Lamps are blocks that glow and supply light when a Redstone signal is supplied. This makes it a viable building material for Redstone displays that need to be visible in the dark or coloured indicator light.
Note that Red Power Lighting Blocks don't emit coloured light. While the block itself has a color, the light it emits is normal white light.
The possible colours of the block are White, Orange, Magenta, Light Blue, Yellow, Lime, Pink, Gray, Light Gray, Cyan, Purple, Blue, Brown, Green, Red and Black.
This is an example recipe since the Lumar color can change.

If you break a lit lamp with an item that has the silk touch enchantment on it then it will drop an item called "unnamed". It will turn into a white lamp if placed.
