LED lamps are now rapidly replacing conventional incandescent lamps and compact fluorescent lamps (CFLs) in domestic and commercial lighting. Understanding the data that is presented with respect to lamp performance and operating life is the key to making informed product choices.
Data on LED lamps is to be found on their packaging, or in data sheets. Some of the information is based on verifiable facts but some marketing claims may not be based on sound engineering principles. A number of major global brands are now competing for a share of the general LED lighting market. Prices are falling as the technology matures, manufacturing process become more refined and the economics of high volume manufacturing and supply chain management come into play. For a given product, prices from these reputable suppliers will be found to be within a range of perhaps ±20%. Products from lesser-known brands, or even those of unbranded LED lamps, may at first appear to be significantly lower. However, to be able to sell at these lower prices, compromises will have been made in the quality of materials and components employed – it is unlikely that significant cost advantages in manufacturing can be realized. The quality of components in the electronic circuits inside LED lamps is critical in determining product life, so you can expect early failures in cheap lamps and a poor return on capital outlay. The reputation of the whole LED lamp industry is dependent upon consumers understanding this argument.
