Electricians - Lighting question (recessed flood)

So my Dad is totally not a handy man. He has recessed flood lights all over his house and they keep burning out.

Like, once a month burning out. It's REALLY annoying.

I can't seem to figure out the problem. He said some guy told him that having the light on when you replace it is what's doing it, and it might have been, since my dad is an idiot and replaces them with the switch to "on" so he can "tell when it's in". I have since taken over these replacement duties as I like my dad and don't want him to die while installing a light bulb because he's an idiot.

I also noticed, one recent bulb I took out said 85w and the one I put in said 65w. I figure that could be the culprit as my dad who is probably unknowingly sabotaging his own lighting by buying lower-wattage bulbs and putting them in higher-rated sockets could be burning them out quickly.

Anyhow, is there any advice the internet could provide?

Again, these are recessed flood fixtures, I can provide more info if needed.

    A temperature issue due to low airflow/trapped heat leading to quicker bulb burnouts, perhaps

    I think There is a type of bulb (halogens maybe?) that you aren't supposed to touch with your bare hands as it shortens the lifespan. What type of bulbs are they?

    Halogens. Your body oils get on the bulb and cause them to overheat, basically. See if the 65w bulbs help. Most recessed fixtures aren't rated for higher than that and the excess heat can shorten bulb life.

    Are you absolutely sure the bulbs are burnt out? Most recessed fixtures have a thermal cutout that shuts the light down if the can gets too hot. I would expect it to happen more frequently than once a month if this were the case but it is something to keep in mind.

    If it isn't a heat issue (too much wattage) or the hot-swapping issue, it is almost certainly a power issue. Could be a loose wire somewhere. Do the lights ever flicker (not just dim)?
