slate-data-type=\"image\"\u003e\n\u003cp\u003eThis 100-piece assortment delivers exactly what builders need for mixed-color LED projects: 5 mm through-hole diodes in nine distinct colors including cool white, warm white, red, green, blue, yellow, orange, pink, and purple. Each diode is rated for standard 1.5 V forward voltage and 20 mA forward current, making them straightforward to drive from common 3 V coin cells, 5 V logic outputs, or simple resistor-limited circuits.\u003c\/p\u003e\n\u003cp\u003eBecause the kit contains a full hundred pieces rather than tiny sample packs, you can complete multiple prototypes, repair jobs, or classroom builds without running out of any single color mid-project. The through-hole package fits standard 0.1-inch breadboard and perfboard layouts, so you can move quickly from breadboard testing to permanent soldered assemblies.\u003c\/p\u003e\n\u003cp\u003eHobbyists use these LEDs for custom indicator panels, model lighting, Arduino or Raspberry Pi status arrays, RC vehicle light bars, and educational electronics kits. The color variety lets you match specific themes or create visual sequences without ordering separate bags for each hue.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e100 total diodes across nine colors\u003c\/li\u003e\n\u003cli\u003e5 mm diameter, through-hole mounting\u003c\/li\u003e\n\u003cli\u003e1.5 V forward voltage, 20 mA forward current\u003c\/li\u003e\n\u003cli\u003eReady for breadboard, perfboard, or soldered projects\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Electronics","offers":[{"title":"100pcs Red","offer_id":58072850727260,"sku":"14:200003699#100pcs Red","price":1.74,"currency_code":"GBP","in_stock":true},{"title":"100pcs Orange","offer_id":58072850760028,"sku":"14:200002130#100pcs Orange","price":1.94,"currency_code":"GBP","in_stock":true},{"title":"5 color each 20pcs","offer_id":58072850792796,"sku":"14:193#5 color each 20pcs","price":1.92,"currency_code":"GBP","in_stock":true},{"title":"100pcs Purple","offer_id":58072850825564,"sku":"14:10#100pcs Purple","price":2.01,"currency_code":"GBP","in_stock":true},{"title":"100pcs Warm White","offer_id":58072850858332,"sku":"14:29#100pcs Warm White","price":1.92,"currency_code":"GBP","in_stock":true},{"title":"10 color each 10pcs","offer_id":58072850891100,"sku":"14:173#10 color each 10pcs","price":2.58,"currency_code":"GBP","in_stock":true},{"title":"100pcs Pink","offer_id":58072850923868,"sku":"14:175#100pcs Pink","price":2.02,"currency_code":"GBP","in_stock":true},{"title":"100pcs White","offer_id":58072850956636,"sku":"14:365458#100pcs White","price":1.75,"currency_code":"GBP","in_stock":true},{"title":"100pcs Blue","offer_id":58072850989404,"sku":"14:350850#100pcs Blue","price":1.69,"currency_code":"GBP","in_stock":true},{"title":"100pcs Green","offer_id":58072851022172,"sku":"14:350852#100pcs Green","price":1.76,"currency_code":"GBP","in_stock":true},{"title":"100pcs Yellow","offer_id":58072851054940,"sku":"14:350853#100pcs Yellow","price":1.77,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1000\/2042\/0956\/files\/Sc6bef6bdcde8423287930ef2492a69ccF.webp?v=1781416268"}],"url":"https:\/\/robotbuilder.co\/collections\/lights.oembed","provider":"Electronics","version":"1.0","type":"link"}
