I ordered some yellow CFL lamps to help boost melatonin production in the ferrets in the ferret room and so I can work in there without a flashlight. The light produced looks exactly like that of a CFL bug light which is also made to block the blue spectrum. Is there any real difference in the special bulb that is worth the increased cost (plus shipping) or can we just use bug lights around the ferrets and see the benefits at a much lower cost? Thanks for any info. Carol J. Owens Ferret Friends, Inc. Tucson AZ [Posted in FML 6791]
