Industrial lighting design isn't just about picking an appropriate wattage or hanging more powerful LED fixtures. The lighting system has to be designed to nsumpdeliver the necessary light, uniformity, and reliability with control of energy cotion and installation cost.
Many small design factors can affect the overall economics of a project, including lens selection, lumen efficiency, quantities, mounting height, spacing, conduit routing, etc. Industries can optimise these parameters together to reduce not only the connected lighting load but also the number of lighting fixtures and cable and conduit requirements, while maintaining the required lighting performance.
About Pyrotech Technologies
Pyrotech Technologies is an industrial lighting manufacturer and supplier providing LED lighting solutions for industries and demanding applications. Its portfolio includes industrial, outdoor, AC/DC and flameproof LED lighting solutions designed for different operating environments and application requirements.
Lighting Calculation – Optimise Fixture Quantity
The basic parameters of the design in industrial lighting. The larger the fixture, the more light it does NOT necessarily provide. The fixtures and their locations will depend on the area being illuminated, the height of the fixtures above the pool, the desired level of illumination, the distribution of the beams, and the operating conditions.
When doing calculations, they can also avoid overlighting and underlighting. Insufficient fixtures can lead to reduced visibility and dark areas that pose safety risks, while too many fixtures can lead to higher connected load, product costs, cable needs and installation costs. Accurate planning thus facilitates the provision of safe, efficient, uniform and cost-effective industrial lighting.
Installation and maintenance accessibility
Optimum Lens Selection – More Light Where It Is Required
Just because it is a HIGHTEMP LED fixture, it is not necessarily an efficient lighting design. If the beam angle or optical distribution is not adequate for the application, a considerable amount of light can be sent outside of the required working area.
This can result in:
Choosing the right lens and beam distribution will help the light that is available to be more directed towards the desired area.
When choosing a lens, you need to take into account:
Key idea: Optimise the optical design, rather than increasing fixture wattage to address poor light distribution.
Higher lm/W – More Light from Every Watt
Lumen efficiency is the number of lumens generated per watt of the luminaire, and is expressed as lumens per watt (lm/W).
For instance, two LED luminaires could deliver the same illumination but have different wattages. If both lighting performances are similar and one of them offers a greater useful lumen output per watt, it can contribute to lower connected lighting load.
Why lm/W matters:
However, lm/W should not be considered in isolation. Actual lighting performance, optical distribution, uniformity, thermal performance, application conditions and required illumination should also be evaluated.
Lighting Calculation – Optimise Fixture Quantity
A lighting calculation helps determine how many fixtures are actually required and where they should be positioned.
Instead of selecting fixture quantities based only on assumptions or previous projects, the design can be evaluated using the relevant site parameters.
Important parameters include:
A simple design format can be represented as:
Mounting Height + Spacing + Lens Distribution + Lumen Output + Reflectance + Maintenance Factor → Optimized Lighting Layout
Why this matters
An unnecessarily high number of fixtures can increase:
A properly engineered layout aims to achieve the required illumination without unnecessary fixture quantity.
Shortest Practical Conduit Routing – Reduce Installation Cost
Lighting optimisation should not end after calculating lux levels.
The physical arrangement of fixtures, junction boxes, cable trays, panels and electrical distribution points can also influence project installation costs.
The Problem
A lighting design may achieve the required illumination but still require:
The Possible Solution
Coordinate the lighting layout with the electrical installation layout.
The objective should be to achieve the required lighting coverage while keeping cable and conduit routes short, practical and maintainable.
This makes lighting design a broader electrical engineering exercise rather than only a lux calculation activity.
Problem: Focusing Only on Fixture Purchase Price.
A lower-priced LED fixture does not necessarily produce the lowest overall project cost.
A fixture with a lower purchase price could require:
Possible Solution: Look at Total Project Economics
Instead of comparing only the price per fixture, consider:
Fixture Cost + Fixture Quantity + Connected Load + Cable + Conduit + Installation + Energy Consumption
This provides a more complete basis for evaluating an industrial lighting solution.
One Plant Example – Standard vs Optimised Design.
Consider a simplified plant lighting requirement.
Standard Design
100 × 60 W = 6 kW connected lighting load
Optimized Design
80 × 45 W = 3.6 kW connected lighting load
Difference
6 kW − 3.6 kW = 2.4 kW reduction in connected lighting load
This example shows how a combination of fixture quantity optimisation and lower power, appropriately selected luminaires can reduce connected load.
This should be treated as an illustrative design example. Actual fixture quantity and wattage must be determined from the project's required lux level, mounting height, optics, operating environment, maintenance factor and other design parameters.

These projects demonstrate our commitment to optimizing power consumption, reducing energy costs, and providing long-term operational efficiency across industrial facilities.
1. How can smart industrial lighting design help to save energy in the following ways?
The wattage, lumen efficiency, number of fixtures, optical distribution and lighting layout of the fixtures can all be optimised to reduce energy consumption used in industrial lighting. The goal is to get the desired light without the need for an unnecessary connected load.
2. What factors should you consider when choosing LED lenses?
The lens determines the light distribution coming from the luminaire. The correct beam angle can output more light to the target work area, increase uniformity and may even eliminate the need for other fixtures.
3. Will lighting calculations allow fewer fixtures to be used?
Yes, proper engineering of the lighting calculation can help to establish a proper number of fixtures by various criteria, including these such as various mounting heights, spacing, lumens output, and required illumination. The goal should be to achieve the optimum amount, rather than the minimum amount.
4. What are the ways of reducing installation costs of industrial lighting design?
The locations of fixtures, positions of junction boxes, the lengths of cables, and the route of the conduit can affect installation costs. Planning the lighting layout in conjunction with the electrical distribution system can reduce lengths and make more efficient pathways.
