Consumption

Comparison of consumption between technologies, using economical lamps and LED lamps

Conventional Lighting - Residential

Example of a residence with 12 economical lamps of
25W / 127V

25w X 12 Bulbs
X 8h X 30 days

1000 X BRL 0,527 = 23,71

Monthly consumption = BRL 23,71

Annual consumption = BRL 284,58

Example of a residence with 12 10W RedunLed lamps.
1 10W RedunLed lamp = 1 economical 25W lamp.

10w X 12 Bulbs
X 8h X 30 days

1000 X BRL 0,527 = 15,17

Monthly consumption = BRL 15,17

Annual consumption = BRL 182,13


KWh cost = BRL 0.527 (Source enel 2019)

Comparative illustrating the equivalence between technologies (Lamps).
Our REDUNLED technology makes it possible to illuminate more environments with less consumption and convenience.



Hybrid Lighting System



In this illustration we point out the possibility of photovoltaic integration with load management already integrated in our technology.

Its cost with lighting energy and other ultra-low voltage equipment can be reduced to 0% of the electricity distributor's utilization.

Clean and sustainable energy.

Public Lighting


REDUNLED technology also applies to public lighting.

Our system consumes less electricity than conventional metallic and Led systems.

The technology functionality, in addition to reducing consumption, makes it possible not to interrupt the light source (lamps) with an intelligent redundancy system, longer lamp life and reduced risk to zero in terms of electric shock.

In some cases, we can reduce energy consumption to 0%.The hybrid system is capable of managing the demand for energy consumed.

Conventional System

Example of conventional street lighting/ Calculation of monthly consumption.


250w X 25 Bulbs
X 12h X 30 days

1000 X BRL 0,14 = 315,00

VOLTAGE AC 220V
NOMINAL CURRENT 28,40A
INSTALLED POWER 6.250W
ET.IP 10Kva
MONTHLY COST BRL 315,00
ANNUAL COST BRL 3.780,00

Example of REDUNLED public lighting/Calculation of monthly consumption.


60w X 25 Lamps
X 12h X 30 days

1000 X BRL 0,14 = 75,60

PRIMARY VOLTAGE AC 220V
SECONDARY VOLTAGE DC 60V
SECONDARY CURRENT DC 25 A
INSTALLED POWER 1.500W
ET.IP 4Kva
MONTHLY COST BRL 75,60
ANNUAL COST BRL 907,20

1 REDUNLED Bulb 60w = 1 Bulb / 250w Sodium Vapor

Primary load reduction installs on the 13.8Kv circuit

Cost without financial charges


In this comparison between the applications of technologies (metallic steam x REDUNLED) see the reduction in monthly consumption.
Annual savings of BRL 2,872.80 per circuit of 25 lamps.

Positive points of the REDUNLED system

Reduction of electricity consumption - reduction of the load on hydroelectric plants;

Increase in water resources consumed for electricity generation;

Increase in water resources consumed for electricity generation;

50% decrease in the emission of CO² in the atmosphere due to public lighting over 20 years;

No emission of ultraviolet light, attracting insects to the surroundings of the light source;

It does not emit infrared light, it does not heat the environment, providing a decrease in the thermal load and consequently a decline in the electrical energy consumption of air conditioning machines;

Lamp life of approximately 50 thousand hours, with conventional lamps, e.g. metallic vapor 8 thousand hours of life;

Instant electrical redundancy of the light source in question (lighting in general);

Zero risk of accidents of an electrical nature, such as electrocution;

In the event of a fire, the fire department can safely operate with all lighting active, the redunled system operates with ultra-low voltage;

The REDUNLED system meets NBR 5410/2009.
