Energy efficient tube light
I came across this important matter of interest in an advertisement in the quarterly issue (Oct.-Dec. 2014) of Business Magazine from the Bangladesh German Chamber of Commerce & Industry. The advertiser claimed that their brand of imported tube light (Brand-SLED) consumed far less specific power and much better illumination, consuming far lesser electricity than the local brands sold in the market. According to them it was ideal for use in big factories (like garment factories) and other industries, and that it could save around taka twelve lakh annually if they use around one thousand such tube lights in their establishment. However the price of their tube is four times higher than the local brands.
In my view, to authenticate their claim they should ask BUET to carry out a comparative study and actual test on the matter related to their claims. If the supplier’s claim is found true, then the government can be requested to reduce the import duty of these tube lights for overall national interest as it can save scarce electricity generated by imported fuel and local natural gas.
