Understand from a friend who worked in Strongly Lighting before that the company supply Osram lighting for some HDB projects.
He no more working there so can't check with him on the pricing.
Can try to call them to find out the price...
WOW, so much Qs on glass have answered here. Still have a couple of Qs.
1) What is the diff. between tempered glass and laminated glass?
2) Is there such a thing called laminated tempered glass?

Used it on my HDB main door, which directly under west sun all year round for five years and the door still look new.
