The LED is very bright, with 90 Lumens in a 140 degree lambertian pattern. Compared to most LEDs, you would say this is 30,000 millicandela. Either way, its incredibly bright! The output is a 'cool' 6000K pure white, not a 'warm' incandescent-looking white.\u003cbr\u003e\n\n\u003cbr\u003e\n\nThe LED is mounted onto an aluminum PCB for heatsinking, and it also makes it easy to solder in. Simply connect to the big + and - pads on the PCB (there are two of each).\u003cbr\u003e\n\n\u003cbr\u003e\n\nThe best way to drive these LEDs is constant current, @ 350 mA, but you can get away with under-driving for compactness. At about 3V, the LED draws ~200 mA, so connect two Alkaline batteries up directly with no resistor for a basic bright lamp. You can also try driving it directly with a 3.3V power supply, that will probably work OK as well (although its not ideal) - that's what we did when we made a vintage LED bike light using a 1W white LED.\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cdiv class=\"row\"\u003e \u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\u003cp\u003eDatasheet for the BL-HP20AWCL 1W LED\u003c\/p\u003e\u003c\/div\u003e \u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e \u003c\/ul\u003e \u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e \u003c\/div\u003e","brand":"The Pi Hut","offers":[{"title":"Default Title","offer_id":55919650242633,"sku":"fbf1787257429759","price":2.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0937\/7185\/7993\/files\/1-watt-cool-white-led---heatsink-mounted_1.jpg?v=1787257434","url":"https:\/\/streetclad.shop\/products\/1-watt-cool-white-led-heatsink-mounted","provider":"My Store","version":"1.0","type":"link"}
