Hello every one,
HELP PLEASE!!
After reading all this thread and all the different stories, results and opinions, I would like to ask you if you could please correct me if I am wrong and also give me your opinion on the choices I am looking at. I thank you in advance for your help!
1. Watt per Watt do T5s produce as much PAR as Metal Halides (asuming same K bulb rating to make it easier, like say an XM10k and the equivalent in a T5 bulb like Aquablue plus)?
For what I have understood, T5s produce more PAR watt per watt then what metal halides do.
2. An XM10k bulb can do fine for 18months on an IC ballast. Can T5 bulbs also last that long? (I do understand that color and PAR output will decrease with usage).
For what I have understood, T5s can only be used for 12 months if that, and then they need to be replaced.
The reason I ask is because I am trying to decide between to set ups.
Set up A: 2x250w XM 10k SE bulbs in Luminarc3 reflectos ran by 2 250w IceCap ballasts. Total Price for unit $650 (bulbs included)
Set up B: 6x80W Aquablue plus SLS-Tek retro ran by 2 IceCap 660 ballasts. Total price for unit $650 (bulbs included)
3. In setup B, will the two 660 ballasts be overdriving those bulbs for a total of 880 watts of power? I see that the 660 IceCap ballast can produce or should I say can suck up as much as 440 watts each for a total of 880 watts. I hope this is making sense.
I am asking this because out of setup A (the metal halide set up) I can expect to pay MR/MRS Electric company 500 watts when the set up is on, but how about this T5 set up. Can I expect to pay MR/MRS Electric company 480 watts for the 6-80watt bulbs or will the 2-660 ballast automatically overdrive/sucking-up a total of 880 watts when the set up is on?
This will be for a 90% sps, 5% zoanthids, 5% LPS tank.
Dimensions will be 60"Lx24"Wx24"T or 60"Lx18"Wx24"T
I plan to have this set up for at least 3 years because after spending this money I may not be able to even buy socks. LOL
In a 3yr period I can expect to replace the 2MH bulbs twice for a total of $780 (setup plus 2 extra/replacement bulbs at MD). But how often should I change the bulbs on the T5s, so I can have my bottom line for the 3yr period (setup plus extra/replacement bulbs from RG)?
I really value your opinion and greatly appreciate your time and help, so I can get this thing done right from the beginning.
Thank you!!
