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
78

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).
 
Color Temperature (Kelvin)
4100

Brightness (Lumens)

A rating of the initial light output of a bulb, rated after 100 hrs of operation. Lumens are a measure of how much light falls on one square foot of area, one foot away from the light source.

Average Rated Life (hr)
30000

Length (in)

Also referred to as "Maximum Overall Length" (MOL). For light bulbs, it measures the length of a light bulb, from the top of the bulb to the bottom of the base or pins and is typically expressed in inches. For light fixtures and ballasts, it applies to the total horizontal length of the item.

                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.

                          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:

                            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.

                              A:

                              If the current ballast has been changed out in the last few years and is electronic, there is a possibility that the ballast could be used with a T8 fluorescent tube. The information on the ballast itself can be helpful in determining if the ballast will work with T8 bulbs. Typically, the label on the ballast will list the appropriate bulbs to use. If the ballast has never been changed out or the label does not specify T8, you have a couple of options: a) continue using T12 bulbs until you replace fixtures or b) replace the existing ballasts with ballasts that will support T8 bulbs.

                              Check the label on the ballast. There will be a listing of the number of lamps and types of lamps that the ballast can accommodate, e.g. 3-F32T8, 2-F40T12. We are incrementally converting from T-12 to T-8 too but we're only doing it as the ballasts fail.

                              A:

                              You would have to change out the ballast due to different power requirements and also have to rewire the fixture a bit. At our business when our t12's go out I retrofit them to a T8 system. The ballasts are about $18.00 for each fixture plus bulbs and takes about 30 minutes. No need to buy the retrofit kits. Put in new ballast for T8 and then remove the redundancy that only T12 uses. All lamp holders are piggy backed together on each side of fixture. Take off the piggy back and make each lamp holder individually wired. For a 3 lamp fixture you only have to take loose one wire on each side. That's why when one T12 bulb burns out 2 T12 bulbs go off.
