If this strip light has a 40-watt ballast it should not be used with
25-watt lamps, as they will have a very short life. If it has a
25-watt ballast, especially an L-C ballast that produces very poor
lamp current crest factor, I recommend you get one with a decent
40-watt ballast.




Every single tube strip light I've seen has a ballast rated for 36-48" tubes
which runs either one at about 25W. They're ok for 36" tubes but worthless
for 48".
