has a wide selection of bulbs. I use the Philips vision plus (+50) as they have about the most light from a standard wattage bulb. For the fogs, a yellow bulb will do best in fog, and a blue bulb will do worst - most scatter and poorest penetration. If you are only using them as decoration instead of serious fog bulbs, the above site also has blue bulbs.
