Its Philips T8 LED MASTER line. It is targeted for contractor and whatever lighting professionals it is. price around rm40/4ft tube.
One you see in shop usually Philips Ecofit line. Its not as efficient, low CRI and relatively low lifespan. But its really cheap at rm10/4ft tube.

You don't usually find MAS tube in retail store,but you can directly buy from distributor though.
I usually get my tube from this shop https://www.jllelectrical.com.my/
They don't impose minimum purchase unit, but there will be several days lead time before delivery or self collect.
