These bulbs are available in two sizes.  The tiny (2mm x 6.5mm) grain of rice bulbs with long (20" or 500mm) wires are perfect for adding lights to kitchens - plinths (kickboards), countertop lighting (add a small "pelmet" of wood, a dab of glue to hold the wire, connect to your 12v system, and you have concealed countertop lighting!) or bathrooms.  The larger grain of wheat bulbs, with the same long tails, give out a slightly stronger light (they are 50ma instead of 30ma) are great for making your own lamps, or where size is not an issue.  (Though even these bulbs are relatively smal)l.

Use the small ones to light up your opening oven - make a tiny hole in the back, and add one of these bulbs.  So many uses - let your imagination go wild!
