{"title":"Cool White LED Ring Light PCB - 70mm Diameter - 5V Power","handle":"cool-white-led-ring-light-pcb-70mm-diameter-5v-power","url":"/products/cool-white-led-ring-light-pcb-70mm-diameter-5v-power","description":"This cool white LED ring light is a slim, bright PCB ring that makes it easy to add even lighting to costuming, photo/video projects, or any build that needs a clean ring of light. Just supply 5 V at up to 500 mA and it lights up immediately — no addressable LED library or microcontroller required.\n\nThe entire ring switches on/off together (these are not individually addressable NeoPixel LEDs). You can dim it using a PWM signal on the power line.\n\nKey Features\n\n\nCool White LEDs – Bright, even illumination in a ring layout\n\n70 mm Diameter – Compact ring-shaped PCB\n\n5 V Power – Simple two-wire connection, up to 500 mA\n\nPWM Dimmable – Control brightness with a PWM signal\n\nSlim Profile – Thin PCB fits into tight spaces\n\n\n\nWarning: This ring has many LEDs and no built-in heatsink — it will get hot if left on continuously. For extended use, add a heatsink, use PWM to reduce duty cycle, or add a series diode/resistor to lower the current.\n\n\nIdeal For\n\nPhotography and video ring lighting\nCosplay and costume lighting effects\nMacro photography illumination\nDecorative and accent lighting\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2903,"title":"Default Title","sku":"AF-5138","price":17.18,"on_sale":false,"in_stock":true,"available_quantity":23,"option1":"Default Title"}]}
