hi all, would like to ask about recessed eyeball lighting.
i noticed there is the type which are similar to downlights whereby if it gets spoiled, will have to change the entire thing pull out the clip from ceiling, connect wiring, etc.
then there is the 'modular' type where the housing is permanently fixed and only need to change the bulb inside.

so my question is as followed:

1. What do you call the 'modular' type and the 'all in one' type?
2. Is it true that the 'modular' type spoils faster, like 1-2 years, but the all-in-one lasts longer up to 5 years?
3. is it easy to change the bulbs in the modular type or is it restricted to the exact same manufacturer of the housing?
4. any recomendations for brand or model of anti-glare type of recessed eyeball light for living / dining area?

thank you so much for info and advise

p/s: tried to google but dont know the correct terms to search and not getting the right info
