Color Rendering Index is an international system used to rate a lamp's ability to render object colors. The higher the CRI (based upon a 0-100 scale) the richer and more accurately colors generally appear.

Some common Kelvin temperature benchmarks are 2700k (warm white), 3500k (neutral white), 4100k (cool white), 5000k (bright white), and 6500k (daylight).

Comments about OptoLight 75 Watt Incandescent Equivalent, ENERGY STAR Qualified. 18 Watt, 120 Volt A-Style CFL Bulb:

I installed these bulbs in five ceiling fans, one interior lamp, and use the others outdoors. On each ceiling fan there are four bulbs and the amount of light is almost too much... great bulbs with bright light. These bulbs are perfect for exterior lamps. We have two outside our house and they look good, offer bright light, and reduced cost. The lamp where we use these bulbs indoors is a bathroom light with two bulbs. These bulbs sometimes have a soft buzzing sound in this lamp when we first turn it on. Either way, these bulbs are fantastic!

      Yes, Medium is often used to refer to bulb base that is most commonly the standard size. It may also be called E26 (for it's 26mm diameter) or Edison base.
