Single Ended nOOds, 300mm long Flexible LED Filament, Warm White 3V

So here we are talking about this cool looking thing called Single Ended nOOds, basically it is a type of flexible LED filament which is 300mm long which means around 30 cm, like one standard scale. It glows in warm white color and works nicely with just 3V DC.

What is it, actually?

This LED filament is not like your usual small LED or strip LED. This one looks like a glowing noodle—yeah bro, that is why they call it “nOOds”. It's a single-ended filament which means only one end is active for power input. The other end just hangs freely or is just for mechanical support.

It is bendable, super thin, flexy and glows uniformly from end to end. So when we switch it ON with 3V, the full 300mm length glows in warm white,which is like yellowish soft light not bluish white.

Technical Specs

Here are the main technical features of this 300mm LED filament noodle:

• Length: 300mm (12 inches)
• Color Temperature: Warm White (~2700K to 3000K)
• Voltage: 3.0V DC (Nominal)
• Current: Around 70mA to 100mA (depends on actual voltage)
• Power: Around 0.3W
• Connection Type: Single-ended (Only one side needs connection)
• Material: Flexible glass core with LED phosphor coating
• Visibility: 360-degree viewing angle, glows all around
• Mounting: Can be bent, looped, glued, or suspended

How to Power It?

To light this up properly we need a clean 3V DC source, current-limited to avoid overdriving. You can use:

• 2 x AA or AAA cells (3V total)
• A regulated 3V DC adapter
• A Li-ion 18650 with a 3.3V low-drop diode in series
• Arduino 3.3V pin (but only for quick tests, not for long-time powering)

But yeah, the current draw is like 80mA so do not try to drive it directly from microcontroller pins—use a transistor or MOSFET switch.

What is Special in this Single-Ended Design?

Normal LED filaments have two ends for power, like a bulb filament. But this one is different, only one end has wires, the other end is dummy. So it is more aesthetic and clean for design.

It also makes wiring easier—just stick one side into your holder or fitting, and no need to hide wires on the other end.

Applications – Where Can We Use It?

So buddy, this thing is perfect for DIY lighting designs, especially where looks and soft glow matter. Here are some ideas:

• Custom hanging lamps
• Retro LED bulb designs
• Creative lighting sculptures
• Signboards with glowing outlines
• Wearable costumes (with care)
• Light paintings or photography props
• Mood lamps with artistic twist

Precautions to Keep in Mind

• This filament is glass-based, so do not bend it too hard, or it can break.
• Do not power it with more than 3.3V or it may burn out.
• Always use current-limiting resistor if power source is not constant.
• Soldering can be tricky—use low heat and quick hand.
• Avoid moisture and humidity.
• Pro Tips for Using These nOOds
• Use clear epoxy or silicone tubes to make custom light rods.
• You can twist or curve it gently and stick on a glass panel for artistic light.
• For controlling brightness you can use PWM dimming via transistor.
• To increase light output, use multiple in parallel with proper current sharing.

Final Words

So this 300mm Single Ended Flexible LED Filament – Warm White 3V, aka nOOds, is like a mini light saber but super soft and classy. Perfect for anyone who loves combining electronics with visual art. It’s small, flexible, low voltage and eye-catchy. If you want to make your LED project look awesome then just throw one or two of these in and boom—it is glowing like magic!
