DC3V 130 300mm Flexible Filament LED Filament Edison Bulb LED Bead Diodes Light Accessories Warm Light 2200K 130mm

really bright, good value, only tried one color so I can only say the yellow is fairly accurate (ref other review photos too), definitely put a resistor on this as suggested by the other posts (it'll work without but eventually burn out). can support higher voltages but will get warm and die...also as pointed out in other reviews, these are like resistors so if you put them in series you can run 3 with a 9v (turn on voltage is ~3 each)...but if you need something longer there's other filament options. these are fairly durable, but don't go stretching it really taut because that'll break them. shipping wasn't 2-day but it was worth buying a bunch ahead of time.

DIY miniature neon sign project for hobby. Glad to find could “sew” them through holes in test jig for making a miniature neon sign effect. Very flexible like a piece of angel hair pasta. Able to take a sharp bight and bend back on itself. But be careful with these, no tension, heavy use. Maybe ok for occasional wearable use as in cosplay. You’ll love how flexible these are and maybe dislike how short they are available. As a model builder, plan ahead to have these fixed in placed once and then left alone. 3V DC max, ever. End with tiny punched hole is red/plus. For dollhouse scale interior, the only challenge was going low enough voltage from pre-existing setup. Maybe need to try to test a wide variety of these flexible led elements. Much brighter than EL wire could ever be. Read more

I bought these for a friend to put in/on his door Christmas wreath. It lights it up beautifully so it's easy to see from the road. (It's important you know that if you wish to connect them, you will need to solder the ends together. And you will need a power supply. You can use batteries, but my friend uses a variable voltage power supply.) Read more

Pretty cool new kind of light string with variable voltage input. 5v is waaay too bright (and it gets hot) so i took a pic at 3v. The lower the voltage the more you can see the individual diodes and since its thin it may not fit all breadboard holes great either but still cool concept. Read more

The media could not be loaded. Electrical Engineer here. Using these inside a white 3D printed model for a nice glow. For anyone that doesn't want to do the math with these, use the specs and use Chat GPT, it will guide you. (Pay attention to the positive and negative sides of the LED strip) But here is what I used if you want to replicate what I did: Bought a: 15Volt 3Amp wall adapter. Two 10ohm resistors in series (connected in a line...or just google it). Three 300mm LEDs + Two 160mm LEDs (in series, and in series with the resistors. A big loop back to the power supply.) Will work with a switch or button, will also work without one, but a switch is recommended. Read more

The product is great but you can't talk with them. I never received one of the led out 2 that was ordered. Read more

I bought these to test out for use in various projects. They only take 3V and produce a good bit of light. Easy to control with an Arduino, really no different than running a plain LED. The leads are a bit small but I managed to tin and solder wires to them without ruining anything. Be sure to use a resistor - I forgot in my first experiments and the noodle got quite hot. You can see in the photo that they're quite flexible, at least in one direction. Read more

I use this particularly for dioramas. Only not 5 stars because of the ship time. Would recommend though. Read more
