How to select the correct lamp

Choose the exact base and voltage, then compare overall length, glass finish, lumens, colour temperature, dimming and fixture enclosure.

Compatibility and safety

Many decorative lamps prioritize appearance over light output. Tinted glass can reduce usable lumens, and not every LED filament lamp is suitable for enclosed fixtures.

Important: The library describes a lamp format, not a particular product. A shared shape does not guarantee matching voltage, base, dimensions, light distribution or control requirements. Confirm the fixture label and product datasheet, or ask a Bulb World lighting specialist.

Replacement Notes

Choose the exact base and voltage, then compare overall length, glass finish, lumens, colour temperature, dimming and fixture enclosure.

Capability Warning

Many decorative lamps prioritize appearance over light output. Tinted glass can reduce usable lumens, and not every LED filament lamp is suitable for enclosed fixtures.
