5.3w Integral GU10 lamp, 36 Degree beam angle, Cool White 5000k, 420 Lumens, Non Dimmable

LED GU10s are a great way to save energy and money. The Integral 5.3w LED GU10 consumes a lot less power than the halogen spot light equivalent (35W). It also has a much longer lifespan, on average lasting as long as 25,000 hours. This results in decreased maintenence costs with the need to replace being far less frequent. This retro fit LED GU10 is a direct replacement for standard halogen lamps unlike many other GU10s which are generally a lot larger.

Lamp colour ( Kelvins )

The colour of a lamp is defined as a measurement called kelvins. A standard GLS light bulb in your house would be 2,700 kelvins which is in the warm colour spectrum and a lamp with 6,000 kelvins would be at the very cold white spectrum. Getting the right colour temperature of a lamp does matter as the warm colour wavelength helps to soften skin tones and gives a warm soft relaxed feel and at the other end of the scale a 4,000 to 6,000 kelvin lamp colour would be used in offices or a fast food restaurants to make you feel less comfortable and relaxed and more alert. There’s nothing that can sour your opinion of a compact fluorescent or LED lamp like buying a 4000K or 5000K bulb when you meant to buy a 2700K bulb, or vice-versa. When you buy a new, energy efficient bulb, keep your application and colour scheme in mind and make sure to buy the bulb with a colour temperature to match.

Light output ( Lumen's )

The amount of light that is produced by a lamp is called lumen's and the more lumen's the lamp has the brighter it will be. Lumen's work in conjunction with kelvins and watts should not be taken in isolation of each other, for example if you had a very warm white lamp at 2,700 kelvins and it produced 300 lumen's and you then had another lamp which was a cool white 6,000 kelvins which also produced 300 lumen's the cooler lamp colour would always appear brighter to the naked eye than the warmer one this is due to the receptors in the eye that react better to a white light spectrum. Another factor on how bright a light may appear is contrast so if you shine a white 6,000 kelvin light on to a dark wall and a warm 2,700 kelvin lamp on to a white wall the warmer lamp would appear brighter due to the contrast of the material it is focused on. So when choosing a lamp always take in to account the area you want to illuminate and think about Kelvins ( colour ), Lumen's ( brightness) and contrast ( colour of area ) The more lumen's produced per watt the more energy efficient the lamp will be, for example you can have a 25w candle lamp that produces 170 lumen's or a more energy efficient 18w candle lamp that produces 180 lumen's so even though the wattage is smaller the lumen's are greater which makes it use less electricity. That's what makes LED lights so energy effective as they can produce 700 lumen's from a 5w lamp.

Light intensity or Light levels ( LUX )

Light levels are measured in something called LUX. Put simply LUX is a measurement of light falling on a given surface area. For example an average LUX of 200 would be needed for an outdoor tennis court for recreational purposes and a side street walkway would have an average of 5 LUX. To calculate lux levels you need a very good calculator or computer as there is a number of factors that need to be taken in to account.Lux levels can be effected by a beam angle of a lamp, for example if you had a 50w 38 degree MR16 halogen lamp at 3 mtrs from the floor and another 50w 10 degree MR16 lamp placed next to it, the one with the 10 degree beam angle would record a higher lux level due to the concentrated light in a small area so you could drop the 50w lamp to a 35w lamp to save energy and still achieve the desired light level.

The same wattage lamp ( 50w ) has been used in each of the examples above and the only change is the beam angle of the lamp which raises the intensity ( Lux ) levels on the floor.
