@Brity, you are right again my friend, those LED bulbs are expensive, but from time to time, I did see some promotions via carrefour and lulu on these bulbs and stocked them for our home use. They were decently priced, but they do seem to have a shorter life compared with Philips and Osram brands. Hope the govn't here provide us with some subsidies to reduce the cost of these bulbs and encourage its usage for everyone!
