3 Volt Solid Bulb LEDs make the perfect addition to any hobby project. Available in 3 sizes and 10 colors, the possibilities are endless.

LED Bulb Sizes:
  • 5mm LEDs: Our biggest and brightest bulb size. Great for G scale or anywhere you need a lot of light. 
  • 3mm LEDs: Perfect for 1:18 scale, 1:43 scale or O scale.
  • 1.8 mm LEDs: Our smallest bulb size offers a scattered light beam that is less directional than the 3mm and 5mm bulbs. 1.8mm is good for smaller scales or small tight spaces. If you need even smaller LEDs make sure to check out our Chip LEDs.

Bulb LEDs vs Chip LEDs

What's the difference between bulb and chip LEDs?

Evan Designs bulb LEDs have a metal light producing diode encased in a rounded silicone lens. This lens has a focusing “spotlight” effect. The top of the bulb can be sanded to widen light spread.

Evan Designs Chip LEDs are flat and surface mount. They have a wide less focused light spread and no “bulb” shape. 

Warm White vs Cool White: Which one is right for me?

  • Warm White: Warm White LEDs match the warm glow of incandescent lights and are perfect for lighting rooms, car headlights, or anywhere you want a more classic warm light glow.
  • Cool White: Cool White LEDs have the cool glow of fluorescent lights. This slightly bluish light is perfect for shop or warehouse lights as well as newer car headlights.

We have these LEDs in several voltages, so you can get the right voltage for your project!

Powering your 3 Volt LEDs

These are 3 volt LEDs. They come pre-wired to 8 inches of insulated wire and the correct 3 volt resistors if needed. Note that not every color LED needs a resistor to operate at 3 volts, such as white and blue LEDs.
