What is small edison screw?
A Small Edison Screw (SES) is a type of light bulb base with a 14 mm diameter threaded metal cap, commonly known as E14.
- “E” = Edison screw (named after Thomas Edison)
- “14” = 14 millimeters (diameter of the base)
It’s widely used in Europe, the UK, and many other regions for smaller lighting fixtures.

🔍 Quick Breakdown
| Feature | Details |
|---|---|
| Base type | Edison screw |
| Size | 14 mm diameter |
| Code | E14 |
| Common use | Decorative lighting |
| Regions | Europe, UK, Ukraine |
🔧 How the Edison Screw Actually Works
The E14 base isn’t just mechanical — it’s also electrical:
- The threaded metal shell = one electrical contact (neutral)
- The small metal tip at the bottom = second contact (live)
- When screwed in, the bulb completes the circuit inside the socket
👉 This simple design is why Edison screw bulbs are still used worldwide over 100 years later.
Where You’ll Find E14 Bulbs
SES bulbs are typically used in:
- Chandeliers
- Wall sconces
- Table lamps
- Decorative fixtures
- Appliance lighting (sometimes)
Think of them as the “smaller cousin” of the standard E27 screw.
Common Types of E14 Bulbs
1. Candle Bulbs
- Most popular E14 shape
- Used in chandeliers
- Often decorative (filament-style LEDs)

2. Globe Bulbs
- Round shape
- Softer, ambient lighting
3. Reflector / Spot Bulbs
- Directional light
- Used in accent lighting

4. Smart E14 Bulbs
- Wi-Fi / app-controlled
- Color changing, dimmable

⚖️ SES vs Other Bulb Bases
| Type | Code | Size | Common Use |
|---|---|---|---|
| Small Edison Screw | E14 | 14 mm | Lamps, chandeliers |
| Medium Edison Screw | E27 | 27 mm | Main household bulbs |
| Candelabra (US) | E12 | 12 mm | US decorative lighting |
👉 Important:
- E14 ≠ E12 (they look similar but are NOT interchangeable)
💡 Lumens vs Watts (Critical Buying Tip)
Most people still think in watts — but that’s outdated.
| Old Wattage | LED Equivalent | Brightness (Lumens) |
|---|---|---|
| 40W | 4–6W LED | ~400–500 lm |
| 60W | 6–9W LED | ~700–800 lm |
👉 Always choose based on lumens, not watts.
✅ Pros & Cons of small edison screw?
Pros
- Great for decorative designs
- Works with LED, halogen, incandescent
- Widely available in Europe
- Compact → fits elegant fixtures
Cons
- Easy to confuse with similar sizes (E12)
- Not ideal for main room lighting
- Lower brightness (usually)
🌡️ Color Temperature (Mood Matters)
| Temperature | Look | Best Use |
|---|---|---|
| 2700K | Warm yellow | Bedroom, cozy lamps |
| 3000K | Soft warm | Living room |
| 4000K | Neutral white | Kitchen, bathroom |
| 6000K+ | Cool white/blue | Workspaces |
👉 For chandeliers (E14), 2700K–3000K is ideal.
⚠️ Dimmable vs Non-Dimmable (Very Important)
Not all E14 LED bulbs can be dimmed.
- If you use a dimmer switch:
- You MUST buy “dimmable” E14 bulbs
- Otherwise:
- Flickering
- Buzzing
- Or the bulb simply won’t work
🔥 Heat & Safety Facts
- LED E14 bulbs produce ~80–90% less heat than incandescent
- However:
- Cheap LEDs can overheat in closed fixtures
- Always check: “suitable for enclosed fixtures”
👉 This matters especially for chandeliers and decorative lamps.
⚡ Buying Tips (Important)
- ✔ Check “E14” on the packaging
- ✔ Choose LED for efficiency
- ✔ Match wattage or lumens to your needs
- ✔ Pick the right shape (candle, globe, tubular)
- ✔ For ovens → buy heat-resistant SES bulbs
FAQs
Is SES the same as E14?
Yes — SES = E14 (just different naming).
Can I use E27 instead?
No. It’s much bigger and won’t fit.
Is SES used in the US?
Not commonly. The US uses E12 instead.
Are SES bulbs bright enough?
For lamps and decorative use — yes.
For main lighting — better use E27.
Can I use an E14 bulb in an E27 socket?
Not directly.
E14 is smaller than E27
You’ll need an adapter (E14 → E27)
👉 Without an adapter, it won’t fit.
🧠 Final Verdict
The Small Edison Screw (E14) is a compact, versatile bulb base mainly used for decorative and secondary lighting. It’s extremely common in Europe and perfect for chandeliers, lamps, and stylish fixtures—but not ideal as your primary light source.
