OK...
Maybe they were like the ones I found in my most recent 2 apartments.
I save them to put back in when I move out.
Namely, 130V 60W, often 3500-hour, with nominal light output sometimes
stated as around 600 lumens. My experience is that these at 120V only
barely squeak past the light output of 1,000-hour-rated 40W incandescents.
And, I use some 9W CFLs that get close-enough in light output to those,
along with some 13W CFLs that are noticeably greater in light output -
and lasting on-average in my experience 4,000-plus to 5,000 hours,
improving as the years go by, so-far...
130V 60W incandescent at 120V consumes 54 watts...
I save at least 41 watts by replacing each with CFL, and at USA-average
residential electricity price of $.11-plus per KWH this means $18-plus
electricity savings in 4,000 hours from purchase of a $5-or-less bulb.
At that rate, I don't care if incandescents are free or lifetime-
guaranteed or even both - incandescents cost me more for "general
lighting" at USA national average electricity cost, let alone mine in
the Philadelphia/NYC/Chicago metropolitan areas class.
