EU has decided to ban the production on "old fashioned" light bulbs; starting september 1 this year (starting with 100 watts and above... then gradually outfacing all bulbs in the next couple of years.. We use 150watt lightbulbs in several of our enlargers. What should we do? hoard as the sweedish people seem to do? or is there a subtitute been made for all of us with this problem? As the bulba are opaque (?), maybe it doesn't matter what is inside the glass, as long as the power is sufficient? Any light (sic.) on this? what do you do?
