We have a number of different globes.
LED light bulbs don't have filaments. Instead, they use special materials (called 'solid-state semiconductors') that emit light when electricity passes through them. LED light globes have a very long life (20,000 hours), generate almost no UV or heat, and are very efficient. They are the new in-thing in the light world and are very cost effective. The one downside with LEDs, however, is that are directional making them great for task lighting but not for general room illumination.
The candle light bulb is elongated in shape, and is designed for decorative purposes to mimic a real candle.
LED tubes are the new replacement to fluorescent tubes. They are mercury free, directional (which can be a disadvantage), do not burn out by turning them on/off, are more efficient, do not flicker, have a large lifespan and are more shatterproof.
Compact Fluorescent Globes (also known as Compact Fluorescent Lights, or CFLs) are also very energy efficient and last 10 times longer than normal light globes. Unlike fluorescent tubes, they are quiet, instant-on and have a warmer tone. They can be used anywhere you would use a normal light bulb. Their downside is that they are prone to decreased life when you use them in short burst and are not as good in colder temperatures.
Fluorescent tubes are sealed glass tubes containing an inert gas (usually argon) and a tiny drop of mercury. They save about 70% of the energy used by normal light globes and last longer as well. However they are noisy, can flicker and their colour is harsh.
Vintage filament globes (also called antique light bulbs or Edison light bulbs) have clear glass envelopes and beautifully designed, intricate filaments. They are highly decorative and emit a very flattering warm light. They have become extremely popular in homes, restaurants and bars. They are often hung with the naked globe showing.
LED globes have until recently looked fairly unconventional. LED vintage filament globes have changed all that. They look just like their incandescent vintage counterparts thanks to a unique new LED technology.
Infrared globes are those that emit heat rather than light.
Industrial globes are generally used in transparent or caged light fixtures.
