Room lighting planner

Estimate the fixtures to compare.

Use your chosen brightness target and fixture output for a rough ambient lighting plan.

A starting point for ambient light

Choose a brightness target in lux and enter the lumen output printed on your fixture. RangVault converts floor area to square metres and estimates a fixture count. Beam spread, daylight, surfaces and room height still matter.

Example prices only: ₹350/L and ₹12/sq ft are sample inputs, not current market prices. Replace with your local quote. 100 sq ft per litre per coat is an editable example. Use the coverage on your paint tin. Painter rate is applied once to wall area; confirm what your quote includes.

Range is illustrative; brand, product and surface can differ greatly. Excludes repairs, taxes and other materials. Ceiling, primer and putty are included only when selected.

How we calculate

Wall area = 2 × (length + width) × height − doors/windows, summed across rooms. Area across coats = painted area × coats. Paint litres = area across coats ÷ your coverage, then 10% extra and rounded up. We use whole litres to suggest common 1 L, 4 L, 10 L and 20 L tins. Ceiling is length × width per room when selected. Primer and putty use their own editable coverage and prices.

This is a planning estimate. Ceiling, primer and putty are off by default. Repairs, tax, delivery, surface preparation and extra materials are excluded.

Colour code is a digital HEX reference, not a paint brand shade code. Match a physical swatch before buying.
