Just a reminder. At the end of this year it will be illegal for stores in the US to sell 100watt bulbs. If you have trouble reading with the new fangled twisty bulbs you had better do some planning. I'm stocking up on enough 100 W and 50/100/150 watt to last me for then next 30 years. I'm all for conserving, but I've tried reading with the twisters and I just can't get enough light out of them no matter if they are rated for 100 watts.
