Mekanism Lights

If you hate putting a light source every 3 blocks, this mod is for you. It adds Mekanism style lights that light up a whole area around them, with range depending on tier, and a Light Multiblock that lights an even bigger area depending on its size.

Standard Light

Four tiers, crafted from the High Wattage Bulb:

Tier	Range	Power use	Energy buffer
Basic	8	120 J/t	10 kJ
Advanced	12	240 J/t	40 kJ
Elite	16	360 J/t	90 kJ
Ultimate	20	480 J/t	160 kJ

• Accepts Mekanism Energy Upgrades: with all 8 installed it uses a tenth of power
• Upgrade it in place with Mekanism Tier Installers. It keeps its stored energy, the battery in its slot, on/off state, redstone mode, security and upgrades
• Turn it on/off by sneak right click with an empty hand (respects Mekanism security), or with redstone
• Light only reaches places it should, it doesnt go through walls. Grass, flowers, torches, rails, etc. don't block it

Light Multiblock

Box from 3x3x3 up to 9x9x9 that lights a whole area.

• Floor: Light Casing, with at least one High Wattage Input Port anywhere on the shell to power it
• Walls and top: Mekanism Structural Glass
• Inside: completely filled with High Density LED Arrays

Size	Max range
3x3x3	32
5x5x5	64
7x7x7	96
9x9x9	128

• Set the range in the GUI: left click the buttons to step by 1, right click to step by 16
• Energy use and the energy buffer grow with the range, the LED count and the size of the structure
• Sneak right click any casing with an empty hand to turn it on/off, redstone works on any block of the shell
• The GUI shows the size, LED count, range, if its on or off

How the light works

Lights place invisible light blocks every few blocks inside their range, only in air and only where there is a line of sight back to the light. The spacing and how often the light updates can be configured in config.

• Light blocks dont show up on maps, cant be pushed by pistons, don't stop saplings from growing, and are never placed next to obsidian, so they cant block a nether portal
• Light blocks whose light is gone remove themselves within a minute or two after the area loads
• tags: thanasmekanismlights:light_passable, thanasmekanismlights:light_blocking, thanasmekanismlights:light_avoid

Config

Usually (%appdata% -> .minecraft -> config -> thanasmekanismlightsconfig.properties)

Setting	Default	What it does
STANDARD_LIGHT_ENERGY_PER_TICK	120	Standard Light power use in Joules per tick, times the tier (Basic 1x, Ultimate 4x)
BASIC_STANDARD_LIGHT_RANGE	8	Range of the Basic Standard Light
ADVANCED_STANDARD_LIGHT_RANGE	12	Range of the Advanced Standard Light
ELITE_STANDARD_LIGHT_RANGE	16	Range of the Elite Standard Light
ULTIMATE_STANDARD_LIGHT_RANGE	20	Range of the Ultimate Standard Light
RECALC_LIGHT_SWITCH	false	Recalculate light only when the light is switched on (much better performance)
RECALC_TICK	10	Ticks between light updates (more = better performance, slower light changes)
SPACER	2	Blocks between light blocks (bigger = bigger gaps, worse coverage)
MULTIBLOCK_RECALC_TICK	10	Ticks between multiblock light updates (raise this first if a big multiblock causes lag)
MULTIBLOCK_SPACER	2	Blocks between the multiblock's light blocks
MULTIBLOCK_MAX_RANGE	128	Hard cap on multiblock range
MULTIBLOCK_RANGE_PER_SIZE_STEP	16	Range per size step, a box of side S reaches (S - 1) times this
MULTIBLOCK_ENERGY_BASE_PER_RANGE	50	Multiblock Joules per tick per point of range
MULTIBLOCK_ENERGY_PER_LED_PER_RANGE	1	Extra Joules per tick per point of range, per LED array
MULTIBLOCK_ENERGY_PER_VOLUME	50000	Multiblock energy buffer per block of its volume
MULTIBLOCK_AMBIENT_SOUND	true	Quiet hum from the multiblock while it runs

Changing a range or the spacing in the config also changes lights that are already placed. Updating from 1.4: BASIC_LIGHT_CONSUMPTION is no longer used. If you changed it, put the same number into STANDARD_LIGHT_ENERGY_PER_TICK.
