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.


Lamp details

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.

Installation guide


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 rubber round double insulated cable can be used for low voltage installations ( NOT PVC ). 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‚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 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)
