Design by Piet Hein originally sketched in 1931
The RA lamp series uses isolux surfaces — mathematical shapes Piet Hein developed to distribute light evenly with minimal glare. That’s why even large versions like the RA 400 feel visually calm and functional while still being decorative design classics.
Pendant version (Ø 400 mm): Piet Hein also produces a RA 400 pendant in red metal finish. It features two layered metal shades that distribute light without glare, a long textile white cord (≈3 m), and an E27 max 75 W socket
