About this app

DO YOU DESIGN LIGHTING SYSTEMS, ARE YOU AN INSTALLER, OR A DIY ENTHUSIAST?
"Lighting Calculations" is the ultimate tool that transforms your smartphone into your best ally for lighting projects.

Forget complex manual calculations and the risk of design errors. With our app, you will have a complete ecosystem of calculators, converters, and tables right at your fingertips, designed to save you precious time on-site or in the studio. Lighting design will no longer hold any secrets!

WHAT CAN YOU DO WITH OUR APP?

ADVANCED CALCULATIONS AND DESIGN:
• Ambient Design: Calculate total luminous flux, the required number of luminaires, illuminance, and surface uniformity.
• LED Analysis: LED lifespan (L, B, and C parameters), photobiological risk, and calculations for LED strip power supplies.
• Efficiency: Luminous efficacy calculation, lamp energy savings, and power factor correction.
• Integrated Tools: Digital lux meter for quick field measurements and photometric code decoding.

QUICK AND PRECISE CONVERSIONS:
• Lumens / Lux / Candelas / Watts (in all possible combinations).
• Lux / Foot-Candles (for international standards).
• Quick power comparison across different lighting technologies.
• Luminance and Illuminance / Exposure Value (EV).
• Color Temperature (Kelvin) to RGB conversion.

RESOURCES, TABLES, AND UPDATED STANDARDS:
• Regulatory requirements: Required lighting levels for indoor environments.
• Technical guides: Lamp types, bases, bulb shapes, and fluorescent tubes.
• Lighting quality: Kruithof diagram, visible spectrum, color temperature, and Color Rendering Index (CRI).
• Safety & Classification: New energy labels, Unified Glare Rating (UGR) scale, symbols, and units of measurement.
• LED Focus: Typical characteristics and specifications of SMD LEDs.

EXCLUSIVE BONUS:
Inside, you will find a highly useful COMPLETE FORMULARY with all the mathematical formulas for lighting engineering at your fingertips, along with generic tables for 220V lamp power factor correction.

WHO IS THIS APP FOR?
Engineers, architects, lighting designers, electricians, students, and anyone who wants to achieve perfect, well-calibrated lighting that complies with industry standards.

The lighting quantity is supposed to mean how many nos of the same light would I need to achieve the lux level desired. But the option does not even require you to put dimensions and the qty is always 1? Would that not be an error or did I misunderstand your description?

Good but more details are needed, fluorescent lights are nowoutdated , remove their calculation and replace with LED Lights data. Beam Angles like 24,36,60,120 degrees should be incorporated in app.
