Common questions

How do I start a plan?

Open the Rooms tab and create a room with its width, length and ceiling height, or open the sample room to look around first. Then open the plan editor and add ceiling lights, wall lamps, floor lamps or LED strips.

Why does the estimate change when I change the room finish?

The room finish sets the utilisation factor, the share of the lamps’ light that reaches the working plane. Light, medium and dark finishes use different defaults, and you can set your own value. The defaults are simplifying assumptions, not measured values.

The circles on the plan do not look like my real lights. Is that wrong?

The dashed lit areas are notional. They are drawn from each light’s beam angle and height as a picture of coverage; real luminaires have no hard edge. The circles are not used in the lux estimate.

The estimate is below the range. What now?

The ranges are indicative general guidance for homes, not a standard, so treat them as a starting point. You can add or change lights, try another layout of the same room and compare the two. The figure is one average for the whole room; it does not tell you how the light is distributed.

Where does the yearly running cost come from?

From the total power of the layout, the hours per day and days per year you enter, and the unit rate you type in from your own bill or tariff. The app has no built-in prices, and standing charges are not included. Without a unit rate only kWh is shown.

How do I send the plan to my electrician?

Open the room, choose Export and share the PDF project sheet, the image of the plan or the CSV luminaire list through the Android share sheet, or print it. The export contains no wiring, circuit or cable information.

Can I move my rooms to another phone?

Not in this version. Your rooms are stored only on the phone, there is no account or cloud copy, and the app’s data is excluded from Android cloud backup. An export is a copy for reading and sharing, not a backup that can be loaded back in.

How do I delete my data?

Delete single rooms and layouts in the app, or everything at once with Settings → Delete all data. Uninstalling the app removes its data too. We hold no copy, so we cannot restore or delete anything for you.

Can you tell me whether my lighting is safe or whether the work must be notified?

No. The app plans where lights go and gives no wiring or installation guidance. A qualified electrician must check the technical safety of the installation, and will tell you what applies to your project.
