SALEH DECO LIGHTING TOOLS
Lighting Calculators & Planning Tools
Plan Your Lighting with Greater Confidence
Use practical lighting calculators developed by Saleh Deco to estimate light levels, understand beam spread, plan fixture layouts, size chandeliers and pendants, configure modular lighting, and calculate LED strip power requirements.
Designed for homeowners, architects, interior designers, contractors, and lighting professionals.
CHOOSE YOUR TOOL
Start with the Question You Need to Answer
Each calculator focuses on a different lighting decision. Start with the question you need to solve, then combine the relevant tools when your project requires more detailed planning.
Plan the Lighting
Lux & Lumens Calculator
How much light does this space need?
Estimate room lumens and approximate fixture quantity using area, target lux, utilisation, maintenance and the selected fixture’s light output.
Spotlight Layout Calculator
How should the spotlights be arranged?
Plan grid, perimeter, L-shaped or parallel-row spotlight layouts using room dimensions, spacing, beam angle, fixture output and target lux.
Beam Angle & Light Spread Calculator
How wide will the light beam be?
Calculate approximate beam diameter from mounting distance and beam angle, then compare narrow and wide coverage for objects, surfaces and task areas.
Size & Configure
Chandelier & Pendant Size Calculator
What size chandelier or pendant should I choose?
Estimate suitable chandelier or pendant proportions for rooms, dining tables, kitchen islands, foyers, double-height spaces and multi-pendant arrangements.
LED Strip Driver & Cable Calculator
What driver and cable setup does the LED strip require?
Calculate LED strip load, driver capacity, system current, cable voltage drop and practical feed requirements for 12V, 24V or 48V installations.
Modular Lighting Planner
How should I configure a modular lighting system?
Build a preliminary modular-lighting system using track lengths, corners, connectors, power feeds and compatible lighting modules.
Compare & Specify
LED Lighting Cost & Energy Savings Calculator
How much energy and money could an LED upgrade save?
Compare existing and proposed lighting to estimate energy use, electricity cost, maintenance, annual savings, payback, ROI and NPV.
Light Quality & Visual Comfort Selector
Which light-quality requirements suit your space?
Choose suitable CCT, CRI, R9, SDCM, flicker and glare-control requirements, or compare a product’s declared lighting performance.
Follow the Lighting-Planning Sequence
Not every project needs every calculator. Use the tools that apply to the type of lighting you are planning.
1. Determine the Light Required
Start with the Lux & Lumens Calculator to estimate how much light the room needs and the approximate fixture output or quantity required.
2. Understand the Beam
For directional lighting, use the Beam Angle & Light Spread Calculator to see how mounting distance and beam angle affect the approximate illuminated area.
3. Arrange the Fixtures
Use the Spotlight Layout Calculator to translate the lighting requirement into a practical ceiling arrangement with spacing, wall offsets, beam coverage, and optional lumen validation.
4. Size Decorative Fixtures
Use the Chandelier & Pendant Size Calculator to relate suspended fixture size to dining tables, kitchen islands, room dimensions, foyers, and other spaces.
5. Plan Modular Systems
Use the Modular Lighting Planner when the project uses compatible track sections, connectors, power feeds, and interchangeable lighting modules.
6. Size the Power System
For LED strip installations, use the LED Strip Driver & Cable Calculator to calculate connected load, driver capacity, current, cable voltage drop, and feed requirements.
7. Compare Energy and Operating Cost
Compare existing and proposed lighting systems to estimate annual energy consumption, operating cost, maintenance, savings and project payback.
8. Define Light-Quality Requirements
Choose suitable CCT, CRI, R9, SDCM, flicker and glare-control requirements, or compare declared product performance.
Use each tool independently for one decision, or combine the relevant calculators to build a more complete preliminary lighting plan.

PRACTICAL, NOT GENERIC
Clear Inputs. Useful Planning Outputs.
Each tool converts practical project information into clearer calculations, visual guidance, and more informed product decisions.
Guided Inputs
Plain-language fields help users enter the dimensions and technical information relevant to each calculation.
Transparent Calculations
Important assumptions, sizing references, and calculation methods are shown so users can understand how the result was reached.
Visual Planning
Where appropriate, layouts and diagrams help explain spacing, coverage, scale, and arrangement rather than presenting only a number.
Product-Aware Decisions
Selected tools can connect calculation results with Saleh Deco product information to help users move from planning toward suitable real products.
Preliminary Guidance, Not a Final Lighting Design
Saleh Deco’s calculators provide practical preliminary estimates based on the information entered and the calculation method used by each tool.
Actual results can vary according to the selected product, photometric distribution, room reflectance, ceiling height, furniture, architectural features, installation conditions, control system, and other project-specific factors.
Decorative fixture sizing should also consider visual weight, sightlines, circulation, ceiling height, fixture body height, and suspension length.
For complex, high-ceiling, commercial, specification-critical, or technically demanding projects, calculations should be reviewed using the selected products and complete project information.
The tools do not replace a full photometric study, electrical design, structural assessment, manufacturer instructions, or site-specific technical review.
