LIGHTING MANAGEMENT SYSTEM

Whilst each light has its own benefits which we always consider:

  1. Lumens per watt for electrical efficiency
  2. Lumens to lux for lighting efficiency
  3. Watts per square meter for building electrical efficiency.

It is in the third point where we are particularly proud and focused on overall efficiency of the lighting which can only be realized by utilizing our built-in Lighting Management System (LMS).

We have selected Steinel as our sensor provider where accurate high-bay sensing is critical to both safe and efficient operations.

We offer the LMS in both a wired solution as well as wireless option and will take overall responsibility for the design, factory integration and on-site commissioning of the system.

Besides pure occupancy sensing, we can:

  • perform daylight harvesting which changes the function of the luminaire from a light source to only augmenting the lack of natural or other light sources.
  • Ensure consistent lux levels so that, no matter what is happening with weather or time of day, we can always ensure constant lux levels.
  • We can manage the upper consumption as well as minimum electrical consumption to ensure not only energy efficiency but also extend the life of the luminaire.

Technical Information

Explaining Watts, Lumens, Lux, CRI, Kelvin, and Binning

Clear definitions, simple targets, practical examples.

Watts

Watts measure power use, not brightness. Focus on lumens per watt for efficiency.

  • 400 W Metal Halide gives about 40,000 lm (100 lm/W)
  • 200 W LED gives about 36,000 lm (180 lm/W)
  • Same brightness, lower power

Lumens

Lumens measure total light output. More lumens means more light.

  • Office light about 3,000 lm
  • Warehouse high bay 20,000 lm or more
  • Streetlight 10,000 to 30,000 lm

Lux

Lux measures light on a surface, lumens per square metre.

  • Offices and classrooms 300–500 lx
  • Warehouse aisles 200–300 lx
  • Assembly areas 500–1,000 lx

We run lux simulations to meet targets before install.

CRI (Colour Rendering Index)

CRI shows how accurately colours appear, scale 0 to 100.

  • Below 60, poor colour accuracy
  • 80–90, natural and true colour
  • Our fittings, CRI above 80

Kelvin (Light Colour)

Kelvin measures colour temperature.

  • 2200 K, warm yellow
  • 4000 K, neutral white
  • 5000–6500 K, daylight white

Most products run at 5000 K for clear visibility.

Binning

Manufacturers sort LED chips by brightness and colour groups.

  • Consistent colour across fittings
  • Stable lumen output
  • Minimal colour shift over time

Quick Summary

Measurement Meaning Example or Target
Watts, W Power consumption 200 W LED replaces 400 W Metal Halide
Lumens, lm Total light output High bay 20,000 lm or more
Lux, lx Light on a surface Work areas 300–500 lx
CRI, % Colour accuracy Above 80 for industry and retail
Kelvin, K Light colour 5000 K daylight white
Binning LED quality and uniformity Tight binning for colour consistency
Understanding Light Performance

For engineers, buyers, and project teams who need reliable data and simple benchmarks.

Energy Efficiency

LED lighting converts electricity into light more efficiently than any legacy source.

  • LEDs produce up to 180 lumens per watt
  • Metal halide ~105 lm/W, Fluorescent ~95 lm/W
  • Less energy for the same brightness

Light Quality

High CRI LEDs reveal colour accurately and reduce eye strain in work areas.

  • CRI above 80 ensures true colour visibility
  • Daylight white (5000 K) for clarity in industrial zones
  • Better visibility increases safety and accuracy

Lighting Control Systems

Automation adds precision and reduces waste.

  • Occupancy sensors switch lights on only when needed
  • Daylight sensors dim output when sunlight is available
  • Scheduling and data logging built into LMS platforms

Maintenance and Lifespan

LEDs last up to 50,000 hours or more, with consistent performance.

  • Low heat output reduces component wear
  • Modular design allows easy repair or upgrade
  • Longer intervals between service cycles

Safety and Standards

All Pure Light products are tested, certified, and compliant with key lighting and electrical standards.

  • IES photometric data for every fitting
  • Compliant with SANS and IEC standards
  • Factory quality control ensures consistent build integrity

Return on Investment

Lighting upgrades typically pay for themselves through energy savings and reduced maintenance costs.

  • Average payback: 24–36 months
  • Ongoing energy savings up to 60%
  • Vendor-neutral calculations available on request
