These LEDs are designed to operate on a \u003cstrong\u003eDC 12V power supply\u003c\/strong\u003e. Always ensure you are using a regulated DC 12V source and never connect them directly to AC mains without a suitable driver or adapter.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Do these LEDs need resistors if used with a 12V supply?\u003c\/h4\u003e\n\u003cp\u003eA: These bulbs are pre-wired and rated for DC 12V, meaning any necessary current-limiting components are already factored into the design. Simply connect to a stable DC 12V source and they are ready to use.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use these LEDs outdoors?\u003c\/h4\u003e\n\u003cp\u003eA: While these LEDs are great for architectural and decorative outdoor lighting accents, they should be kept away from direct moisture or water exposure. For fully outdoor use, ensure they are housed in a suitable weatherproof enclosure.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What colors are available for the 3mm pre-wired LED bulbs?\u003c\/h4\u003e\n\u003cp\u003eA: These LEDs are available in \u003cstrong\u003e10 color options\u003c\/strong\u003e: Red, White, Blue, Green, Yellow, UV, Pink, Crystal Blue, Warm White, and Orange — making them perfect for any creative lighting project.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What voltage do these 3mm pre-wired LED bulbs require?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"These LEDs are designed to operate on a DC 12V power supply.
