I rewired a similar panel. The D.C. bulbs were 28 volt and the ac bulbs were 250 volt. Using 12 vdc and 120 vac bulbs, the panel bulbs were way too bright. The dc bulbs are red and the ac bulbs are orange. We're in the Bahamas till May. If you can wait, I'll be glad to send you a few with clips to try them out.
