Big theo, up and down light, Mains 240v 9w GX53, white, IP44
The Theo and big Theo are part of a wider range of wall mounted fittings coming
in a number of sizes and lamp choices.
The glass is frosted at the edge while the major part is clear to create an attractive
halo effect. The BIG THEO uses a GX53 9w energy saving lamp that creates a wide beam
of up and down light. Place 3 in a row for a lighting effect or singular either side
of an entrance.Traditional bow style wall light that would suit many types of properties.
When installed around eye level there is next to no glare from the lamp source.
The GX53 lamp is low on energy and has a long life to help reduce maintenance cost's.
The 9w produces around 300 Lumen's and is available in 2,00 kelvin warm white or a
cool white version. Lamp life is around 6,000 hours. There is also a LED lamp option
available and only uses 4.2w, this lamp has a more directional beam angle of 35 degree
where as the standard non LED lamp throws light in a very wide beam spread.
Lamp type comparison
First and foremost all new external electrical works must be installed by a PART
P registered electrical contractor. The contractor must supply you with full certification
once the work is completed. For mains 240v supply SWA ( steel wired armour
) cable is highly recommended and
round double insulated cable can be used for low voltage installations (
). Each supply should also be on its own RCD. Cable should be buried to a safe depth
to avoid any unnecessary risk due to garden forks or spades. Equally as important
and probably the weakest link in any exterior cable run is the joining of cables.
Each joint will need to be 100% water tight and this can be achieved by the use of
Magic Gel poured in to junction boxes once the termination is complete
or heat shrink kits as per FIG 1 and FIG 2 below. Where possible try and keep all
low voltage transformers and joint boxes above ground, this will reduce the risk
of water ingress.
Lamp colour ( Kelvin's )
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
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 the area)
