I was trying to replace some PL-13 bulbs on one of my smaller tanks yesterday, and was displayed to find that Lowes no longer even carries the ballasts, and that the bulbs themselves were only available in warm white. So I picked up one of the 27 watt "99 cents" daylight bulbs and have it in a pendant fixture over the tank. I would imagine that one could come up with a 2-light pendant over a 10 that would look pretty slick. - Erik -- Erik Olson Sent from my crusty old Linux box erik at thekrib dot com _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
