Specification Tools
Professional calculators and visualization utilities designed to accelerate your engineering workflow and bridge the gap between initial spatial conceptualization and formal photometric modeling.
Available Tools
Interactive calculators to establish preliminary specifications.
Lumen Method Calculator
Estimate preliminary fixture quantities using the Zonal Cavity Method. Includes localized presets for Singapore SS 531 compliance and dynamic Lighting Power Density (LPD) checks against BCA Green Mark 2021 Super Low Energy thresholds.
Beam Spread Visualizer
An interactive, bi-directional calculator to visualize geometric light spread. Input mounting height and beam angle to determine the resulting diameter, ensuring perfect optical selection for architectural accents and retail displays.
LED Strip Voltage Drop
Prevent color-shift and dimming in architectural linear lighting. Calculate exact DC wire decay across 12V, 24V, and 48V systems based on standard copper resistivity and AWG wire gauges.
Downlight Spacing (SHR)
Generate optimal fixture grid layouts using Spacing to Height Ratios (SHR). Guarantee visual uniformity ($U_0$) and completely eliminate dark zones in your architectural lighting layouts.
DALI vs Casambi Selector
Navigate the most debated topic in modern lighting control. Utilize our interactive decision tree—evaluating project scale, IEC 62386-202 emergency lighting compliance, and BMS integration needs—to determine the optimal control topology for your project.
Frequently Asked Questions
What lighting specification tools does Illum-Tec offer?
We offer a suite of professional B2B engineering tools including a Lumen Method Calculator localized for Singapore SS 531 standards, an interactive Beam Spread Visualizer, a DALI vs Casambi Selector, and an LED Strip Voltage Drop Calculator.
Are these calculators substitutes for DIALux modeling?
No. Our digital tools are designed for rapid, preliminary estimations and budgeting. For regulatory compliance and formal photometric specification, comprehensive 3D simulation via DIALux or Relux is strictly required.
Are the tools free to use?
Yes, our digital engineering tools are provided freely as a resource to empower architects, interior designers, and M&E engineers in Singapore to make informed preliminary lighting decisions.
Need a formal lighting layout?
Calculators provide an excellent starting point, but true specification requires precision engineering. Illum-Tec provides formal Dialux reports, IES file processing, and exact driver compatibility checking (DALI / Casambi) for trade professionals in Singapore.
