[APD] Comparing lighting
Hey folks,
Well - while I'm waiting for my circuit boards (for my LED arrays) to etch,
I wanted to ask your opinions. I've had discussions with gomer about this -
but he's a science like guy - and has odd views of the world :) Time for
some real-world answers!
When comparing light sources, what would you prefer to see as the
comparison?
I'm going to setup a 10g split by a blackout divider to compare the light
from the LEDs to probably power compacts. Using the same water, getting
roughly the same flow CO2 other nutrients etc.
I sit here wondering how to make it a fair comparison... Gomer suggested
comparing current draw at the wall was the proper way to do it (So a 13w pc
might draw 25w total, thus I'd use enough LEDs to match that - maybe 5 5w).
What do you guys think? Should I just compare apples to oranges, 25w of LED
vs 26w of PC (rated vs rated)? What about spectrum - it will be practically
impossible to match them exactly. Do I even try? The LEDs are heavily blue
biased, they make a cool white look warm.
Plants become an issue too, as its hard to get 2 identical plants to
compare, even cuttings will vary...
See part of the problem is I can see 100 ways to make the comparison biased
one way or the other - I'm sure you guys have some ideas...
Ideas/suggestions?
Andy
