You wanna know where to get this, that, or some other light bulb? Or where to get them for less? You may have come to the right place, but probably only if you are in the USA. Most suppliers mentioned here are in the USA. Light bulbs for residential use are usually designed for 120 volts. The AC line/mains voltage and frequency is not the same in all countries.
Lowest price on Philips light bulbs - Sears and Home Depot, except many Sears stores no longer sell regular light bulbs and Home Depot is selling fewer Philips compact fluorescents than they used to.
Lowest price on GE light bulbs - Target, next best is Wal Mart. Home Depot has a few GE models.
Best selection of these - Lowes with Home Depot a close second.
Store brand light bulbs at supermarkets and drug stores are normally decent quality (usually General Electric, sometimes Sylvania) light bulbs, as long as the life expectancy and lumen light output on the package resemble those of name brand ones. (Note that if you compare Soft White with Standard light bulbs, the Soft White ones will be rated for slightly lower light output.)
High prices - Rite Aid, with CVS not much lower.
Most 130V bulbs have even further compromised light output due to having a cheaper filament design, longer design life expectancy, and/or or a vibration resistant filament design. Good sources are online sellers such as bulbs.com.
At a given line voltage, expect life about 2.5 times that of 120V lightbulbs.
If the bulb in your refrigerator has nothing plastic within about 2 inches above it, and one of those 40 watt appliance bulbs will fit, use that. Beware that K-Mart seems to be testing the waters with inflationary pricing of 40 watt appliance bulbs.
If an appliance bulb is OK AND nothing will drip on it AND you always close the door gently, use an ordinary 25 or 40 watt light bulb.
Beware, if you see any 60 watt ones, avoid them unless you are sure the much higher heat output is OK. 40 watt and smaller tubular fridge bulbs have a vacuum, 60 watt 120 volt ones are gas filled and the gas conducts heat from the filament to the bulb surface.
One particular bulb in high demand is the 300 watt tubular "Type J" halogen bulb for those torchiere lamps. Type "J" bulbs are also Type "T" (tubular) ones, so it is OK to use a similar-looking bulb that fits if it comes in a package saying "Type T" if the fixture has a label indicating requirement of "Type J". Do not use a 500 watt bulb even though in some stores, the 500 is cheaper or the only one there. A torchiere lamp rated for use with no more than a 300 watt bulb is a fire hazard with a 500 watt bulb. The wiring, especially where it connects to things, does not reliably stay cool enough with the higher current. The switch and any dimmer circuitry also do not reliably handle the higher current.
As for those little 20 watt bulbs? My favorite is Sylvania, but GE and Philips are at least close. In my experience, the Radio Shack ones are much dimmer and less white in color.
Sylvania brand ones are available at good prices at Lowes.
You will usually find a few to maybe a fair variety of General Electric ones, especially the spiral ones, at Target and probably also at Wal-Mart.
Many people have bad comments on Lights of America. My experience is limited to the extent of possibly being a too-small-sample, but it has not been good. Lights of America may be better with spiral ones of wattage other than exactly 25 watts, except I have usually found their light output claims to be slightly overstated.
I have my experiences, test results, and some Consumer Report's test resultshere.
I would avoid compact fluorescents from dollar stores other than Dollar Tree. I have yet to see any other dollar store compact fluorescents, mostly with claims to replace incandescents of wattage anywhere from 50 to 125 watts, to actually outshine or even fully match the output of 40 watt "standard" incandescents. This is after testing 22 "brands" and 72 "models"! Furthermore, most dollar store compact fluorescents have a bluish white "cool daylight" color, even many in packages that say "Sun Lighting" and many that come in packages that say "soft warm white light". Many that actually have a "warm white" color have a very purplish "off" color and low color rendering index.
As for where to get them? Try home centers and electric/lighting supply shops of the kind that contractors go to, possibly online sellers.
But what what you really want are the fluorescent type. They work a lot better. The best prices are at Home Depot. Expect to pay around $12 to $16 for a bulb, regardless of wattage and size. A bulb in a fixture will cost more, and you can also get this at Home Depot.
K-Mart and Wal-Mart sell a few fluorescent style blacklights for approx. $22. One is a 22 watt 8-inch circular tube with a ballast-adapter to fit it in a regular light socket. The other is a 2 foot long "stick" fixture with a 20 watt bulb. Both appear to have cheap or even resistor ballasts, so be prepared for power consumption around 36-40 watts, more heat than usual, and a little less UV/light than usual for the bulb's rated wattage. I believe they now also sell a 15 watt fixture with a real ballast.
You can get fluorescent style blacklights at Spencer Gifts, which is in some malls. Check your phone book. Prices will be higher and quality may not be as good as you can get from Home Depot.
I have doubts on the quality of the"Derma Spec" 4 watt units that have been available from surplus sellers. There is an obnoxious feature of the 4 watt "Derma Spec" fixture - an automatic shutoff after 1 minute. Go here for the hack to defeat this.
You can get blacklights from Edmund Scientific, but prices are higher here.
You can get these from American Light (see below).
You can get blacklights, incandescent or fluorescent, at some
college/university bookstores. One brand that I have seen is "Mr. Light".
They even have a 13 watt compact fluorescent screw-in blacklight bulb.
Just beware that one "Mr. Light" fixture that looks somewhat like a blacklight in the color of the glowing bulbs is not a blacklight and it has very minimal blacklight effect and nothing on that fixture nor its package claims that it is one - it is merely a purple decorative light.
Lava lamps are now available at Radio Shack and some other places. Some college/university bookstores have some decorative lamps.
High pressure sodium lamps will usually cost $20 to $30 for wattages 150 watts or less, and a little more for higher wattages up to 400 watts.
Metal halide lamps of 50 to 400 watts are available at Home Depot and Lowes and usually cost around $30-35.

Pureland Supply, a supplier
of specialty lamps such as microscope lamps, photographic lamps,
photoflash lamps and large flashtubes, etc. They also supply the usual
mercury, metal halide, and sodium lamps as well as ballasts.
Projectorquest, a source of projector lamps, mostly for projector TVs and monitors, digital projectors, and the like.
When nothing else can do, there are some desperation measures: Look in long-established appliance repair shops. Look in thrift shops for these bulbs and room-deodorizing lights with these bulbs. WARNING - be prepared to be disappointed. Be prepared to find some other way to get your ozone or your shortwave UV.
