Rigolo was designed by Berkeley-based Terry & Terry Architecture, who say the lamps were sourced at Arkitektura in Situ and chosen not only for their visual drama but for the warm, even light they produce. They were hung at random heights to fill the wood-trussed, sky-lit space.
Bulb 85 does in fact contain 85 long-lasting low-wattage bulbs in each fixture, and Alex Terry tells us that someone at Rigolo climbs a very tall ladder every six months or so to change the handful that have burned out.
The lamp is reputed to be very heavy, so don't try this at home. But it seems like it should be easy enough to DIY your own lighter version, say, a "5 Bulbs Chandelier," and hang it above your dining room table.
