The letters stand for a specific characterisitic of the bulb

PAR stands for Photosynthetically Active Radiation (PAR) Units and the number is a measure of the units. PAR lamps are Halogen lamps and also contain an internal reflectorized coating as well as a prismatic lens to maximize light output. PAR lamps deliver a stronger punch of light than R lamps with better beam control.

AR means Aluminum Reflector, used for accent and display lighting (spots in essence)

R means reflector, again a more focused light or a spot.

T refers to Tri-phosphor flourescent lamps, which have an improved red light emission compared to Halo phosphor (H) lamps.

FS refers to full spectrum, ie. the emitted light ranges across the whole visible spectrum

A-lamps require reflectors to effectively control and distribute light. These are the old-fashioned standard lightbulb.

R and BR lamps contain an internal reflectorized coating that creates distribution patterns ranging from spot to flood. These lamps are well suited for accenting and wall washing where directional control is required.

Every time you change the type of light bulb you will change the effect of the lighting. You won't get exactly the same effect with CFLs as you do with incandescent or halogen bulbs, but it may be equally satisfactory.

According to Cooper lighting, modern CFLs will work in many modern recessed fixtures as long as there is enough airflow so it is really a question of how much airflow occurs in your recessed fixture - do they vent to the attic or are they fully enclosed in a ceiling?.

There are even dimmable CFLs now.

EnergyStar recommends installing qualified CFLs in fixtures that are used at least 15 minutes at a time or several hours per day. The best fixtures to use qualified CFLs in are usually found in the following areas of your home:

family and living rooms
kitchen
dining room
bedrooms
outdoors

Matching the right CFL to the right kind of fixture helps ensure that it will perform properly and last a long time.

For example:

CFLs perform best in open fixtures that allow airflow, such as table and floor lamps, wall sconces, pendants, and outdoor fixtures.

For recessed fixtures, it is better to use a reflector CFL than a spiral CFL since the design of the reflector evenly distributes the light down to your task area.

If a light fixture is connected to a dimmer or three-way switch, you'll need to use a special qualified CFL designed to work in these applications. Make sure to look for CFLs that specify use with dimmers or three-way fixtures.

Choose a qualified CFL that offers a shade of white light that works best for you. For example, while most CFLs provide warm or soft white light for your home, you could choose a cooler color for task lighting.

To choose the qualified CFL with the right amount of light, find a qualified CFL that is labeled as equivalent to the incandescent bulb you are replacing. Light bulb manufacturers include this information right on the product packaging to make it easy for consumers to choose the equivalent bulb. Common terms include "Soft White 60" or "60 Watt Replacement."

You should also check the lumen rating to find the right CFL. The higher the lumen rating, the greater the light output.
