Let’s talk about lighting. Not the sexy-before-and-after Instagram kind (though yes, that too), but the kind that quietly controls your mood, sleep, energy, productivity… and sometimes your patience level by 3pm.
If you’ve ever wondered why you feel cozy and calm in one room but tense and slightly feral in another—spoiler alert—it’s probably the lighting.
As an interior designer, I don’t just choose lighting for how it looks. I choose it for how it makes you feel. And yes, there is science behind that warm glow.
So grab your coffee (or wine—no judgment), and let’s shed some light on this whole lighting thing.

Lighting Affects Your Mood & Health (More Than You Think)
Light impacts your circadian rhythm—your body’s internal clock that controls sleep, hormones, focus, and energy levels.
Cool, harsh light can make you alert… or anxious
Warm, soft light can help you relax and wind down
Poor lighting can lead to eye strain, headaches, disrupted sleep, and general crankiness
Translation: Lighting isn’t just décor—it’s wellness.
Incandescent vs LED: What’s the Deal?

At a glance, both light up a room—but how they create light, how long they last, and how they affect your home are very different. Old-School Incandescent Bulbs create light by heating a tiny metal filament until it glows. Most of the energy actually turns into heat, not light. LED Bulbs (Light-Emitting Diodes) produce light through electrons moving in a semiconductor—no glowing filament, very little heat.
Incandescent bulbs are charming, but environmentally… not so charming.
Why they’re tough on the planet:
About 90% of the energy they use is wasted as heat
Require more electricity, increasing demand on power plants
Burn out quickly → more frequent replacements → more waste
Short lifespan means more manufacturing, packaging, and transport
In simple terms: Incandescent bulbs work harder, burn out faster, and leave a larger carbon
footprint.
What they’re known for:
Warm, golden, flattering light
Cozy and familiar feel
Excellent color accuracy
Downsides:
Very inefficient (lots of wasted energy)
Burn out quickly
Get hot to the touch-some even dangerous and lead to fires.
Largely phased out due to energy regulations
What About Toxic Materials?
Incandescent bulbs: generally safe but inefficient
CFL bulbs:(Compact Fluorescent Lamp) contain small amounts of mercury (problematic if broken)-absolutely no need for them!
LED bulbs: mercury-free and safer to dispose of
Another win for LEDs.
LED Bulbs (Not All Are Created Equal)
Early LEDs gave us trust issues. They were cold, blue, and made everyone look like they hadn’t slept since 2009.
But here’s the good news:High-quality LEDs today are dramatically better—and when chosen correctly, they’re healthier for your home and the planet.
LEDs were designed with efficiency in mind—and the environmental benefits are significant

Why LEDs Are Better For The Environment
Use up to 75–80% less energy than incandescent bulbs
Last 10–25 times longer, reducing landfill waste
Lower energy demand = fewer fossil fuels burned
Produce minimal heat, reducing cooling needs in your home
When you switch to LED lighting, you’re not just saving money—you’re reducing overall energy consumption at scale.
Pros
Energy-efficient (up to 80% less energy)
Long lifespan (years, not months)
Available in warm, soft tones
Less heat = safer + cooler homes
Cons
Cheap LEDs = bad vibes
Low-quality bulbs can flicker and strain your eyes
Designer tip: Spend a little more on good bulbs. This is not where you want to bargain-bin your way into headaches.
Brightness vs. Temperature: What’s the Difference?
When choosing a light bulb, people often mix these two up—but they’re actually two totally different things.
Brightness = How Much Light
Measured in lumens
Brightness tells you how strong the light is—not the color.
More lumens = brighter light
Fewer lumens = softer, dimmer light
Think: Brightness = volume(low to high)
Example:
450 lumens → afternoon/sunset brightness
800–1,100 lumens → mid-morning/high noon-brightness ( sunglasses needed kind of brightness)
Temperature = Color of the Light
The temperature of light is measured in Kelvins (K).
Temperature describes how warm or cool the light looks.
Lower Kelvins = warmer, golden light
Higher Kelvins = cooler, whiter/bluer light
Think:Temperature = mood(warm to cool)
Example:
2200K–2700K → warm, cozy, relaxing
3000K–3500K → clean, balanced
4000K+ → cool, crisp, energizing
Designer Shortcut
Choose brightness (lumens) based on how much light the room needs
Choose temperature (Kelvins) based on how you want the room to feel
That’s it. Simple.
Why Higher-Quality LEDs Are Better for Your Health
Good LEDs:
Reduce flicker (which causes eye strain and fatigue)
Have better CRI (Color Rendering Index) :
CRI Levels (Simple Breakdown)
80 CRI → Basic, acceptable (many standard LEDs)
90+ CRI → Excellent, design-grade lighting
95+ CRI → Near-daylight accuracy (best for homes)
Support healthier sleep cycles when using warm temperatures
Last longer = less waste
Your eyes, nervous system, and electricity
bill will thank you.

Final Thoughts from Your Designer Friend
Lighting is one of the most overlooked design decisions, yet it has the biggest impact on how your home feels day to night. You can have the prettiest furniture, the perfect paint color, and the dreamiest pillows—but if your lighting is wrong, the room will never feel right.
Good lighting:
Supports your mood
Improves sleep
Makes your home feel intentional and cozy
And yes—makes you look better too
If you’re ever unsure, just remember my golden rule: Warm light for living. Cool light only where you must.
Here’s to happier homes, better sleep, and lighting that actually loves you back.
