The 7 Essential Light Bulb Base Sizes
Key Insights
1. E26 (Standard Butterfly/P obtencia Base)
Most common in North America, E26 is the iconic 26mm-wide base with two screw threads. Perfect for general lighting, ceiling lights, and table lamps. Bulbs include incandescent, LED, and halogen.
Top Tip: E26 is compatible with 90% of household fixtures—easy, reliable, and versatile.
2. E14 (Bibi Screw Base)
Ideal for niche fixtures like vanity lights, candlesticks, and wall sconces, E14 features a smaller base with a stylized “bibi” design. Uses 14mm base width and only one thread.
Why Choose E14: Creates intimate, soft lighting while fitting into compact spaces.
3. ED head (European Screw Base)
Measuring 30mm, the ED head is standard in many European fixtures and often compatible with North American E26 bases through an adapter. Ideal for pendant lights, chandeliers, and recessed fixtures.
Bonus: Often supports dimming and features a sleek, modern look.
4. G9 (Flower Bulb Base)
Small and cylindrical, G9 bulbs shine in, accent lights, and decorative fixtures. The tiny base ensures easy threading in space-constrained settings.
Niche Use: Great for emergency lighting, holiday decor, or small enclosures.
5. G4 and G25 (Candelabra or Spark Filter Bases)
G4 (4mm base) is ultra-compact, popular for vintage-style lamps and embedded fixtures. G25 (25mm base) balances size and performance for specialized chandeliers and fixtures needing a classic flair.
Style Note: Perfect if you want vintage charm with modern reliability.

6. BR30 and MR16 Base Types (Can Be Cross-Applied)
Though not bases per se, BR30 (and its smaller MR16) bases allow balloon-style bases in industrial and commercial spaces. The 30mm wide base supports high-intensity lighting and dimmable LEDs.
Why They Matter: Extended compatibility opens up creative lighting design options.
7. Ballast Compatible Bases (Industrial & Commercial)
For high-wattage fixtures like fluorescent or HID lamps, look for bases designed to work with specialized ballasts—key in warehouses, stadiums, and industrial settings.
What to Consider: Match base voltage and amperage to prevent overheating.
Pro Tips for Choosing the Right Bulb Base
- Match Size to Fixture: Always bring the old bulb or fixture label to the store.
- Check Base Type First: E26 ≠ ED or G9—don’t confuse screw-based with bayonet or decorative bases.
- Consider Dimming and Color Temperature: Led and smart bulbs expand options—ensure the base supports your tech.
- Factor in Heat and Durability: Smaller bases (like E14) generate less heat; larger bases (ED head) offer better stability.
- Look for Energy Efficiency: Modern E26-compatible LEDs and hybrids offer superior light output and lifespan.
