Query: useless

The Hakuba LB 810 light box is useless without a plug in. Your ad states it can be used with ac or batteries - the batteries are not included. It does not state anything about an ac cord or adapter as not included. When I checked about the adapter-it stated it was not available. How am I to use a light box without a plug in. Don't tell me to use the batteries. The light box takes 6 Ds and they are heavy. Besides,most electronic devices use batteries or can be pluged in. It may be going back. Tom Buonomo
