Myra, adjustable single lamp head, mains 240v GU10, IP44
The myra is a group of light fittings made in Germany. The group includes a single
spot wall lamps and up / down wall lights, this enables you to have a consistent
theme to your outdoor lighting. SEE SPIKE OPTIONS AT BOTTOM OF PAGE.
The Myra single head adjustable light fitting is a multi purpose exterior luminaire.
Finished in silver grey with a slim shaft and offset adjustable mains GU10 lamps
it can have a bottom section that is spiked to place it in soft grass areas or the
bottom section can be a surface mounted base plate to bolt directly to a level concrete
area. Each lamp head can be rotated and aimed at specific areas like a seating area
and a walkway. The mains GU10 LED lamp is cool to touch and safe around children.
The main head unit can be taller with the extension piece which in turn must have
either the fixed base unit or the end spike unit. Connection lead length 3m.
All exterior lighting must be installed by a NIC EIC certified electrical contractor
that has experience of exterior lighting installations. All joint need to be 100%
watertight by using a heat shrink cable joint kit and waterproof junction boxes.
Energy efficient lamps
Choosing the right lamp is a combination of 3 main factors, Lumen's, Kelvins and
efficiency. There are other factors but not so relevant for exterior lighting products.
Efficiency matters because you want the maximum light out put possible ( Lumen's
) from the minimum amounts of watts consumed. The latest LED technology and compact
fluorescent lamps are amongst the most efficient you can buy today. An example would
be to change a mains halogen GU10 35w lamp to a ECO friendly GU10 5w LED lamp. The
same be done by changing the older GLS light bulb for a compact fluorescent lamp.
Reduced energy bills with no loss of light output helps the environment and reduce
your energy bills.
LED energy saving example
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 ( 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
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 )
Installation
Choosing the style of a product is only part of the equation you must also think
of where that product will be used and how it will be installed. All exterior lighting
products on our web site have a IP rating which is explained further in our design
ideas section but in simple terms the IP rating is appropriate to each light fitting
and its intended application and is therefore fit for purpose. Water ingress is the
enemy for outdoor lighting and the products supplied are only as good as the installation
as the weakest point is always cable and transformer joints. All joint must be made
100% water tight and this can be done using heat shrink kits, waterproof junction
boxes which are then filled with a resin mix. All joints where possible should be
made above ground for easy access and reduced water ingress. When installing ground
buried lights adequate drainage systems should be put in place especially in clay
based soil areas. If possible use ground surface spike lights rather than a buried
light. Mains 240v cable will have less joint than a low voltage installation
but care must be taken with the cable runs.
Environmental impact
Care should be taken for the environment and local wildlife to maintain the ecological
balance. Insects, bats, wildlife can all be effected by light pollution. The
warmer colour spectrum of ( 2,700 Kelvins ) does not interfere with insects
and general wildlife as much as the blue colour spectrum of light around 6,000 kelvins
which can disrupt their normal night time activity. This also applies to bats where
a anti glare light fittings works better as well as reducing the overall light pollution
in the area. You must also be mindful of your neighbours and the effect your lighting
can have on them and shining a 500w tungsten halogen flood light in to their windows
at night will cause them distress. Try to keep the light in a downward position and
local to the items you want to illuminate and even if you want to illuminate tall
trees it can be done in a sympathetic way by placing a ground buried or surface spike
flood light directly under the trees to illuminate the canopy. Some light fittings
also have a anti glare shield fitted to reduce light pollution.
IP Rating
All the luminaries on our web site have been specifically designed fit for purpose
and assigned a relevant IP rating which denotes the amount of protection that is
required from water and dust. More information on IP ratings can be found in the
design ideas section on this web site.
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.
Average levels of illuminance in Lux
Sunny June day 80000 Lux
Bad light stopped play at Lords 1000 Lux
A well lit office 500 Lux
Main road lighting 15 Lux
A residential side street 5 Lux
A clear moonlit night 0.2 Lux
