DARAY’s LED Examination and Surgical lighting range is the perfect choice for value and performance. Our LED lights have been developed to replace Halogen completely, saving you time, money – and importantly – diminishing your carbon footprint.

LEDs (light emitting diodes) have been around for a long time. Recently this technology has become leading-edge in the field of lighting – a breakthrough technological solution to the inherent problems of the incandescent light bulb. We have taken the technology and developed it further to provide high definition lighting solutions with no infrared, high brightness, low environmental impact, low power consumption, no toxic chemicals and a long operating life.

Here are the main benefits you can expect from switching your old Halogen lights to LED:

1. Long Lifespan

A core benefit of LED lighting is the lifespan of the LED bulb/module. With most of our lighting products, you can expect a life of approximately 50,000 hours. Let’s say the light is in use for 5 hours a day, that’s roughly 20-25 years of use from the LED light engine without ever needing to change the bulb – thereby reducing waste by 95% over the lifetime of the product.

2. Energy and Cost Efficiency

LED lights have an approximate energy efficiency of around 85-90%. This means that, of the total electrical energy used, 85% is used to actually produce light, with the remaining 15% being lost and converted into heat (still only producing a 2°c increase).

By comparison, a Halogen or an Incandescent light bulb has an efficiency of only 20% – meaning that a whopping 80% of the total electrical energy used is lost and converted into heat! Say if you were to have an electricity bill of £100 for lighting, then £80 of it was spent on lost energy. By making the switch to LED systems throughout, that same bill would sit at around £15 – saving you £85. Apply those maths to the average electrical bill for lighting only, for just one hospital, and you’re talking huge savings.

It’s not just the task lights such as the ones you use for Examinations and Surgery that you can switch, also consider all of the other types around you; Room lighting, reading lights, corridor lighting, car parks, headlights, streetlamps, etc. The more efficient you become on a larger scale, the more you can multiply those savings. Consider also, as discussed above, the savings made on the long lifespan of the bulb – further adding to the kitty and reducing wastage.

Consider for a moment, the extra funding available to a Hospital that has switched all of its lights to LED, and has therefore reduced its annual lighting bill by approximately 75-80%. Consider also what this money could be better spent on, perhaps towards providing much needed additional staff? Extra equipment? More efficient maintenance, and better quality of care for patients?

So, why waste it on producing unnecessary and harmful heat, gratuitous wastage and avoidable downtime.

3. Low Environmental Impact

LED lights, by nature, are free of all toxic chemicals. Most conventional lighting types commonly found in healthcare establishments, such a Fluorescent and Halogen bulbs contain a multitude of materials that are harmful to the environment, such as; Halogen, Mercury, Cadmium, Lead and CFCs

As well as containing no toxic chemicals, this type of light is also 100% recyclable – further helping you to reduce your carbon footprint by a huge leap. The long operational lifespan discussed in the above section means also that just one light converted to LED can save material and production of 25 equivalent incandescent, fluorescent or halogen bulbs. Here’s to a greener future!

4. Zero Heat in the Beam/Zero UV Emissions

Illumination by LED light produces absolutely no UV (Ultraviolet) emissions, and very little infrared light.

As a result, the very low radiated heat emission of LED lighting makes them highly suitable in a clinical environment, for illumination of both humans and animals, due to our UV-sensitive skin and delicate eyes.

5. Increased Visual Acuity

It remains a scientific fact that using LED lighting enhances your visual acuity – reducing eye strain among surgeons, headaches and fatigue. This works because an LED source delivers more ‘usable’ light to your retina, in part due to the high brightness and more natural Colour Temperature, essentially decreasing the amount of work that your eyes and brain have to do to distinguish one object from another. This helps contribute to, among other things, increased mental focus, faster responses, and reduced anxiety.

The superior Colour Rendering assists further, by allowing you to greater differentiate between tissue colours and tones. (see Colour Spectrum Explained)

6. Dispersal of Light

Our lights feature a strong beam of light with an even intensity across the entire area for clearer viewing and reduced eye strain. Halogen type lights, for example, make use of a mirrored reflector to help disperse the beam. These reflectors are covered with a dichroic filter, which can become stained over time with the high heat levels it is exposed to with constant use, thereby reducing the actual light output long before the bulb has reached the end of its life.

LED lighting, on the other hand, has no reflector and is designed to focus its light beam, achieving a much higher efficiency to the viewed area than other types of light. DARAY spend a lot of time on research and development of our lighting systems to ensure that they are able deliver the required amount of light to the subject far more efficiently.

7. Flexibility of Design

The lighting products in our range that are intended for Medical use, are designed with a circular light patch to match the intended clinical application on the human body. Our Dental lights produce a rectangular light patch, as required for Oral Surgery. This limits the emitted light to the mouth area only and away from the eye area, ensuring ultimate patient comfortability.

Some of our lights have a higher or lower fixed Colour Temperature than others (see Colour Temperature Explained within the Discovery Centre), and some with adjustable levels. All models (except for the X100 model) have variable intensity functions, for dimming the light.

We are able to do this because the technology behind LEDs allows for many different combinations of effect, enabling us to tune them to very specific levels for varying applications.

8. Safety

With a temperature raise on the surface of only 2°C, the risks of a patient or user burning themselves on a hot light bulb are entirely eradicated. All of our LED lights utilise a low voltage power supply, and the light fittings adhere to the anti-ligature requirements of the NHS.

Achieving 100% recyclable lighting within the UK’s Healthcare system is a lofty goal, however with a harsh environmental climate being realised far more so for future generations than our own, we all have a responsibility to reduce our environmental impact and adapt our procedures and equipment accordingly. The cost savings and efficiency increases seen when making The Switch, are simply added bonuses.

Our efforts to encourage LED solutions within the clinical workplace, and to provide further innovation within the lighting industry are making a big difference – one location at a time. That’s why DARAY are proud to be known as the UK’s most recognisable Medical Lighting manufacturer.
