In Emergency Lights most of the products available in the market from competitors use non-category straw-head LED of 0.06 watts having very low efficacy and life. Havells products use SMD LED 0.2w (LM 80 tested). Almost all competitor products use lead-acid batteries which are Highly toxic, heavy, unreliable, prone to acid leak and go into deep discharge if not charged for 3 months after manufacturing. Havells products use state of the art Lithium-ion batteries which are solid state batteries having lesser weight, longer life and better performance. Most of the products available in the market use cheap capacitor based chargers which require 10-18 hours of recharging time and do not work in rural areas where voltage drops below 100 volts. Havells products use robust chargers which come with micro-controller and SMPS technology thereby ensuring constant voltage and current to recharge the product in 3 to 4 hours even when the voltage drops to 70 volts.
