The remodel problem
A centered plan is only useful if the cans can actually fit.
Existing framing can turn a clean lighting grid into field changes, uneven spacing, and avoidable patching. Light Layout Pro helps you think through those conflicts while the layout is still easy to change.
The app works from the dimensions you provide. It models likely conflicts; it does not see through finished ceilings or confirm concealed conditions.
A practical workflow
Measure. Model. Adjust. Share.
Model the ceiling
Add measured framing, can diameter, safety buffer, and ceiling items with their sizes, positions, and coordination clearances.
Resolve the conflicts
Compare centered layouts, see modeled clashes, and fine-tune fixture positions before work begins.
Share the plan
Keep layouts on your iPhone and share a result as text or an image when you are ready.
Precision Layout
Start centered. Then account for the ceiling.
Set the room, target light count, layout style, wall offsets, and framing measurements. Compare automatic suggestions or move fixtures with spread and whole-layout shift when the real room calls for it. Add measured HVAC registers, return grilles, access panels, speakers, detectors, or other rectangular and round ceiling items.
- Centered grids and configurable rows
- Joist or truss direction, spacing, and offset
- Can diameter and safety-buffer inputs
- Ceiling-item sizes, positions, and coordination clearances
- Modeled clash and spacing feedback
Inside the app
Built to stay useful in the field.
Clear choices, measured inputs, and visual plans—without accounts, advertising, or tracking.
Hallway / Linear
Equal spacing for straight, narrow runs.
Plan a single row of fixtures along a hallway or corridor centerline, beginning from a defined wall offset and checking the run against the framing you enter.
Six free field tools
From the bend to the tape.
Bend geometry, tape-measure fractions, electrical math, and your own bender values—available without a subscription or account.
01
Offsets & saddles
Bend Calculator
Solve offsets plus three-point and four-point saddles with plain bend geometry.02
Rise & roll
Rolling Offset
Combine rise and roll into the true travel and bend spacing for one rolling layout.03
Large-radius sweeps
Segmented Bends
Plan equal bend shots and tape-ready marks from the radius and total angle you enter.04
Your bender’s numbers
Bender Profile
Keep your own take-up, gain, and deduction values together for repeatable field arithmetic.05
Tape-measure math
Fraction Calculator
Add, subtract, multiply, and divide feet, inches, and tape-ready fractions.06
Ohm’s law & power
Electrical Math
Solve single-phase volts, amps, ohms, watts, VA, power factor, and VAR from entered values.The field tools use geometry, arithmetic, or physics from the values you enter. Verify results against your bender, materials, plans, job specifications, and applicable local requirements.
