🏠 The Problem Most People Face
Many homeowners spend a lot of money on fancy décor but ignore lighting — and later feel their rooms still look dull, uncomfortable, or unbalanced.
Most people buy lights only by wattage or looks, without understanding brightness (Lux), color temperature (CCT), or CRI.
The result?
- Rooms are either too bright or too dim.
- Wall colors look different or dull.
- The space feels uncomfortable for the eyes.
If you’re planning to buy LED lights for your home but don’t know what to choose — this simple guide will help you understand everything:
👉 how to measure your room area, what brightness (lux) level to choose, how to pick color temperature (CCT), CRI, wattage, and how LEDs can save your money every month.
🌟 Why Good Lighting Is Important
Light changes everything — how you see, feel, and live.
A good lighting plan can:
-
Make your home look bigger and more beautiful.
-
Improve mood and comfort.
-
Reduce eye strain while working or reading.
-
Save up to 80% energy compared to old bulbs.
Lighting is not just decoration — it’s part of your lifestyle and health.
🔹 Step 1: Measure the Room Area
Every light plan starts with room size. The larger the area, the more brightness you need.
Formula:Area = Length × Width
Example: 12 ft × 12 ft = 144 sq. ft.
Each area type needs a specific Lux level (lumens per square meter):
| Room Type | Recommended Lux | Lighting Purpose |
|---|---|---|
| Living Room | 250–300 Lux | General brightness |
| Kitchen | 35000–450 Lux | Work and cooking |
| Bedroom | 150–200 Lux | Relaxed mood |
| Bathroom | 250–300 Lux | Grooming & function |
| Study Room | 500–600 Lux | Reading & focus |

🔹 Step 2: Choose the Right Color Temperature (CCT)
CCT (Correlated Color Temperature) defines how “warm” or “cool” your light appears.
| Type | CCT (Kelvin) | Feel | Where to Use |
|---|---|---|---|
| Warm White | 2700K–3000K | Cozy & soft | Bedroom, Living room |
| Neutral White | 4000K | Natural & balanced | Kitchen, Dining |
| Cool White | 6000K–6500K | Bright & focused | Bathroom, Study |
👉 Tip: Warm light helps you relax; cool light helps you stay alert.

🔹 Step 3: Check CRI (Color Rendering Index)
CRI shows how accurately a light displays color.
- Range: 0–100
- Home use: CRI 80+
- Premium areas (showroom, makeup zone): CRI 90+
High CRI makes walls, furniture, and clothes look true to life.

🔹 Step 4: Understand Wattage and Efficiency
Brightness depends on lumens, not just wattage.
Always check “lumens per watt” — higher means better efficiency.
| LED Wattage | Lumens (approx.) | Replaces Old Bulb |
|---|---|---|
| 5W | 450 lm | 40W bulb |
| 9W | 900 lm | 75W bulb |
| 15W | 1500 lm | 100W bulb |
⚡ Tip: Choose energy-efficient LEDs — they reduce heat and power use.

🔹 Step 5: Plan Lights According to Room Use
| Room | Suggested Light | CCT | CRI |
|---|---|---|---|
| Living Room | Ceiling panel + cove strip | 3000K | 80+ |
| Bedroom | Warm bedside or wall lights | 2700K | 80+ |
| Kitchen | Bright downlights | 4000–6000K | 85+ |
| Bathroom | Mirror + ceiling LED | 6000K | 85+ |
| Balcony | IP65 waterproof LED | 6000K | 80+ |

🔹 Step 6: See How LEDs Save You Money
LEDs use up to 80% less electricity than old bulbs.
Example:
Replacing 100W bulb with 15W LED →
Savings: 85W per hour × 4 hrs/day = ~₹500 saved per year (per bulb).
LEDs last 25,000–50,000 hours = 5–10 years of use.
So, you spend once and save for years.
