Big theo beam, mains 240v, G9 capsule lamp, 60w max, white, wall mounted, up and down light, IP44

The BIG THEO is a very modern style exterior up / down light designed for exterior use. Available in two colour options and constructed from aluminium.It has been designed with a small slot at the top and a wider slot at the bottom to produce an attractive light distribution. The upward light is a thin pencil beam which will project up to illuminate the underside of a soffit board and the downward light is for a wider distribution to illuminate the walkway or patio area.  This exterior wall light looks good fixed to entrance pillars and along the length of a property or either side of a garage entrance and will make your property stand out from the crowd.


A maximum of 60w G9 capsule lamp can be used which is 2,700 kelvins warm white and produces around 900 lumen's and has a average life span of 1,000 to 2,00 hours. G9 mains voltage capsules are very compact light sources. They use patented leading edge technology of filament support, which eliminates the disadvantages of the earlier bridge-type designs. LED lamp options in cool white or warm white are also now available to use in this fitting. LED offers energy savings and long life over the standard G9 mains halogen lamp.



Care must be taken when installing exterior lighting products especially those that are ground mounted. All the products are sold and tested fit for purpose and the IP rating is set according to the design and purpose of the luminaire, more details on IP ratings can be found under design ideas section. The weakest point is generally the installation of the product where adequate drainage has not been made for ground buried lights or poor cable joints have been made which are not 100% water tight and will allow for water penetration. There are a number of waterproof enclosures available on this site along with heat shrink cable joint kits and resin gel packs to fill the junction boxes to make a watertight enclosure. Where possible try and keep all joints and transformers above ground, however if this is not possible there are potted burial kits available.

Lamp colour ( Kelvins )

Lamp colour is determined by the Kelvins and a lamp which is  2700 kelvin  is classed as warm white and sympathetic to skin tones and warm brickwork. A kelvin of 6500k is in the  blueish white spectrum and works well against a white background and will appear brighter to the naked eye than the warm colour spectrum.


Light output ( Lumen's )

All lamps have a lumen number and the higher the lumen number the brighter the lamp, however colour of the lamp (kelvins ) also comes in to play here as a whiter lamp at 6,000 kelvins and above would always appear brighter to the naked eye than a warmer colour lamp at the 2,700 kelvins light spectrum even if it has the same lumen output.  A halogen 150w R7 lamp that is used in a standard garden security flood light would produce around 2,300 lumen's and a 26w compact fluorescent would produce around 1,800 lumen's.  Placing lights closer to the item to be illuminated is a good way of using a lower lumen lamp rather than trying to flood light a big area.

Environmental impact

Care should be taken for local wildlife, insects, and general light pollution,  this means the warmer colour spectrum ( 2, 700 kelvin )  does not interfere with insects and general wildlife as much as the blue spectrum ( 4,000 kelvin and above ). Cool white colours can disrupt insects and wildlife's  normal night time activity. This also applies to bats where a anti glare light fitting works better as well as reducing overall light pollution in the area.
