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. CRI differences among lamps are not usually visible to the eye unless the difference is more than 3-5 points.

Color Temperature (Kelvin)

An expression of the hue of the light emitted, measured in degrees Kelvin. Usually expressed by a four digit number followed by (k), such as 2700k. Higher temperatures indicate whiter, "cooler" colors, while lower temperatures indicate yellower, "warmer" colors. Some common Kelvin temperature benchmarks are 2700k (warm white), 3500k (neutral white), 4100k (cool white), 5000k (bright white), and 6500k (daylight).

Great service, bulb burns out more often than larger bulbs


These little bulbs burn out much more quickly than larger fluorescent bulbs. I would not choose this particular fixture again.

Great Price


I haven't used the bulbs as yet, but they look just like the ones I have been using and should be OK. If they don't work, you;ll be the first know it!!




Good value for your dollar.


I bought these bulbs for my R.V. The bulbs work great and are a fraction of the cost of a R.V. dealer.
