💡 Lighting Lumens Calculator – Calculate Light Output for Any Room | EarnApki
🔦 What Is a Lighting Lumens Calculator?
The Lighting Lumens Calculator on EarnApki.com is a free online tool that helps you estimate the total light output (in lumens) required for any space—whether it’s a home, office, garage, classroom, or warehouse.
It takes into account room area, purpose, and brightness levels to calculate the ideal amount of lumens (light output) needed for optimal visibility, comfort, and energy efficiency.
💡 What Are Lumens?
Lumens (lm) measure the total amount of visible light emitted by a light source. Unlike watts (which measure energy consumption), lumens reflect the actual brightness of a bulb or fixture.
| Light Output (Lumens) | Comparable to |
|---|---|
| 450 lm | 40W bulb |
| 800 lm | 60W bulb |
| 1600 lm | 100W bulb |
More lumens = brighter light. The Lighting Lumens Calculator helps you get just the right amount—not too dim, not too harsh.
🛠 How to Use the Lumens Calculator
- Enter the room size in square feet or meters
- Select the room type (e.g., bedroom, kitchen, office)
- Choose desired brightness level (dim, standard, bright)
- Click Calculate Lumens
- Instantly get the recommended lumen output
🏠 Typical Lumen Recommendations by Room Type
| Room Type | Suggested Lumens/sq.ft. |
|---|---|
| Bedroom | 10–20 lumens |
| Kitchen | 70–100 lumens |
| Living Room | 20–30 lumens |
| Bathroom | 70–80 lumens |
| Office/Study | 50–75 lumens |
| Garage | 80–100 lumens |
This tool helps you plan how many and what type of bulbs or fixtures to use.
📦 Example Calculation
Let’s say your living room is 200 sq ft. and you want standard brightness:
- Suggested lumens per sq ft. = 25
- Total lumens = 200 × 25 = 5,000 lumens
So you’ll need a combination of bulbs or fixtures that provide at least 5,000 lumens of light in total.
