Replace *Working* CFs???
I have just heard two different opinions on a subject that would seem to have little grey area. The question is - do Compact Flourescents lose their juice over time, with that time period being 18-24 months?
I have had two different aquatic gardners tell me that CFs not only lose their lumen output rating over time, but that their spectrum shifts over time favoring algea over higher order plants.
As a proof point - the gardner showed me how my Cabomba has grown "stringy" with long sections of stalk between foliage (as opposed to nicely/closely bunched foliage). His point was that the plant (receiving less energy) has gone into light seeking mode, and is trying to grow up to where it thinks the brighter light is (i.e. closer to the surface).
On the other hand, I have heard this is just bogus.
Can I get the brain trust chewing on this one?
Thanks in advnace!!!
