Improve on the itty bitty Book Light? No way! Unless you happen to be Zelco, the creator of the original, classic, award-winning itty bitty booklight -- the smallest, lightest, brightest, best-selling booklight of all time. So, it was up to Zelco to create a new, better 'itty bitty' Book light. It's Volume 2. Smaller, lighter and brighter than the original -- and with a new high - tech look, it promises to be a runaway bestseller with a whole new generation of readers. Even the storage book it comes in is smaller, more compact, than the original. Better for today's faster moving, mobile reader. If you loved the fast selling classic original you're really going to love Volume 2. The package includes a 240 voltage adapter, battery case (4 "C" batteries not included) and an extra bulb.
