ABSTRACT:
A striation correction circuit300is arranged to apply a first striation correction current to the first fluorescent lamp L1and a second striation correction current to the second fluorescent lamp L2. A first voltage appearing across the first fluorescent tube L1due to the first striation correction current is substantially similar in magnitude but has inverted polarity with respect to a second voltage across the second fluorescent tube L2due to the second striation correction current. Detection of an end-of-life condition of a fluorescent lamp is facilitated.
