When we moved in, there were a ton of burned out bulbs, so I bought about 20-30 of them and replaced burned out bulbs all over.
Damn, if I were a tenant, I totally would have made my landlord pay for all those bulbs. It's one thing if they burned out over significant time of your usage, but if they were already out when you moved in, or burned out really soon thereafter, I would have called the landlord and said, "Hey, I'm gonna have to buy all these bulbs since they're out. Do you want to buy them and install them? Or would you rather I buy them, send you the receipt, and deduct the cost from my next rent payment?" Said nicely with a smile :-)
I did consider it. However, decided against it for several reasons.
1. There was a list of items I needed done, and I had to fight with a flaky, ditzy real estate agent to get them done. These were things like boarding up a hole in the wall in the basement, getting the ceiling fan/light in the bedroom to work, rehanging a door, etc. I was out of energy & patience dealing with those things.
2. Landlord is out of state, and we wanted to establish a good relationship. I've lived here 3 years and still haven't met her, or even spoken to her on the phone. We have email and mailing address.
3. When I finally found the damn things, they had a sale on lightbulbs. Very random, but great, and I had a coupon. So after the sale + coupon, that helped a lot with the cost. I think it was close to 40-50% off. Additionally, I split the cost w/ my roommate.
4. My roommate was, and is, very much not in the real world of what landlords need to do and what it's reasonable to ask. At the time, she was in the middle of a particularly out of touch phase, and I'd had to squash a number of things. (No, it is not reasonable to ask your landlord to put in a larger hot water tank when the current one is perfectly fine, not that old, etc.) Paying for the lightbulbs was a much lower cost for me than dealing with opening that can of worms again.
Overall, it wasn't worth it.
