Want to light up your Minecraft world with automatic illumination? You can absolutely make a Redstone lamp in Minecraft! This tutorial will guide you through every step, from the most basic setup to more advanced, automated designs. We’ll cover what you need, how to connect it, and how to get creative with your new light source.
What You Need for a Basic Redstone Lamp
To build a functional Redstone lamp, you’ll need just a few key items. These are the building blocks of most Redstone contraptions.
Essential Components
- Redstone Lamp: This is your light source. It’s a crafted block that emits light when powered.
- Redstone Dust: This is the “wire” of Redstone. It carries power signals from one component to another.
- Power Source: This is what actually activates the Redstone lamp. Common power sources include:
- Redstone Torch: A stable source of Redstone power.
- Lever: A switch you can toggle on and off.
- Button: A temporary power source that activates for a short time.
- Block of Redstone: A solid block that emits a constant Redstone signal.
Crafting Your Redstone Lamp
Before you can build a circuit, you need the lamp itself.
Recipe for a Redstone Lamp
To craft a Redstone lamp, you’ll need:
- 1 Redstone Dust
- 4 Glowstone Dust
Place one Redstone dust in the center slot of your crafting grid and four Glowstone dust in a square around it.
| Crafting Grid | Slot 1 | Slot 2 | Slot 3 |
|---|---|---|---|
| Row 1 | Empty | Glowstone | Empty |
| Row 2 | Glowstone | Redstone | Glowstone |
| Row 3 | Empty | Glowstone | Empty |
This recipe will yield one Redstone Lamp.
Building the Simplest Redstone Lamp
Let’s start with the most straightforward way to power a Redstone lamp.
Setup 1: Direct Connection
This is the easiest way to get your lamp working.
- Place the Lamp: Put your Redstone Lamp down on the ground.
- Place the Power Source:
- Using a Redstone Torch: Place a Redstone torch directly next to the Redstone Lamp. The lamp will immediately turn on.
- Using a Lever: Place a lever on a block next to the Redstone Lamp. Right-click the lever to turn it on, and the lamp will light up.
- Using a Button: Place a button on a block next to the Redstone Lamp. Pressing the button will briefly power the lamp.
- Using a Block of Redstone: Place a block of redstone next to the lamp. The lamp will light up.
That’s it! Your first Redstone lamp is active.
Expanding Your Redstone Lamp Circuitry
Once you grasp the basics, you can create more complex and useful lighting systems. This involves using Redstone dust to transmit power over distances and through obstacles.
Setup 2: Using Redstone Dust to Connect
This setup allows you to place your power source away from the lamp.
- Place the Lamp: Put down your Redstone Lamp.
- Place a Power Source: Choose your power source (e.g., a lever on a block).
- Connect with Redstone Dust:
- Place a piece of Redstone dust on the block adjacent to your power source.
- Continue placing Redstone dust, creating a path from the Redstone dust near the power source to the block directly next to your Redstone Lamp.
- When you activate the power source (flip the lever, for instance), the signal will travel through the Redstone dust and turn on the lamp.
Tip: Redstone dust can transmit a signal up to 15 blocks. If you need to go further, you’ll need a repeater.
Setup 3: Powering Multiple Lamps with One Switch
Want to light up a larger area? You can connect multiple lamps to a single power source.
- Place Your Lamps: Arrange your Redstone Lamps in a desired pattern.
- Place Your Power Source: Position your lever or button.
- Connect with Redstone Dust:
- Run Redstone dust from your power source to each lamp. You can have Redstone dust run to the block next to each lamp.
- Alternatively, you can create a main line of Redstone dust and branch off to each lamp.
When you activate the power source, all connected lamps will illuminate.
Introducing Redstone Repeaters
Redstone repeaters are crucial for extending Redstone signals and creating more advanced circuits.
What a Redstone Repeater Does
A Redstone repeater has two main functions:
- Signal Strength Restoration: It takes a weak Redstone signal (less than 15 blocks) and boosts it back to full strength (15 blocks).
- Directional Signal Flow: It only allows Redstone signals to travel in one direction.
- Delay: It can introduce a delay to a Redstone signal.
Crafting a Redstone Repeater
You will need:
- 3 Torches
- 1 Redstone Dust
- 2 Redstone Torches
| Crafting Grid | Slot 1 | Slot 2 | Slot 3 |
|---|---|---|---|
| Row 1 | Empty | Redstone Torch | Empty |
| Row 2 | Redstone Dust | Empty | Redstone Torch |
| Row 3 | Empty | Redstone Torch | Empty |
This recipe yields 1 Redstone Repeater.
