General Information on Light Sources
MODULIGHTOR uses various light sources—LED’s and bulbs—and below is the
most frequently asked-for data for about them.
LED’s:
[Our LED’s are a proprietary design that was especially engineered and made for us, in collaboration
with Seoul Semiconductor.]
•
•
•
•
•
•
•
•
•
Form: the LED’s are on a nominally 12” long circuit boards—and each board greatly exceeds the
brightness of a 60 watt halogen or krypton bulb
Color Temperature: we offer two choices: approx. 2,700K -or- 3,000K
CRI (Color Rendering Index): approx. 85
Wattage: approx. 13 watts (for each LED board)
Voltage: 120 volts Note: our fixtures run on line voltage, and no separate “drivers” or
transformers are needed
Lumens: approx. 1,150 (for each LED board)
Technical specifications from manufacturer: www.modulightor.com/specs/LEDSpecsandLM80tests.pdf
Dimmer Compatibility: www.modulightor.com/specs/SeoulDimmerlist.pdf
Average life expectancy: industry standard life expectancy for LED’s is 25,000 -to- 50,000
hours—but MODULGHTOR’s LED boards have tested to significantly exceed that, under normal
operating conditions.
Halogen Bulbs
•
•
•
•
•
•
•
Color Temperature: approx. 2,800K
CRI (Color Rendering Index): 100
Wattages available: 50 -or- 75 watts
Voltage: 130 volts
Lumens - 50 watts: 750 Lm (+/- 10%, due to manufacturing tolerances)
Lumens - 75 watts: 1,200 Lm (+/- 10%, due to manufacturing tolerances)
Average life expectancy: approx. 2,000 -to- 3,000 hours (under laboratory conditions)
Kypton Bulbs
•
•
•
Color Temperature: approx. 2,900 -to- 3,000 K
CRI (Color Rendering Index): 100
Wattages available: 40 -or- 60 watts
•
•
•
•
Voltage: 130 volts
Lumens - 40 watts: 560 Lm (+/- 12.5%, due to manufacturing tolerances)
Lumens - 60 watts: 960 Lm (+/- 10%, due to manufacturing tolerances)
Average life expectancy: approx. 2,000 -to- 3,000 hours (under laboratory conditions)

A-19 Bulb
•
•
•
•
•
Color Temperature: 2,850
CRI (Color Rendering Index): 100
Wattage: 60 watts
Lumens: 870
Average life expectancy: approx. 1,000 hours (under laboratory conditions)
NOTES:
1. Please note that the above numbers are averages. LED and bulb manufacturers strive for good
tolerances—but there will, as a practical matter, always be a range. For example: color
temperatures will probably be within a range of 50 degrees (i.e.: for a color temp of 2,800K, the
actual range supplied by the manufacturers will be from 2,800K to 2,850K).
2. We use what we consider to be high-quality bulbs, made by Hybec. You can see more about
Halogen and Krypton bulbs in a brief article on our website:
www.modulightor.com/specs/HalogenversusKryptonLamps.pdf
3. Our LED boards are made by one of the leaders of the industry: Seoul Semiconductor. We
worked long & hard with them to custom engineer an LED board that would work within our
fixtures—and give great light.
4. Moreover, our LED boards eliminate some of the most troublesome aspects of other’s LED
lights: Our LED’s run on line-voltage — so there’s no separate “drivers” or transformers to hide,
detail, and install.
5. Also: when an LED light fixture fails, typically it is Not the LED emitters that are the problem.
Preponderantly: it is the drivers that are likely to be the failed element. With Modulightor’s LED
boards—which Don’t have separate drivers—that problem is eliminated. Thus a longer-life and
more trouble-free fixture is the result.
6. “Life expectancy” of bulbs (halogen, krypton, or A-lamps) is based on the point when 50% of the
bulbs have ceased to function.
