Miniature 3V LED Lighting


Product Description


These 3 Volt LEDs are the perfect size for miniature projects: dollhouses, dioramas, art projects, railroad scenes, and more.

We now offer the LEDs in a variety of sizes:

  • MEGA Perfect for brightly lighting a small room in quarter (1:48) scale. Only 1 LED is needed. These are super bright! When a single, central ceiling fixture is desired, we recommend using a MEGA with a jewelry finding. The amount of light may be reduced by painting over the LED with a white/off-white craft paint.
  • CHIP The most popular size. One chip will light a small room in quarter scale, but it will be a softer light. These are the size of LEDs that we include in the majoritly of our structure kits. CHIPS also work well for creating burning coals in one inch (1:12) scale fireplaces and stoves. 
  • NANO We love these for lighting tiny areas in one inch and quarter inch scale scenes (glitter houses, bookcases, china cabinets, jack o'lanterns, Christmas trees, burning coals, etc.). They're also great when just a small amount of ambient light is desired (place an LED behind a window scene, for example).
  • PICO These are incredibly tiny! They work well to light small areas in 1/144 scale.

Why use LEDs? 

LEDs are much more efficient than incandescent bulbs.
  • They don't become hot (perfect for glitter houses, Christmas trees, and places where the lights will be dangerously close to flammable and/or fragile items).
  • They last a LONG time - 10 years/10,000 hours. It's very unlikely that you will have to tear apart your project to replace an LED.
  • They provide a lot of light. In fact, sometimes they are brighter than is needed for our miniature projects. Thankfully there are ways to cut down the amount of light (discussed in the LED lighting tutorial).
  • They are tougher to break than an incandescent bulb because there isn't a filament.

How are the LEDs powered?

All of our 3 Volt LEDs are operated by a 3 Volt battery and switch unit (shown at left). The battery holder and switch is easy to hide in a base unit, attic, under furniture, etc. Do NOT use these 3V LEDs with a standard dollhouse transformer; it will ruin the LEDs.  

How do I hook up the LEDs to the battery?

It's easy! We've written a step-by-step tutorial: FREE LED wiring tutorial If you have more questions, please contact us.

Do I have to solder?

No. There is no need for soldering the wires. A tight connection is created by using the shrink tubes which are included in the battery holder and switch unit.

How long are the wires of the LEDs?

The wires are 8 inches (20cm) long. The wires on the battery holder and switch unit are 4 inches (10cm) long. If you require a longer length for your project, wired connectors are available.

How many LEDs are needed for a project?

Keep in mind that when working with dollhouse miniatures, we recommend using these systems to light smaller scale rooms or dollhouses (half 1:24 scale, quarter 1:48 scale, and microscale 1:144). They also work well for lighting small areas in 1" 1:12 scale dollhouses (china cabinets, under cabinet lighting, Christmas trees, fireplaces, glitter houses, etc.) We do not recommend using these to light an entire 1:12 scale dollhouse. To help you decide the quantity and size of the LEDs for your project, please see the tips above. We recommend using 1-10 CHIPS on a 3V battery. 10 CHIPS will run for about 12 hours. 3 CHIPS will run on a single battery for about 40 hours.

Where can I find the battery?

A battery is included with the battery holder and switch unit. The replaceable battery is a common size which is available from drug/convenience stores.
