            Dry Cell Batteries: Dry cell batteries are one of the most commonly used items. These are
      the oldest type of batteries which are still being used. Performance of dry cell batteries has
      undergone progressive improvements through technological developments. New types of dry cell
      batteries with longer shelf life and greater dependability and also rechargeable cells have come
      up. Nickel cadmium batteries and other rechargeable batteries are manufactured in the country to
      meet the requirement of defence, telecommunications and electronics. The growing popularity of
      cellular phones, laptops and imported toys could open the market for a new range of batteries
      that are not produced at present.
            Electrical Lamps and Tubes: Wide range of lamps and tubes are being manufactured in the
      country which include general lighting service lamps such as incandescent bulbs, halogen lamps,
      gas discharge lamps such as fluorescent tube light, compact fluorescent lamp, high pressure
      mercury vapour lamps, metal halide lamps, low pressure and high pressure sodium vapour lamps
      and variety of special lamps. The higher energy cost have led to the development of energy
      efficient lamps consuming less power and giving output as close to daylight. Compact
      Fluorescent Lamps (CFL) which consume about 20 per cent of the electricity for the same light
      output and last up to 8 times longer than the GLS are getting more popular. LEDs have a great
      potential to provide highly efficient lighting with little environmental pollution in comparison to
      the incandescent lamps (ICLs) and fluorescent lamps (FTLs, CFLs). Penetration of LEDs in
      India could significantly reduce lighting load as almost 22-25 per cent of electricity is consumed
      for lighting, which is also a major contributing factor of peak demand. Due to higher costs, LEDs
      are not very popular even though its production has started in the country.
            Light Engineering Industry Sector: The light Engineering Industry is a diverse industry with
      the number of distinct sectors. This industry includes mother of all industries like castings and
      forgings to the highly sophisticated microprocessor based process control equipment and
      diagnostic medical instruments. This group also includes industries like bearings, steel pipes and
      tubes, fasteners, etc. The products covered under the engineering industry are largely used as
      input to the capital goods industry. Hence the demand of this sector in general depends on the
      demand of the capital goods industry.
            Roller Bearing Industry: Roller bearings are essential components in the rotating parts of
      virtually all machines such as automobiles, electric motors, diesel engines, industrial machinery
      and machine tools, etc. Bearings are used in diversified fields. Hence, the product range is vast
      and diversified. The indigenous manufacturers are manufacturing bearings of quality and
      precision at par with world renowned manufacturers in the diversified range of general purpose
      where the demand is large to justify indigenous production on economic consideration. Bearings,
      generally used for special applications that require high technology are still being imported.
      There is a considerable scope for development of bearings of smaller size and lighter weight with
      improved performance in harsh operating conditions like high or low temperature.
            Ferrous Castings: Ferrous castings are pivotal to the growth and development of
      engineering industries since these constitute essential intermediates for automobiles, industrial
      machinery, power plants, chemical and fertilizer plants. Indian foundry industry is the third
      largest in the world. This industry is now well established in the country and is spread across a
      wide spectrum consisting of large, medium, small and tiny sector. The salient feature of the
      foundry industry is its geographical clustering. Typically, each foundry cluster is known for
      catering to some specific end use markets. For example, the Coimbatore cluster is famous for
