Note these are not 'NeoPixel' LED strips, you can turn the entire thing on/off or dim it with a PWM power signal but you cannot turn on individual LEDs.

There's also three 'set screw' attachment screws that would normally be used to friction-fit these to a lens or cowl. There's no guarantee of how the screws are offset from the power connection, it seems different on each LED ring.

The Tiffen Company is a leading American manufacturer of imaging accessories for the consumer/professional imaging, Motion Picture & Television and broadcast industries.

Originally, this ring came with a dimmer, but it was built into the wall adapter so not very useful for portable projects. This guide on analog RGB LED strip control will show you how to dim a 9V LED - you'll want a microcontroller with a PWM output, and a single N-MOSFETs to control the power

If you buy less than a full reel, you'll get a single strip, but it will be a cut piece from a reel which may or may not have a connector on it. If the piece comes from the end of the reel, the connector may be on the output end of the strip!

This LED Ring Light is designed for use with microscopes but we kinda like the design and think it could be a really nice LED element for costuming or lighting effects or... something else? Of course you could also just use it as a great addition to your photo and video projects. It's super illuminating with cool, soft, light, perfect for photo studio lighting. We've also seen these used as microscope illuminators for intense, focused, and shadow-free detail work.

Hook it up with 9V power, and you're one step closer to lights, camera, action! You'll need to provide 9V power, it won't work with 5V for sure. This wall adapter will do the job for when you have an outlet. If you want to power from a USB supply, try this USB-9V booster cable. For DIY connections, check out our 2.1mm male DC plugs.

Adafruit NeoPixel Digital RGB LED strips come to us in 4 or 5 meter reels with a 2 or 3-pin JST SM connector on each end and separated power/ground wires as shown in the picture below. If you order a full 4 or 5 meters, you get the full reel with both connectors installed.
