TWISTED PAIR EXTENSION
Calculating the wattage of the LEDs to be installed
The following method can also be used to calculate the load on only one power supply or individual sections of the
architectural lighting project. Please note that the “watts per module" value must be taken from the specification sheet of
the appropriate product.
wattage = number of modules X watts per module
total wattage = wattage of module type 1 + wattage of module type 2 + (…)
Applying the distance factor if applicable
If the power supply is installed away from the LEDs, use table 1 below to apply the appropriate distance factor to the
wattage of the power supply.
Table 1: Distance Factor for Twisted Pair Extension
The distance refers to the distance between the power supply and the first LED module.
Watts available for LEDs = wattage of the power supply X distance factor
The values given in table 1 are usually enough to do proper distance factor calculations. If the distance between the power
supply and the first LED module falls between two columns in table 1, it is possible to calculate the distance factor using
linear interpolation.
Target distance factor =
(target distance –length 1) (distance factor 2 –distance factor 1)
+ distance factor 1
(length 2 –length 1)
Example (target distance of 88 feet with LMPS-750)
Target Distance factor =
(88 –75) (0.69 –0.73)
+ 0.73 = 0.71

Calculating the number of power supplies your project requires
When using a distance factor use the “watts available for the LEDs” instead of the “wattage of the power supply”. Round
the result up to the next integer.
Number of power supplies = total wattage / wattage of the power supply
Please note that HEICO lightingTM’s LMPS-350 and LMPS-DC350 have a wattage of 35 watts and the LMPS-750 has a wattage of 75 watts.
Calculating the system wattage
Take the number of watts of LEDs at the output of each power supply and use the appropriate power curve on figure 8 (p.17)
to determine each power supply’s consumption. The average output power can also be used if the load is distributed evenly
throughout the power supplies.
Calculating the total system power consumption
The total system power consumption equals the sum of the power consumption of each power supply.
Calculating the cost of electricity for a year for the complete architectural lighting system
Price of electricity per year =
Total system wattage X hours of usage per day X 365 days per year X price of electricity per kW/h
1000
Please note that “Price of electricity per kW/h” is according to your local electricity rate.
Determining the system efficiency
Due to the high frequency nature of the output of the LMPS power supplies, the input power factor must be used to determine
the system efficiency. Take the input watts of each power supply and use the appropriate power factor curve on figure 9
(p.18) to determine the system efficiency.
Additional Considerations
Distribute the load equally between multiple power supplies. This ensures a uniform level of light across the power
supplies.
Contact HEICO lightingTM for more details about power consumption calculations when using a distance factor.
All calculations are theoretical. Measurements made on the real life installations can differ from the calculations.
EXAMPLE
Modules : 95 PolyoptikTM 20˚X20˚ 3000K & 20 PolyoptikTM 180˚X180˚ 3500K
Power supply : LMPS-750 (75W)
Twisted pair extension : 50 ft
Distance factor at 50 ft: 0.77
Wattage 1 =
95 PolyoptikTM 20˚X20˚ 3000K X 1.35 watts
= 128.25 watts
Wattage 2 =
20 PolyoptikTM 180˚X180˚ 3500K X 1.35 watts
= 27 watts
Total wattage =
128.25 watts + 27 watts
= 155.25 watts
Watts available for LEDs = 75 watts X 0.77 = 57.75 watts/power supply
Number of power supplies required = 155.25 watts total/57.75 watts/power supply = 3 LMPS-750
Therefore, to distribute the load equally, install 38 modules on each of the first 2 power supplies and install
39 modules on the third power supply for the total 115 modules.
Total system power consumption = 63 watts + 63 watts + 65 watts = 191 watts

Take the number of watts of LEDs at the output of each power supply and use the appropriate power curve on figure 8 (p.17)
to determine each power supply’s consumption. The average output power can also be used if the load is distributed evenly
throughout the power supplies.
Calculating the total system power consumption
The total system power consumption equals the sum of the power consumption of each power supply.
Calculating the cost of electricity for a year for the complete architectural lighting project
Price of electricity per year =
Total system wattage X hours of usage per day X 365 days per year X price of electricity per kW/h
1000
Please note that “Price of electricity per kW/h” is according to your local electricity rate.
Determining the system efficiency
Due to the high frequency nature of the output of the LMPS power supplies, the input power factor must be used to determine
the system efficiency. Take the input watts of each power supply and use the appropriate power factor curve on figure 9
(p.18) to determine the system efficiency.
Additional Considerations
Distribute the load equally between multiple power supplies. This ensures a uniform level of light across the power
supplies.
Contact HEICO lightingTM for more details about power consumption calculations when using a distance factor.
All calculations are theoretical. Measurements made on the real life installations can differ from the calculations.
EXAMPLE
Modules : 95 PolyoptikTM 20˚X20˚ 3000K & 20 PolyoptikTM 180˚X180˚ 3500K
Power supply : LMPS-750 (75W)
Twisted pair extension : 50 ft
Distance factor at 50 ft: 0.77
Wattage 1 =
95 PolyoptikTM 20˚X20˚ 3000K X 1.35 watts
= 128.25 watts
Wattage 2 =
20 PolyoptikTM 180˚X180˚ 3500K X 1.35 watts
= 27 watts
Total wattage =
128.25 watts + 27 watts
= 155.25 watts
Watts available for LEDs = 75 watts X 0.77 = 57.75 watts/power supply
Number of power supplies required = 155.25 watts total/57.75 watts/power supply = 3 LMPS-750
Therefore, to distribute the load equally, install 38 modules on each of the first 2 power supplies and install
39 modules on the third power supply for the total 115 modules.
Total system power consumption = 63 watts + 63 watts + 65 watts = 191 watts

TWISTED PAIR WITH SINGLE WIRE LOOP
Calculating the wattage of the LEDs to be installed
The following method can also be used to calculate the load on only one power supply or individual sections of the
architectural lighting project. Please note that the “watts per module" value must be taken from the specification sheet of
the appropriate product.
wattage = number of modules X watts per module
total wattage = wattage of module type 1 + wattage of module type 2 + (…)
Applying the distance factor if applicable
If the power supply is installed away from the LEDs, use table 6 below to apply the appropriate distance factor to the
wattage of the power supply.

The distance refers to the distance between the power supply and the first LED module.
Watts available for LEDs = wattage of the power supply X distance factor
The values given in table 6 are usually enough to do proper distance factor calculations. If the distance between the
power supply and the first LED module falls between two columns in table 6, it is possible to calculate the distance factor
using linear interpolation.
Target distance factor =
(target distance –length 1) (distance factor 2 –distance factor 1)
+ distance factor 1
(length 2 –length 1)
Example (target distance of 88 feet with LMPS-750)
Target Distance factor =
(30 –25) (0.50 –0.69)
+ 0.69 = 0.65
(50 –25)

Distance factor at 50 ft: 0.65
Wattage 1 =
