Lake black grill, HF control gear & Emergency, IP65, 28w 2D



Mains and Emergency  eyelid bulkhead fitting with additional front security grill.
The Lake is a low energy premium quality surface mounted bulkhead with a tough anti vandal main body and an eyelid to reduce light pollution and direct glare. It is suitable for both internal and external use and as a commercial or domestic applications and finished in the traditional textured  powder coat. The lake can be either ceiling or wall mounted.

High frequency control gear means instant start from the lamp and longer lamp life
The energy efficient 2D 4pin 28w lamp is included  and produces 2,050 lumens of light and even with the opal polycarbonate diffuser it is bright enough for stairways and a main source of building perimeter lighting.

It has integral maintained 3 hour emergency control gear.

Lamp colour ( Kelvins )

Lamp colour is determined by the Kelvins and a lamp which is  2,700 kelvins  is classed as warm white and is sympathetic to skin tones and warm brickwork. A lamp with a kelvin of 6500 is in the  cold blueish white spectrum and works well against a white background and will appear brighter to the naked eye than the warmer 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 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 neighbors 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
