ANSWER:One of the byproducts of Mercury vapor and argon gas is luminescence or light. The bulb is full of gas and when you turn on the switch, the starter will fire an electrical charge on both ends of the bulb exciting the gas inside and a small amount of mercury emits vapor and the gas molecules collide and excite more molecules nearby until the entire contents are excited. This makes the bulb get brighter until it reaches its maximum brightness. The white phosphorous coating inside the bulb increases illumination. If It didnt have this powder coating, It would be a black light. In cooler temperatures, you can see the pulses of the light as it goes from one end to the other in waves. Tha average bulb reaches full brightness in about 15-20 seconds on average.

What is the difference between aquarium fluorescent lighting and household fluorescent lighting besides price?

Since fish do not carry out photosynthesis, they do not really care about your choice of light. Incandescent lights will however produce a lot of heat and can make the water near the lights really warm. Since the fluctuating water temperatures can be harmful to your fish, fluorescent lights are a safer choice. They are a bit more expensive, but will on the other hand cut money off your electricity bill. Fluorescent lights are also more similar to sun light and will make the fish look more colorful and brilliant in the aquarium, and aid in the health of invertebrates.

I think that you may be confusing fluorescent tubes with neon tubes. Fluorescent tubes use a phosphor coating on the inside of the lamp which is in a limited spectrum.

Do fluorescent lights use less power if left on?

Short answer is no. Old fluorescent fixtures use to have ballasts that required considerable energy to start and warm up, if the light was switched on and off frequently then it would have been better just to leave it on, however this limitation has been solved since the early 1980's. You are doing yourself no favors by leaving a modern florescent light on

What is the difference between daylight fluorescent and warm white fluorescent?

The light from a "Daylight" type looks brighter to the eye than "Warm White". The "Daylight" type is supposed to make colors of things (clothes, furniture, etc.) look more natural, as if they were outside in daylight. The "Warm White" type is supposed to be more restful for our eyes when we have to live or work for long periods using artificial lighting. It also is supposed to look more like the light from conventional incandescent filament lamps.
