Hi Guys
Ok, so I am sure this has been debated to death by now, but I have a couple of questions/observations.
This came after seeing the thread about the Black Box by @leslie hempel.
So, help me understand. Lets take the black box as an example.
It is a 165W light, that provides a spread of 60cm. So if I am correct, that unit pulls 165W per hour. Now, to do a 1.2 metre tank with those lights, you would need 2 of them, which would amount to 330W.
If you were to use 1.2m long T5 tubes, it would be 54W per tube, and I believe 4 of them would be more than enough, so you are looking at 216W.
Breakdown, LEDS do a spread of 3.6CM per Watt.
T5 do a spread of 5.5CM per Watt.
Now, the question. If I take my home, which mainly runs on LEDS, I get much more light, and bigger spread, for much less wattage, vs old school technology. So, please educate me, why are LEDS for marine tanks still so power hungry? Shouldn't the technology allow for better power consumption?
Zetlight ZS-7300 200W, 90 * 60 CM, so thats a bit closer, but still more than a T5, at 4.5W per CM.
Zetlight ZT6800, 230W, 101.6 CM, so still more, at 4.4W.
Ok, I am only going on length here, did not take width into consideration, or depth, as I do not easily find info on T5 Spread.
DISCLAIMER: I do not know much about LEDS, and I only have LPS and Softies, I am not trying to diss LEDS at all, I am really just curious.
