Here's the easiest way to add a cool white LED element for costuming or lighting effects or... something else? Of course, you could also just use this Cool White LED Ring Light + USB Cable with On/Off Switch as a lighting addition to your photo and video projects. No soldering or wiring required as this version is ready to go!
Deceptively small and slim, this LED ring is very bright and could not be easier to use. Hook it up with 5V power and 500mA current capability, and with a flick of the on/off switch, you've got the quickest way to make all your projects light up.
Please note, this ring has a lot of LEDs on it and since its not in a heatsink case it will get hot - if you want to keep it on for more than a minute, either add a heatsink, PWM it or drive it at a lower voltage by adding a diode or resistor in series to reduce the current.
These are not 'NeoPixel' LEDs, you can turn the entire thing on/off or dim it with a PWM power signal, but you cannot turn on individual LEDs.
We also have just the ring, without an attached USB cable. This one is just the easiest for integration.
Please note: You may get a USB power cable that is white with a pushbutton, or black with a rocker switch. The LED ring is the same for both versions.