Using Repeaters in Your Lamp Circuit
- Place your Lamp and Power Source.
- Lay Redstone Dust: Connect them with Redstone dust, but stop before the signal reaches 15 blocks, or where you want to refresh it.
- Place the Repeater: Place a Redstone repeater in the Redstone dust line. Make sure the “input” side of the repeater (the end with the two torches) is facing the power source, and the “output” side (the single torch) is facing the direction you want the signal to go.
- Continue the Redstone Dust: Place more Redstone dust after the repeater.
Now, the signal will travel the full 15 blocks from the repeater. You can place multiple repeaters to extend the signal even further.
Adjusting Repeater Delay
Redstone repeaters can be right-clicked to adjust their delay. Each click adds a 1-tick delay, up to a maximum of 4 ticks. This is useful for timing-based Redstone contraptions.
Introducing Redstone Comparators
Redstone comparators are more complex and can detect different states of Redstone signals and blocks.
What a Redstone Comparator Does
A Redstone comparator has three main functions:
- Signal Strength Detection: It can detect the strength of a Redstone signal.
- Block State Detection: It can detect if a container (like a chest or furnace) has items inside, or if a redstone-powered block is active.
- Signal Output: It can output a signal based on these detections.
Crafting a Redstone Comparator
You will need:
- 3 Torches
- 1 Redstone Dust
- 2 Stone
| Crafting Grid | Slot 1 | Slot 2 | Slot 3 |
|---|---|---|---|
| Row 1 | Empty | Redstone Torch | Empty |
| Row 2 | Stone | Redstone Comparator | Stone |
| Row 3 | Empty | Redstone Torch | Empty |
This recipe yields 1 Redstone Comparator.
Using Comparators for Advanced Lamp Control
Comparators can be used to create lamps that react to specific conditions.
Example: Lamp that lights up when a chest is opened.
- Place a Chest: Put down a chest.
- Place a Comparator: Place a Redstone comparator behind the chest. Ensure the side of the comparator with two torches is facing the chest, and the output side is facing away.
- Place a Lamp: Place a Redstone lamp a short distance away.
- Connect: Run Redstone dust from the output of the comparator to the Redstone lamp.
When you open the chest, the comparator will detect that it has items (even if it’s empty, the presence of the block is enough for a simple signal), and power the lamp.
Using a Block of Redstone as a Power Source
A block of Redstone is a solid block that constantly emits a Redstone signal.
How to Obtain a Block of Redstone
You can craft a block of Redstone by placing nine Redstone dust in a 3×3 square in your crafting grid.
| Crafting Grid | Slot 1 | Slot 2 | Slot 3 |
|---|---|---|---|
| Row 1 | Redstone Dust | Redstone Dust | Redstone Dust |
| Row 2 | Redstone Dust | Redstone Dust | Redstone Dust |
| Row 3 | Redstone Dust | Redstone Dust | Redstone Dust |
This recipe yields 1 Block of Redstone.
Practical Uses for a Block of Redstone
- Constant Lighting: Place a block of Redstone next to a Redstone lamp for a permanently lit area.
- Powering Pistons: Blocks of Redstone are often used to activate sticky pistons, which can then be used to move other blocks or components.
Automatic Lighting with Daylight Sensors
Daylight sensors allow your Redstone lamps to turn on automatically when it gets dark.
What a Daylight Sensor Does
A Daylight Sensor detects the amount of light in its environment. It outputs a Redstone signal that gets stronger in brighter light and weaker in darker conditions.
Crafting a Daylight Sensor
You will need:
- 3 Torches
- 3 Glass
| Crafting Grid | Slot 1 | Slot 2 | Slot 3 |
|---|---|---|---|
| Row 1 | Empty | Glass | Empty |
| Row 2 | Glass | Redstone Torch | Glass |
| Row 3 | Empty | Redstone Torch | Empty |
This recipe yields 1 Daylight Sensor.
Setting Up a Daylight Sensor System
- Place the Daylight Sensor: Position it where it will receive ambient light.
- Place the Redstone Lamp: Put your lamp nearby.
- Connect:
- Simple Setup: Place Redstone dust from the Daylight Sensor to the Redstone Lamp. As it gets dark, the sensor’s signal will weaken, but it will still be strong enough to power the lamp.
- Adjusting for Brightness: You can right-click a Daylight Sensor to change its mode from “always active in daylight” to “always active in darkness.” The default mode is “always active in daylight.” To get a lamp to turn on when it’s dark, you’ll want to configure it for darkness.
