Free Hazloc Photometric Estimator

This 3D tool lets you quickly estimate fixture counts, placement, and expected illuminance for a classified space — directly from our catalog of explosion-proof C1D1, C1D2, and C2D1 fixtures. No download, no account required.

Read the mounting-height and lumen output guide before choosing a fixture.

How to use it

Set space dimensions (length, width, ceiling height).
Select the target hazloc classification (C1D1, C1D2, C2D1, or unclassified).
Pick the LEDEX fixture from the filtered list.
Visualize the 3D layout and illuminance levels instantly.
Export a PDF, or request a free sealed study for projects of 25+ fixtures.

When to use this tool

The estimator is ideal for: validating a layout idea before requesting a quote; quickly comparing two fixture models (e.g., TITAN C1D1 vs FORTRESS C1D2); giving specifying engineers a visual starting point. It is NOT a substitute for a sealed photometric study for code submissions or inspection approvals.

Sealed photometric study — free for qualifying projects

The online estimator is enough for preliminary planning. For commissioning, permitting, or code compliance with CEC section 18 / NFPA 33, you need a sealed photometric study (AGi32 or DIALux) signed by an engineer. LEDEX produces these at no cost for projects of 25 fixtures or more — including the AGi32 report, grid-based illuminance calculation, and optics recommendations. Submit your area classification drawing via the Contact page to get started.
