Pema, exterior surface LED wall light, Mains 240v, 3.3w, warm white, 3,000 kelvin, 145 lumen's, IP44


The Pema comes in three colour finishes. Code 231012 Silver Grey with 120 lumens, Code 231015 Anthracite with 110 lumens and code 231010 white with 120 lumens.
A very modern contemporary styled small yet powerful 3.3w LED puck light. Total consumption 4.2w. Ideal for low level illumination or on a wall to illuminate a house number or steps. A clean simple design with a very low energy consumption. Water resistant IP44. Very low glare rating due to the recessed lamp and shield from the luminaire housing.  

LED luminaires run very cool and therefore safe to touch, they also use very low power consumption to save on electricity bills and also have a long life span. And if you use a mains 240v  LED luminaire there will be no need for a transformer which can sometimes be awkward to hide.       

One disadvantage to using a mains 240v luminaire rather than a low voltage one is when the luminaires fails you will have to throw the whole fitting in the bin and buy a new one and if they no longer sell that product you will need to replace all the units. Another disadvantage to using mains 240v in the garden is the danger of cutting through the cable. A 12v supply is a lot safer for exterior installations.

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 

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.

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
