About this Mod

⚡ MekaLights ⚡

Smart, energy-powered area lighting for Mekanism.

Stop torch-spamming your caves, factories and farms. Place one MekaLight Block, feed it Mekanism power, pick a shape and range — the machine floods the area with invisible, full-brightness light emitters. One block, up to a 48-block radius, zero clutter.

⚠️ Alpha — fully playable, but balance and features may change. Bug reports welcome!

Features

💡 Five light shapes:
- 🌐 Sphere — full 3D volume, ideal for caves and big rooms
- ⭕ Disc — flat layer for floors, fields and mob-proofing
- 🔦 Cone — real spotlight: aperture 15°–90°, 6 aimable directions
- 🛕 Dome — half-sphere, aimable up (dome) or down (bowl)
- 🛢️ Cylinder — vertical column with adjustable height (4–32 blocks)
⚙️ Clean Mekanism-style GUI — shape side panel with pixel icons, range, aperture, direction, height and live energy readout
🔋 Mekanism energy — cost scales with range; Energy Upgrades reduce consumption
👻 Invisible ghost emitters — no collision, build right through them, cleaned up automatically when the machine is broken or unpowered
🛠 Debug view (per machine) — green wireframe outline of the configured area, works even before powering on. Perfect for planning
🔍 Jade support — status and energy usage on hover
🌐 Multiplayer ready — built and tested for servers
