Compatibility & Installation Notes
Match the BA15D socket and 100–130V AC (120V nominal) supply. Turn power off and let the old lamp cool before replacement. Compare lumens with the fixture’s recommended original lamp; lower LED wattage alone does not permit a brighter replacement. Use compatible LED dimming equipment and check its load range. Verify any ceiling-fan receiver, timer, photocell or hi/lo control supports the lamp and LED load. Damp-location and enclosed-fixture use still require protection from direct water and compliance with the manufacturer’s thermal guidance. For this model wattage, the manufacturer’s guide lists a minimum enclosed shade size of 4.5 × 4.5 × 4.5 inches (91 cubic inches). Confirm the two bottom contacts and bayonet arrangement. Do not substitute a BA15S single-contact lamp or assume this nominal 120V model belongs in an automotive 12V socket.
Frequently Asked Questions
Will it replace any bayonet bulb?
No. It requires a BA15D double-contact bayonet socket and 100–130V AC supply. BA15S single-contact and automotive 12V lamps are different electrical arrangements.
How much light does it provide?
The published output is 450 lumens at fixed 2700K. Compare that output with the fixture’s recommended lamp.
Can I use it with a dimmer?
Use compatible LED dimming equipment and check the control’s load range and the fixture’s requirements.
What measurements should I check?
Check the 2-1/4-inch overall length and 11/16-inch maximum diameter against the socket position, shade opening and lamp space.
Why Buy from Big Frog Supply?
Choose the BA15D 4.5W 2700K for 450 lumens through a 120V double-contact bayonet socket. Its 2-1/4-inch overall length and 11/16-inch diameter help you check a narrow display or decorative fitting. Verify both contacts and voltage before replacing a similar-looking automotive or single-contact bayonet lamp.
