chris j posted a thread about this a while back about looking for a submersible, Battery LED for lighting up the crystal vases at a wedding dinner. I got a catalog from Sival today that had them in it, plus some battery LED lights to put in the flowers for accent up top where the blooms are. fairly reasonably priced, but you have to buy them in bulk. Thier website is www.sivalinc.com. i searched for the old thread and could not find it. Have a great day guys- !
