Lamp — Factorio Production Calculator
Lamp is crafted in the assembling machine in 0.5 seconds, producing 1 per craft from 1 × Electronic circuit, 3 × Copper cable, 1 × Iron plate. At 60 per minute you need 1 assembling machine, and the chain behind it draws on 2 raw resources: copper ore, iron ore.
Production chain for 60 Lamp / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Copper cable | 360 | 3 | Assembling machine |
| Copper plate | 180 | 9.6 | Furnace |
| Iron plate | 120 | 6.4 | Furnace |
| Lamp | 60 | 1 | Assembling machine |
| Electronic circuit | 60 | 1 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Copper ore | 180 |
| Iron ore | 120 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Lamp recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 0.5 s | 1 | Electronic circuit × 1, Copper cable × 3, Iron plate × 1 |
What the whole chain needs
60 lamps per minute pulls in 4 intermediate products, and the whole tree comes to 21 machines across 2 machine types, fed by 2 raw resources. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 180 per minute, which is 0.2 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.
What uses lamp
No base-game recipe consumes lamp — it is an end product. Once you build it, the chain stops here, which makes it a good target if you only want to size the sub-factory that feeds your mall.
What lamp is made from
- Electronic circuit — 1 per craft
- Copper cable — 3 per craft
- Iron plate — 1 per craft
FAQ
How many assembling machines do I need for 60 lamps per minute?
1 assembling machine. One at standard speed produces 60 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does lamp take?
At 60/min the chain consumes 180 copper ore per minute, 120 iron ore per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Machine counts assume bare machines at standard speed. Recipe data comes from the game's own prototypes (PlayerCalc, Factorio 2.0 base game). Not affiliated with Wube Software.