- Using a Repeater: If you need to power lamps at a distance, connect the Daylight Sensor to a Redstone dust line, potentially using repeaters to maintain signal strength.
Tip: You can also use a Daylight Sensor to control other Redstone devices, not just lamps.
More Advanced Redstone Lamp Setups
Let’s explore some more creative and functional ways to use Redstone lamps.
Setup 4: Hidden Lighting with Pistons
You can use sticky pistons to reveal or conceal your Redstone lamps.
- Place the Lamp: Position your Redstone Lamp where you want the light to appear.
- Place a Sticky Piston: Place a sticky piston so that when extended, it pushes a block in front of the lamp, turning it off. The piston should be positioned so its sticky face is next to the block that will hide the lamp.
- Place a Block: Place a solid block (e.g., stone) in front of the Redstone Lamp, so the sticky piston can push it.
- Connect Power: Run Redstone dust from your power source (lever, button, etc.) to the sticky piston.
- Add Redstone Dust to Lamp: Connect the same power source to the Redstone lamp. When the piston extends (blocking the light), the lamp should turn off.
How it works: When the piston is powered, it extends and pushes the block, covering the lamp. When the piston is unpowered, it retracts, revealing the light.
Setup 5: Pulsing Lamps with Hoppers and Comparators
This creates a flickering or pulsing light effect.
- Place Two Hoppers: Face them into each other, forming a loop.
- Place a Comparator: Place a Redstone comparator facing away from one of the hoppers.
- Connect the Loop: Run Redstone dust from the output of the comparator back to the input of the first hopper.
- Place a Redstone Lamp: Connect a Redstone lamp to the Redstone dust line.
- Add an Item: Place at least one item (like a single cobblestone) into one of the hoppers.
The item will cycle between the hoppers. The comparator detects this movement and sends out a fluctuating Redstone signal, causing the lamp to flicker on and off.
Setup 6: Pressure Plate Activated Lamps
This is great for doorways or traps.
- Place Lamps: Position your Redstone lamps around the area you want to illuminate.
- Place Pressure Plates: Place pressure plates in front of the lamps or at an entrance.
- Connect: Run Redstone dust from beneath the pressure plates to the Redstone lamps.
When a player or mob steps on the pressure plate, it powers the Redstone dust, turning on the lamps.
Frequently Asked Questions (FAQ)
Q1: Why isn’t my Redstone lamp turning on?
A1: Check your Redstone connections. Ensure the power source is active and that the Redstone dust reaches the block next to the lamp. Make sure the Redstone dust is not more than 15 blocks away from the power source without a repeater.
Q2: Can I power a Redstone lamp with a Redstone block directly?
A2: Yes, a block of Redstone is a strong power source. Place it next to the Redstone lamp, and it will activate.
Q3: How do I make the light stay on only when I press a button?
A3: A button provides a temporary signal. Simply connect the button to your Redstone lamp with Redstone dust. The lamp will turn on for a short time after you press the button.
Q4: Can I use a Redstone lamp as a Redstone signal indicator?
A4: Yes! If you have a Redstone circuit, you can place a Redstone lamp next to the Redstone dust line. When the line is powered, the lamp will light up, showing you that the circuit is active.
Q5: What’s the difference between a lever and a button for lamps?
A5: A lever stays on or off until you interact with it again, providing continuous light when active. A button provides a short burst of power and then turns off automatically.
Q6: Can I use a Redstone comparator to detect item frames?
A6: No, Redstone comparators do not detect item frames. They are designed to detect items within containers, the fullness of cauldrons, or the orientation of levers and buttons.
Q7: How far can Redstone dust travel?
A7: Redstone dust can transmit a power signal up to 15 blocks. After 15 blocks, the signal becomes too weak to power most Redstone components.
Q8: What happens if I place a Redstone lamp on top of a Redstone torch?
A8: The Redstone lamp will be powered by the Redstone torch and will emit light.
Q9: Can I make my Redstone lamps turn on at night automatically?
A9: Yes! Use a Daylight Sensor. Configure it to activate when it gets dark, and connect it to your Redstone lamps.
Q10: How do I make a lamp that turns off when it gets dark?
A10: Use a Daylight Sensor. Place it so it’s in sunlight. Connect it to your Redstone lamps with Redstone dust. You might need to invert the signal using a Redstone torch or a combination of repeaters and Redstone blocks to achieve this. For example, power a Redstone torch with the Daylight Sensor; when it’s dark, the torch will turn off, and if you have your lamp powered through that torch, it will turn off.
