The average price of replacing a UV bulb will depend on the size required. UV bulbs are used for many purposes, including tanning and reptile care so sizes do vary greatly.
Ultraviolet (UV) light bulbs emit UV rays.
A fluorescent bulb primarily absorbs ultraviolet (UV) light energy. Inside the bulb, electricity excites mercury vapor, producing UV light, which then interacts with a phosphor coating on the inside of the bulb. This interaction converts the UV light into visible light, allowing the bulb to illuminate.

Fish tank light bulbs do not give out any significant amount of UVB, you really need to get a real UVB reptile bulb. You can get them at a great price online at www.bigalsonline.com. I attached a link to the UV bulb section
When looking to buy a 75W replacement UV bulb then there are several sites on the internet that sell them. There are sites such as Amazon, Maplin, eBay, Tesco and Reptile UV who all offer Ultraviolet light bulbs and lamps for sale.
That all depends in the resistance of the filament in the bulb there is not enough info in the question
If it emits UV, yes...tanning beds do
Not the average one, but they do have special ones (they are found in tanning beds). Those are essentially fluorescent tubes, but without the coating to convert UV into more visible light.
red bulb for the night time and white bulb pluse uv tube for the day.
NOOOOO
The element in a fluorescent light bulb that absorbs UV light and releases visible light energy is a phosphor coating on the interior surface of the bulb. When UV light hits the phosphor coating, it emits visible light, creating the illumination we see in fluorescent bulbs.
The dark black incandescent type UV bulbs will work as they actually get hotter than the equivalent standard incandescent bulb of the same wattage, but the compact fluorescent type UV bulbs run too cool.
