Thanks once again to everyone for your help. I received my shipment from Replacement Bulbs today, only one week after placing the order, a track record for a package handled by Greek and US post! I wanted to confirm that both Don's Bulbs and Replacement Bulbs, mentioned by Clogz and Doughowk, have amazingly detailed databases of bulbs. I went with the latter due to price, $3.00 per bulb. I ordered six which should keep me going for a while in spite of local power fluctuations.
Sincerely,
James
