Seems like a fair price to me since this is a specialized low volume
product with line cord and built-in switch. I can't tell if the lamp
is replaceable, but if not it is similar to the GE BriteStix - which
is available only in 2-foot, 20-watt version.
You could, of course, buy a standard 4-foot, one-lamp strip light
fixture, paint the fixture black, add a switch and line cord and then
a black light fluorescent lamp. When you get all done you will have
spent more than $40.

If it's having trouble starting you may just have a bad ground to the
fixture.
Those strips are easy to find, though they have those horrid low power
factor ballasts that run even the 4' 40W tubes at no more than about 25W.
You can get *far* better performance by fitting one with an electronic
ballast and F32T8 tube.

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".

You need to look for commercial grade fixtures, such as the
Lithonia S 1 40 120 ES strip light. This is designed for a 4-foot,
34-watt T12 lamp. Grainger lists this fixture for $25.30.
http://www.grainger.com/Grainger/productdetail.jsp?xi=xi&ItemId=1613506256&ccitem=
You will notice that the ballast losses are rather high for the
one-lamp EM ballast used in this fixture. I would recommend a fixture
using a 4-foot 32-watt, T8 lamp and matching electronic ballast.
The Lithonia part number would be S 1 32 120 GEB. I don't see this
listed on the Grainger Web site.
