Because there are so many possibilities, Linear LED is made to measure for you. Of course there is an experienced sales person who can assist you but to simplify matters we have created this LED LAB section to explain some of the basic concepts of lighting and how to light with Linear LED.

Our showrooms at Province Lighting in Cape Town and Johannesburg and our brochure are all designed to break it down into these basic decisions to ensure you get the best result:


      1. What LED profile to choose.
      2. What colour temperature to choose.
      3. What intensity of light to choose.


The type of lighting effect you are wanting to achieve is going to answer these questions for you. This image of our showroom displays the available option with indirect bulkhead lighting and recessed, surface and suspended fittings.




The smaller profiles ( LF5, LFtab, LF45, LF18 ) are used for indirect lighting in bulkheads. Using high output LED in bulkheads is also becoming popular as the primary lighting in upmarket residential.


Also for task lighting under counters, in cabinetry and in shop fitting when the light source must be hidden.


The bigger profiles ( LF35’S, LF50’S & LFSTAIR ) can be ordered as fittings or custom lengths and patterns (and can be mounted surface, recessed or suspended. Combined with a high intensity LED this is suitable for primary lighting and has higher output, better efficiency and better light quality than fluorescent and halogen down lighters.




The colour temperature of light is measured on the Kelvin scale, usually between3000K to 5000K. The lower the colour temperature, the warmer the colour of the light, the higher, the cooler:


  • 3000K – WARM WHITE, the colour of filament light bulbs or sunrise.
  • 4000K NATURAL WHITE, nice comfortable and contemporary in between.
  • 5000K COOL WHITE, cool and clinical.
  • Warm white is used for domestic applications where the colours in the house are warm and rich like reds and browns. It’s brings out the warmth in wood and stone.


Natural white is very popular and used in commercial applications like shopping malls and shop fitting and in contemporary housing design where the lighting enhances the architecture.

Cool white is used in crisp, clean enviroment where very clear lighting is needed. And also used in outdoor and signage applications as it works best with the waterproofing resin.




LED technology has advanced noticeably in the last few years and so has the brightness. Linear LED is no longer just suitable for task and effect lighting but can be used as primary lighting too. Our LED range (link) is named according to its lumen per meter output from EB200 (200 lumens per meter) to EB3500 (3500 lumens per meter). To give that some perspective, a 50watt halogen down lighter puts out 650 lumens and a standard 4 foot fluorescent tube puts out 2850 lumen.


The lower output LEDs are used for signage, task lighting and effect lighting. The middle of the range is mostly used for bulkhead (indirect) lighting and the top of the range is used for primary lighting and shop fitting.


When ordering the LED you would choose the intensity and the colour temperature. For example: EB1100NW.




One way to do it is to give the measurement of the space the LED is going into and we will make it to the closest size. Otherwise the easy way to measure up for LED is using the standard lengths table (link). Once you have chosen what LED you are using, measure the space where it is going. Then go to the standard lengths for that type of LED. The size less than or equal to (<=xmm) your measurement is the one you want. (measuring of LED and standard sizes).


LED cannot be cut just anywhere, it works in sections and can only be cut between these sections. These cut points can be from 62.5mm to 167mm apart. Most commonly 100mm. But that is why you need to know what type of LED you are using when you measure up. It is best to have 50mm to 100mm gap to the wall either end of the LED in any case. Don’t make it too close to the wall because you will get a hotspot of light against the wall.


We have to put end caps and cable on the LED extrusion too, so if you have a measurement of 400mm, we have to add 25mm for end caps and cable. So the closest piece of LED to fit into a 400mm space would be 325mm.




The electrical energy the Linear LED uses is measured in Watts per meter. So we use this measurement of Watts p/m for that type of LED (summary table) to determine the power supply needed. So for example: If you have 5 meters of EB400 (5 watts per meter) you would need a 25 watt power supply.


The voltage of the LED must match the output voltage of the power supply.

Never connect LED direct to mains voltage (220V), it will burn out the electronic components instantly.


Observe the polarity of the DC supply to the LED. If the polarity is reversed, it won’t work. Try avoid getting the polarity wrong as some types of LEDs can be damaged by reverse polarity.

LED Laboratory

Linear LED has opened up the creative potential of lighting. We can now blend lighting seamlessly with architecture. It can be slightly more technically challenging than choosing a regular light fitting but the possibilities of what can be done and the results speak for themselves. And it is also energy efficient and maintenance free.
