersion under pressure.
