Most if not all lighting shop sells only consumer grade lighting (Lifespan 10-15Khrs) which is fine for most domestic application. Typically usage around 4hrs/day, it will last 6-8 years. Not all brands the ratings are equal. Stay with reputable and established brands like Philips/Osram. In the market there are those with 30K-70Khrs lifespan for commercial/retail and factory use.
I am using a Philips 50Khrs lighting and is entering its 8th year with no issues at all. Almost the same brightness since day 1.

SIRIM are for domestic use. Most of the professional series lighting are without SIRIM.
Even the RM 8 China branded LED Downlight also have SIRIM.

Most lighting shop recommends their preferred China brand as the profit margins are higher.
