Luminous. The name itself is enough. I have Luminous Cruze installed at my home. It is a pure sine wave UPS system which can easily handle various household electronic machine on power-cut. It is a 2 KVA inverter for refrigerator, fans, washing machine, Lights etc. while on power-cut. It is easy to use. It gives automatic power supply and can easily last for about 10 to 12 hours with 24v double batteries. It is a money for value product and definitely good for home usage.
