CRI

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.
 
CRI

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).

Good Bulbs

Works great! There is no visible difference between these and higher priced bulbs with higher CRI ratings. The overall light in the room has not changed going from a pricy bulb to these.

I need to make sure our customers have a work area they can be comfortable with. Most lights are in hallways, but is bright enough to go beyond general lit areas.

Good quality control and design

Installing four foot lamps overhead is always difficult. Becomes more difficult if the bi-pins have jagged tips or are too long. Quality control on manufacturing these lamps is good. Easy to install.

Cool White is a great buy!

We have more than 2,000 fluorescent bulbs throughout our building and this bulb has been a saver in both value and quality. The bulb has a cool white glow which is easy on your eyes and easy on your budget. This bulb has had fewer complaints which are great from a facilities standpoint. These bulbs are long last, energy saver, and a great value. If you are looking for a great bulb for your business then look no further because this is the one.

Whenever the ballast for our older T-12 fixtures gives up, we convert the fixture to the T-8 lamps. We are tagging the T-8 fixtures with orange stick-on dots so that we know which type of lamp to carry up the ladder. We did for a time purchase lamps from a local Home Improvement store but the pin ends seemed to be jagged or the lamps were manufactured to wider tolerances and were difficult to install.

Q & A
Is a 48"- T8 able to replace a T-12 without changing ballasts? I am working with a local childrens museum moving into a new rental facility using the old style lamp fixtures and I would like make incremental changes. I have an immediate need to replace some light bulbs and want to move towards replacing light fixtures in the near future.
