"On our Cerno journey, we continue to evolve as designers and craftsmen. The Penna is a celebration of us drawing and reflecting on our last ten years. This design is an embodiment of all the lessons that we have learned from designing and building thousands of lights. This fixture balances utility and sophisticated beauty well. The walnut, brass, and leatherwork in concert to compose a modern form with materials that have been used for thousands of years." — Nick Sheridan, Designer Features: Penna 40 dimensions: 40.5" x 7.7" , 2.3" Penna 64 dimensions: 64.5" x 7.7" x 2.3" Materials: solid wood, polymer, brass, leather Penna 40 weight: 7 lb Penna 64 weight: 10 lb Light source: integrated LED Penna 40 Light output - total: 15300 Lumens (source) Penna 64 Light output - total: 2550 Lumens (source) Light color: 2700 K Color accuracy: 90+ CRI Penna 40 power usage: 21 W Penna 64 power usage: 35 W Dimmable Drop length field adjustable: 10" min, 8' max Suitable for a sloped ceiling Specifications subject to change Wood grain will vary How it is Made Metal Finish: Lamping: 2700 K LED (Soft white)or 3500 K LED (Bright/Cool white) Driver: 120-277 V AC input voltage, 0-10 V dimming, TRIAC and ELV dimming at 120 V AC only Dimensions: Penna 40: 40.5" x 7.7" x 2.3" Penna 64: 64.5" x 7.7" x 2.3"
