a cost-effective way to conserve energy of lighting loadswithout heavy investments or cumbersome changes in light ttings.

With increasing energy tariffs, the energy costs even on account of lighting loads is becoming signicant. Numerous methodsof saving lighting energy costs without compromising on lighting needs are being considered. Many a times these includeheavy investments or expensive and cumbersome changes.

LES offers a simpler solution in conserving Energy on all types of lighting including old ttings with copper chokes, new ttingswith electronic chokes, tube-lights, CFLs, etc

QUALITY OF LIGHTING

Ÿ Saves up to 25% energyŸ Works effectively on all types of lightingŸ Improves PF reducing cable lossesŸ Reduces kVA Demand

Ÿ Increases lamp life and reduces replacement costs

Ÿ Reduces THD on current xtures that generate harmonics

Ÿ Ensures consistency of lighting which enables better productivity

Also works on Sodium Vapour Lamps, Mercury Vapour Lamps and Metal Halide Lamps

LES is a device that saves energy by maintaining the power delivered to the lighting loads at an optimum voltage, withoutvisibly comprising on the quality of lighting (Lumen output) or comfort.

All types of lamps (except incandescent bulbs) have a non-linear curve for power consumption and lumen delivered.Depending on the type of lamp, about 20% lower wattage results in 5 to 10% lumen drop, which is not easily perceived by the naked eye.

Appropriate power supply to lighting loads also results in improved power factor and reduced harmonics.

KRYKARD LES comes with a Load Manager to display kW & kWh among other electrical parameters, to know the energy consumption patterns with or without LES, thereby instantaneously quantifying savings in energy.
