President Chain Store Corp, the operator of Taiwan’s largest convenience store chain, 7-Eleven, has planned to cooperate with Delta Electronics Inc to sell LED light bulbs to meet the increasing demand for energy-efficient lighting products.

Previously, President Chain has partnered with Everlight to sell 8-watt LED bulbs under the Everlight brand, however, this time it would market co-branded 8-watt LED bulbs with Delta Electronics Inc.

According to President Chain public relations official Irene Chuang, the new LED light bulbs would hit the store shelf soon. But she declined to say the number of the co-branded light bulbs the company expects to sell, at NT$399 each, by the end of 2012. The retailer sold out of 100,000 Everlight LED bulbs at NT$299 each within a month between May and last month.

For Delta, the company’s solid-state lighting division director Roland Chiang said in a statement that it hopes the cooperation with President Chain will further popularize LED light bulbs, boosting the company’s market share.

Like Everlight, Delta uses a pricing strategy to woo customers, as every purchase of two bulbs would cost NT$599 rather than NT$798. In May, Everlight cut its 8-watt bulb to NT$299 each from its previous price of NT$799.
