If a fluorescent tube (about 5-6 feet long, one of a pair in a fitting) fails to strike or takes many attempts before striking (and then remains on perfectly), is that likely to be a failed tube or a failed starter? Are starters labelled with a code which makes sure you buy a replacement which is compatible? Do you need a different starter depending on the length of tube?
We have several fittings in the garage which are reluctant to start (one or both tubes in the pair) and I want the cheapest solution to provide *some* light, even if an array of LED GU10s or of CFL bayonet bulbs may be better or cheaper to run.
