Lento pioneered pure sine wave technology in its inverters, UPS and power supplies. Our Sine wave inverters output stable frequency and voltage, mimicking mains power supply, making it perfectly suitable to power expensive equipments, especially inductive loads that do not work well on square waves. Sine wave technology also does away with annoying RF interference due to absence of harmonics and ensures longevity of expensive equipments.

Unlike other technologies that rely on quasi Sine wave, Lento technology is pure Sine wave and output from inverters conforms to mains power supply in terms of frequency and voltage. If you plan to power air conditioners, computers, refrigerators, microwaves or any electronic equipments, your best bet is to go with Sine wave technology to ensure reliable operation. Even for fluorescent tubes and fans, Sine wave works better because all these equipments, whether electronic or electrical, are primarily designed to run on Sine wave power. Our sophisticated digital state of art circuitry guarantees Sine wave frequency and voltage output within closely specified parameters.

Square Wave: Very old style Inverter. OK for Bulb Loads. Not good for other appliances like Tube Lights, Fans, coolers and motors etc.

Quasi Sine Wave: In basic it is square wave inverter, but at low load conditions the circuit in this type of inverters cuts some part of the square wave. Good for Bulbs. Not good for other appliances like Tube Lights, LED lights, Fans, coolers and motors etc

Trapezoidal Wave : There is no inverter in the mass market which is able to supply the trapezoidal waveform. This type of waveform is still better than Square wave and Quasi Sine Wave. Some brands claim of it’s Inverter a Trapezoidal Wave Inverter which is a false claim.

Microcontroller Based or Digital Inverter : This in basic is a Square wave Inverter only. The difference is that the control in this type of inverters is done by microcontroller. Increased reliability of inverter but still not safe for appliances.

Microcontroller Based Pure Sine Wave: inverters are not pure sine wave as they claim it is. It gives low battery backup and it is very costly. Also these inverters create a very irritating high frequency noise which is very much disturbing.

DSP Based Sure Sine Wave : This is the world’s latest technology Inverter manufactured by Lento. This inverter is having all the advantages of Sine wave Inverter with backup time equal to square wave inverters. It creates no sound in load and in inverter. This gives exact replica of A C main which is best suited for all kind of electrical appliances as all appliances are design to operate on this. This increases the appliances life span in terms of operation life.

LED is the light of the future and Lento has developed advanced LED lighting devices in the form of LED bulbs and LED tubelights with high lumen output, excellent reliability, durability, color rendering and affordable prices. For interior lighting we have affordable energy efficient LED lights and for streetlights we offer next generation high lumen high watt LED arrays in the range of 3W to 150W which includes LED Bulbs,Tubelights & Street Lights. Our LED lighting solutions will save the nation a huge amount of energy and reduce green house gas emissions as well as the carbon footprint. 

Today you can buy a variety of LED lighting for home and commercial illumination with warm, cool and natural daylight color output. In addition you can also buy sophisticated RGB LED systems with controllers that allow you to vary the output in terms of light color and level of illumination. For most homes the standard is to go in for fixed output LED lighting fixtures. A step up is a controller that allows you to dim or brighten the LED from zero to maximum power. Regardless, LEDs, when matched with appropriate controllers, can last for 50000 to 100000 hours and emit less heat while allowing for flexibility of design. Lento offers the standard range of LED luminaries and plans to introduce RGB variable lighting in the near future to create the perfect mood for interiors.
