Crafting All 16 Colored Radon Lamps and the Siren Light in Alex's Caves
Radon lamps are light sources added by Alex's Caves, and every color can be crafted using Bottles of Radon. The same material also appears in the recipe for the Siren Light, a separate light block. This guide covers the recipes for all sixteen lamp colors and the siren light.
How Radon Lamp Recipes Work
Each colored radon lamp has two crafting recipes. The first is a direct recipe that produces the lamp from scratch. The second is a recoloring recipe that converts existing 
White Radon Lamps into another color.
The direct recipe follows the same shape for every color: four units of a dye of that color, four Bottles of Radon, and one 
Glowstone. The dye is drawn from the matching forge dye tag, so any item tagged as that color works.
The recoloring recipe is simpler: eight White Radon Lamps plus one dye of the target color produces eight lamps of that color. This means you can craft a batch of white lamps first and then dye them into any color you need.
Crafting Each Color
The direct recipe for every color uses four dye, four Bottles of Radon, and one Glowstone:
- White Radon Lamp: white dye x4 +
Bottle of Radon x4 + Glowstone 
Red Radon Lamp: red dye x4 + Bottle of Radon x4 + Glowstone
Blue Radon Lamp: blue dye x4 + Bottle of Radon x4 + Glowstone
Green Radon Lamp: green dye x4 + Bottle of Radon x4 + Glowstone
Black Radon Lamp: black dye x4 + Bottle of Radon x4 + Glowstone
Each of these colors can also be made by recoloring white lamps:
- Red Radon Lamp: White Radon Lamp x8 + red dye
- Blue Radon Lamp: White Radon Lamp x8 + blue dye
- Green Radon Lamp: White Radon Lamp x8 + green dye
- Black Radon Lamp: White Radon Lamp x8 + black dye
The white lamp itself can be recolored with white dye as well: White Radon Lamp x8 plus white dye yields White Radon Lamp.
Crafting the Siren Light
The Siren Light does not use a dye. Its recipe is colorless glass, a Bottle of Radon, iron, and redstone:
- Siren Light: colorless glass x5 + Bottle of Radon +
Iron Ingot x2 + 
Redstone Dust
The glass is drawn from the colorless glass tag, so any glass item tagged as colorless qualifies.
Gathering Materials
Bottles of Radon are the shared ingredient across every recipe on this page, so stockpile them before you start crafting. Glowstone is needed for each direct lamp recipe, while Iron Ingots and Redstone Dust are only required for the Siren Light. Dyes come in many forms, and because the recipes accept forge dye tags, you can use whichever dye item of the correct color you have on hand.
If you plan to make several colors, crafting White Radon Lamps in bulk and recoloring them is an efficient path, since each recoloring recipe turns eight lamps into eight lamps of the new color. For a single lamp of a specific color, the direct recipe with Bottles of Radon and Glowstone works just as well.
