Confused about replacement bulb terminology (pictures, lights, design, table)

[user-3489_j65]

The packages for CFL and LED bulbs often use the terms "recessed fixtures" and/or "totally enclosed luminaries". If the terms are not on the packaging they are sometimes found on the bulb itself when it is too late to know the bulb may not be suitable for my intended use. Is it possible for someone to give me common examples of these 2 types of lights? Thank you.

Why not just tell everyone what your "intended use" is and you'll probably get plenty of suggestions as to which bulb/fixture/lumen/wattage/voltage/candle power/etc. to use.

I started to type my reply but found better explanation here:

Heat is the enemy of LED light bulbs. Thats why not all LED bulbs are designed to use in enclosed fixtures. (Bulbs that are totally enclosed in a glass fixture can't cool off. )

This is recessed light fixture. Note that the bulb isn't totally enclosed. It can "breathe " and cool off

If you are in a store, in most cases it's perfectly OK to open the package to see and even try the bulb.
If you order online, there are usually additional pictures that will show you the best use for that bulb.
