All the sites i checked show only indoor table lamps and cars and their parts

The key with getting something good on those sites is a combination of using the correct keywords and checking frequently. "Fluorescent light" is usually the term I use. As for frequency checking daily is a good place to start. Once you do the initial search it only takes a few minutes each day to check for new stuff.

Also on some of those sites you can exclude car stuff using the categories.
