100-Pack Warm White C9 LED Replacement Bulbs
This 100-piece set provides warm white C9 LED bulbs with an E17 base for screw-in replacement on existing string lights. The pack suits homeowners and decorators who need a large quantity of consistent, shatterproof bulbs for seasonal displays. UL listing confirms the bulbs meet recognised safety requirements for indoor and outdoor use.
Sustained Outdoor Operation
The shatterproof and waterproof PC shell protects the LEDs from rain, snow and temperature swings, so brightness remains stable across the whole season rather than fading after a few nights. Dimmable circuitry lets you lower output for subtle ambience or raise it for full brilliance without flicker during extended runs. UL certification means the electrical construction is verified for continuous holiday-period duty.
E17 Base and Shatterproof Shell
Each bulb screws directly into standard E17 sockets, so installation requires no tools and no rewiring of the string. The polycarbonate shell resists impacts that would crack glass bulbs, reducing replacement work when lines are handled or stored. Colour variants are sold separately, allowing you to mix hues later without changing the base hardware.

Questions about this item
Do the 100 C9 LED bulbs run cool enough to leave on all day without overheating the sockets?
The LED design produces minimal heat compared to incandescent bulbs, reducing socket stress during extended runs.
What existing string-light sets will accept these replacement bulbs?
They fit standard C9 sockets, so any light string with matching C9 bases will work.
Can I mix these warm-white bulbs with older coloured C9 bulbs on the same string?
Yes, the identical C9 base and voltage let you combine warm white with red, green, blue, yellow or orange bulbs on one circuit.
