Osram Halopin, eco, G9, 33w, Energy Saver



Osram is synonymous with high quality products and energy saving solutions. This 33w G9 mains halogen lamp replaces the standard 40w lamp and gives a 30% energy saving. The 48w G9 casule lamp has a colour temprature of 2,800 kelvins which is warm white and an average life time of 2,000 hours. The 33w lamp produces 460 lumens of light.

G9 halogen capsule lamps are small and enable the designer to put them in a variety of light fittings. They are instant start with a warm light tone. The beam angle of the light is determined by the design of the internal reflector within the luminaire.

Halogen lamps are friendlier at night time to local wildlife and insects as the light lamp colour is soft and warm at 2,800 kelvins, anything in the cooler colour spectrum 4,000 and above tends to disrupt nighttime patterns of wildlife especially bats and insects.


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 coulour 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‚Äôs 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 color scheme in mind and make sure to buy the bulb with a color temperature to match.

Light output ( Lumens )

The amount of light that is produced by a lamp is called lumens and the more lumens the lamp has the brighter it will be. Lumens 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 lumens and you then had another lamp which was a cool white 6,000 kelvins which also produced 300 lumens 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 ),  Lumens ( brightness) and contrast  ( colour of area )  The more lumens produced per watt the more energy efficient the lamp will be, for example you can have a 25w candle lamp that produces 170 lumens or a more energy efficient 18w candle lamp that produces 180 lumens so even though the wattage is smaller the lumens are greater which makes it use less electricity. That's what makes LED lights so energy effective as they can produce 700 lumens 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.
