Well for sure stock up.
I tend to go through a ton of bulbs... so I am hunting down the regular ones while I can also. I had a tenant over the summer that was doing a huge job for Com Ed. They are pushing these CFL's and offering HUGE discounts to businesses to convert. He did my facility for free. Over 100 bulbs, ballasts etc. He taught me quite a lot about these bulbs and the mercury inside. They have to be disposed of in a proper way also or they will leach the mercury into the ground. In other words... they are poison. Mercury seems to be a fave for the ptb to use on us.
