thank you for this interesting approach, i wonder what are the regulations on this subject, do the European States will taxe soon strongly the old technology bulbs in favor of the fluorescent bulbs ; do you think that the market will keep the 2 ? -may be it’s already the case –
any way, I am waiting for your next post about “how green are they” ; in my case i have some douts and would be interested to stock some old ones for my home …
