Good quality luminaires like PHILIPS, one do not have to change every 2-3 years.
I have been using a higher grade than PHILIPS Consumer series that is rated at 25,000Hrs and this is the 6th year in service. Based on my average 4-5hrs use per day, this downlight will last me another few more years before needing to change.

what kind of lights are those?

These are semi-professional PHILIPS Lighting under SMARTBright Series. I still have spare, thought needed to replace them frequently but been sitting in my store room since bought brand new.

Lumens not higher, just the same but power is lower.
I recently compared and this is what I found out:

PHILIPS Consumer Series
17W 1200lm 15,000Hours 1-Year Warranty
Plastic Bezel

PHILIPS Semi Pro Series
12W 1300lm 30,000Hours 3-Year Warranty
Metal Bezel

Both are recessed type and cutout hole is 6".
