A dream come true...an analog LED strip with both RGB and Cool White LEDs...It's so........bbbeeeaaaaauuuttttiiiifuuulllll!!!
These LED strips are fun and glowy. There are 60 RGB and Cool White LEDs per meter - you can control the entire strip at once with any microcontroller and three transistors. The way they are wired, you will need a 9-12VDC power supply and then ground the R/G/B/W pins to turn on the colors. Use any NPN or N-channel MOSFET (although the big powerful kind is good for a large strip) and PWM the inputs for color-mixing.
This is the 60 LED-per-meter RGB + Cool White version. We also have this in RGB + Warm White. We splurged and got the weatherproof kind with a white flexi PCB. Great for decorating your bike or art project, costuming or funky fashion.
For powering, a good 12V supply is key. The one we carry will do well for fixed installations. For portable use, we suggest a 8xAA battery holder
Please Note: these strips are weatherproof so they'll be more rugged than uncovered strips, but they not tested for long term submersion in water, especially chlorinated water, or exposed to UV (eg sunlight) for extended periods of time. They are for indoor use or light outdoor use without direct sun/water. That means you cannot put them into a pool, lake, aquarium, etc. The silk-screening and LED brightness of the strips may vary slightly from reel to reel
You can cut this stuff pretty easily with wire cutters, there are cut-lines every 5cm (3 LEDs each), and trim off the weatherproof cover. Solder to the 0.1" copper pads and you're good to go.
They come in 4 meter reels, and are sold by the meter! If you buy 4m at a time, you'll get full reels. If you buy less than 4m, 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.
