💡 Lighting Calculator

Getting the right lighting for your room can transform a space — but knowing how many light fixtures you need can be tricky. Too few lights, and your room feels dark and gloomy. Too many, and you've wasted money on unnecessary fixtures and higher electricity bills. Our Lighting Calculator helps you find the perfect balance.

Whether you're planning a kitchen renovation, a living room makeover, or a garden office, this calculator works out exactly how many lumens you need and how many light fixtures to buy based on your room size and the purpose of the space.

What our lighting calculator does:

📏 Room Size — Enter length and width to calculate the area.
💡 Room Type — Choose from kitchen, living room, bedroom, bathroom, office, or garage.
📊 Lumens Required — We calculate the total lumens needed for your space.
💡 Fixture Count — Based on your chosen fixture type (LED, fluorescent, incandescent).

💡 Pro Tip: Different rooms need different light levels. Kitchens and offices need the brightest light (300-500 lux), while bedrooms and living rooms can be more ambient (100-200 lux). Use our calculator to plan your lighting project with confidence.
