Delwa curve, wall light, silver grey, 2 x 4w LED, neutral white 4,000 kelvin, 325 lumen's, IP44



Very modern, stylish, contemporary soft curved LED wall mounted up / down light in silver grey finish. The Delwa Curve has built in powerful 4 x1 w LED lamps top and bottom to produce a cool white medium beam distribution. Very low energy consumed and ECO friendly due to the long life expected from the latest in LED technology using twin luxeon LED lamps. There is also an integral driver unit so all you need do is wire it straight to a mains 240v supply. Due to the design of the luminaire there is minimal glare produced. The curved body makes this up down light a little more unique than the standard straight barrel types available.

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 ( 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 area )

 

Installation

Please ensure that you use a PART P, NIC EIC electrical contractor for your exterior lighting installations and also check the dimensions of the luminaire before purchasing.

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 local wildlife, insects, and general light pollution,  this means the warmer colour spectrum does not interfere with insects and general wildlife as much as the blue 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 overall light pollution in the area.
