Default Lighting ... or Correct Me if I am Wrong
(seeOtwo) wrote in message . com...
Here, let me confuse things a little in an effort to make my point
clear:

AHSupply and other vendors sell reflectors that claim to increase the
light that hits the water by up to 196%.

Also T5 type bulbs are advertised as up to 400% brighter than regular
fluorescents.

Now, if you get a 55 watt bulb with a Miro reflector does that mean
that you actually have 55 + (55 * 196%) = 55 + 107 = 163 watts?

And is a skinny T5 tube that is 54 watt actually 54 + (54 * 400%) = 54
+ 220 = 274 watts?

Also - a 10,000 Kelvin Coralife VHO appears totally white to the eye
while a 10,000 Kelvin URI VHO appears violet-pink.

Well, I suppose at this point most folk are confused.

The point that I try to make is "use what works for you".
Calculations are exactly that - just calculations and nothing else.

Good points
I see all sorts of figures and such but you have to question some of
the supposed benefits of certain light/Kelvin temps etc.

I think in answer the the question, the PC lighting is about 2x as
bright as the 80w set up. Bulbs last longer, you'll get more watt per
$ of electric.
