I have 2 floor models and one table top. The table top has a caddy attached for stitch rippers, small scissors, etc. The floor lamps sit on carpet and are very well balanced. I have had one for MANY (15+) years and love it---never had to replace bulbs yet. I do know that Home Depot carries them also and they are not so expensive.
Other stitchers use Halogen bulbs---which are bright but get very HOT----too hot for me to work with it on in the muggy summertime.
