[APD] ODNOS
Okay, I've got four overdriven 40W lamps on a 55-gallon, and finally got
around to setting it all up. I hate to say this, but it looks like a lot of
trouble for not much. :) The lamps get warmer, definitely: but I don't see
a lot of difference between 4x40 OD and 4x40 standard. I shut it down to
one bulb, and compared to a standard one I have -- cast it at the ceiling
from the floor, and both looked about the same. I even tried the
ink-through paper test (take several sheets of thick, white paper, and write
something on the bottom one. Hold it over a lamp, and lift it until you can
no longer see what is written on the bottom sheet. Measure the distance.)
The difference between teh ODNO and the standard was marginal, and may very
well have been more due to the fact that the standard bulb was older and had
some water marking on it.
Have I stumbled onto some sort of smart ballasts that know how many bulbs
are on them, and aren't cooperating? :) These bulbs should be twice as
bright as a standard flourescent, right? So far, all I've managed to do is
find a way to use a flourescent as a heater -- they get much warmer. Did I
wire something wrong, or am I just not able to perceive the difference in
light output?
