J.S. Cotney, Inc. (http://www.cotney.com) is a manufacturers representative for lighting companies nationwide. This is a brief presentation that highlights induction lighting technology and the benefits of using induction. Also covered are basic lighting definitions.

3. ● Induction lamps do not use filaments or electrodes
● Light is generated from phosphors on the glass
inside the lamp by means of electromagnetic fields.
● Electromagnetic fields (rather than filaments) give
induction lamps extremely long lives

5. ● Unmatched durability
● Extremely long life (100,000 hours)
● Instant ignition
● No flickering or cycling
● Performs well in extreme cold
● Superior color rendering index (CRI) > 80

6. ● No glare
● Vibration resistant
● High energy efficiency/efficacy
● Quality white light
● Mature, proven light source
● Virtually maintenance-free

7. Lighting Definitions
Lumens per watt is a measure of efficiency. It is the amount of light
a source gives off per watt.
Technology Lumens per Watt
Induction 65-76
Metal Halide 60-100
High Pressure Sodium 45-110
Low Pressure Sodium 80-180
Mercury Vapor 13-48
Incandescent 11-15

8. Lighting Definitions
CRI (Color Rendering Index) is a measurement of how a light source
matches color to sunlight at high noon (100 CRI) on any given day.
Technology CRI
Induction >80
Metal Halide 75-80
High Pressure Sodium 21
Low Pressure Sodium 40
Mercury Vapor 45-65
Incandescent 90+

9. Lighting Definitions
Color temperature is the color of a light source. 2700 degrees
Kelvin is very orange; 6500 degrees Kelvin is very blue.
Technology Color Temperature
Induction 2600K-6000K
Metal Halide 3000K-4300K
High Pressure Sodium 2100K
Low Pressure Sodium 1800K
Mercury Vapor 4000K-5900K
Incandescent 2800K

10. Lighting Definitions
Rated life is determined when half of any given light source fails to
operate, or when that light source declines to 70% its original output.
Technology Rated Hours
Induction 100,000
Metal Halide 15,000
High Pressure Sodium 12,000-24,000
Low Pressure Sodium 10,000-18,000
Mercury Vapor 12,000-24,000
Incandescent 1,500

11. Lighting Definitions
● Power Consumption is the amount of watts that both a driver
and lamp collectively consume.
– HID systems can consume 10%-20% of their total power,
just in their ballasts.
– Induction consumes as little as 2% of their total power.

12. Lighting Definitions
Photopic is how the human eye responds to light during the day,
whereas Scotopic refers to how the eye responds to light at night.
Technology IES Photopic/Scotopic
Multipliers
Induction 2.14
Metal Halide 1.4
Pulse-Start Metal Halide 1.4
High Pressure Sodium .6
