Need to know how many lights to install in your room? Our Light Fixture Calculator helps you determine the optimal number of fixtures based on room size, usage, and lighting intensity (lux). Whether you're redesigning a bedroom, office, or showroom — this tool ensures you achieve the perfect lighting setup.
Lux (lx) is the unit of illuminance, measuring how much luminous flux is spread over a given area. One lux equals one lumen per square meter.
Common lux levels:
LED: Energy efficient, long lifespan (25,000-50,000 hours), wide range of color temperatures.
Fluorescent: More efficient than incandescent (10,000-20,000 hours), but contain mercury.
Incandescent: Inefficient (1,000 hours), warm light, being phased out in many countries.
Halogen: More efficient than incandescent (2,000-4,000 hours), bright white light.
General Lighting: Space fixtures evenly throughout the room for uniform illumination.
Task Lighting: Concentrate light where needed (e.g., kitchen counters, office desks).
Accent Lighting: Use directional fixtures to highlight architectural features or artwork.
Rule of Thumb: For ceiling fixtures, space them about the same distance apart as their mounting height from the floor.
