How to Make a Laboratory in RimWorld 1.6: Room Role, Research Speed and the 80% Penalty

There's no Laboratory button in RimWorld. A room becomes a laboratory when its lab benches outscore everything else in it, and since 1.6 a research bench outside a laboratory works at 80% speed. This video covers the build order, how room roles are scored (+60 per lab bench, +27 per workshop bench, +28 per stove or butcher table, and 100,000 for any bed), and every factor that multiplies research speed: bad temperature below 9°C or above 35°C (×70%), open sky (×75%), open ground with no walls (×56%), darkness (×80%), room cleanliness (75% to 115%), sterile tile vs. steel tile, the hi-tech bench, multi-analyzer placement (8 tiles center to center, line of sight, powered), and the bookcase reading bonus (up to +20% at 145 books). Ends with a side-by-side: 32.7 vs 10 research points per hour for the same pawn.
