I assume your reference to "IES" is the Illuminating Engineers Society standards for measuring light output.

The lumen rating of these fixtures is determined by the lamp manufactures. e.g., initial rating for the 35 watt Low pressure sodium lamp is 4600 lumens. When this lamp is mounted in our enclosure measured light output is 2.2 to 2.5 times that of a non-enclosed lamp.  Our model LPS-135LT produces approximately 10,400 lumens. The enclosure acts as an amplifier by redirecting the light in an arc < or = 180 degrees.

Approximate lumen readings are calculated in the field in the following manor: a light meter is placed at a distance at least 5 times the greatest dimension of the source ( 5 x 12.25" = 61.25 ") from the light source. The lamp is allowed to reach full brightness. Foot candles are measured at a distance of 6 ft from the fixture. We recorded a reading of 23 FC at this distance.

Mean spherical candle power ( Foot-candles x D squared where D = distance in feet from the light source ) = Lumens / 12.57.

23 x 6' squared = 828

828 x 12.57  ~/=  10,408 lumens .

Color Temperature and Color Rendering Index (CRI) Color temperature is how cool or warm the light source appears. Incandescent lamps have a warmer appearance than mercury vapor yard lights, for example. CRI is a relative measure of the shift in surface color of an object when lit by a particular lamp, compared with how the object would appear under a reference light source of similar color temperature. Commonly used as references are incandescent lamps (warm light sources) and natural daylight (a cool light source). Incandescent lamps and daylight have a CRI of 100, the highest possible CRI. The higher the CRI of the light source, the "truer" it renders color. The chart gives the CRI and color temperature of various light sources. You can see that fluorescents come in a variety of color temperatures and CRIs. If you want to use fluorescent lamps in a room that also has incandescent lamps, consider the warmer 3000K long fluorescents or 2700K compact fluorescents. Their warmer color temperature makes them a better match for incandescent lamps. Color Temperature and Color Rendering Index Consider "color temperature"--how cool or warm the light source appears--when choosing lamps. The Color Rendering Index (CRI) is a relative measure of the shift in surface color of an object when lit by a particular lamp, compared with how the object would appear under a reference light source of similar color temperature. The higher the CRI of the light source, the "truer" it renders color.
