    thank you - some people are doing their homework - I am glad to see it. Little Jack is doing well. as far as "holy grail of lighting" - it is close but two or three tricks are missing in order for me to be the holy grail of lighting. 1) lighting and thunder effect - I was promised that it...

    what would I do if I were you? I would ask myself - am I going to upgrade anytime within next 3-4-5 years to a bigger tank? if yes, what tank size you have in mind? 90g? 120g? 180g? if less than 120g (48" long) than two IO will do the job. if you think about 72" than I would go with 160W...

    two IO units will be more than enough for your tank and at first you would need to go slowly and start at 50% - trust me, otherwise you will burn your corals. IO units as well as any other PS unit have internal cooling system and fans. as long as you have a space between the top of canopy and...

    all I want to make sure we compare apples to apples and not apples to oranges. AI unit consists of 24 3W CREE LED bulbs at the price of $629 that translates into $26.20 per bulb. I assume we can agree on it. Lets take Black Python 160W that consists of 54 3W CREE LED bulbs at the price of...

    A) If you believe AI is cheaper - please show the math based on Wattage or per bulb cost for someone who has 48" or 72" tank. b) also - review functionality of AI controller (you need to buy one on top the light fixture) with the software of PS. in order to get full AI functionality you need...

    talk to CY about any other discounts and payment dates. I know that those who pay early and want their units earlier - it will be possible to have units in 2 weeks.

    this the unit I was reffering to: http://pacificsunusa.com/?page_id=507 let me check if 140 is the typo and should be 160 or if the 60" Deimos have 3 led panels simply a little bit smaller.

    Height of your tank 30" - I would suggest 3W. Options: 1) 3 IO units - each unit must be programmed individually. If you have mix reef tank - you will be fine with 3 IO. Pros - you can have different light temp on each side of the tank - for example 16k on left, 18k in the middle, 21k on...

    if you are confused - PM me or call me. LEDs are not confusing if you can figure out what you want and formulate questions that should be asked: a) is the unit running any cooling system to protect LED bulbs and their longevity? if yes, is it 24hrs non stop or controllable based on needs? b)...

    there is no pink LED bulbs out there so you cant get that specific color out with LEDs. thats why they came out with T5 supplementation and possible usage of KZ Fiji Purple etc. you wouldnt add Blue + T5 since you can increase Kelvin temp with LEDs and achieve any color from 13k to 23k via LEDS.

    let's say we are talking about Phobos 48" - it has 2 54W T5s. Depending on the brand of the bulb you use you can go from 6 to 12 months. I mean the idea behind mixing LED & T5 was to supplement pink color that is not achievable with LED at the present time. so you would add KZ Fiji Purple or...

    not actinic suplementation fixtures. it is All in One type of deal.

    for 48" tank - you would need to go with 2 Black Paythons (master and slave) or Phobos 48" (LED & T5 combo).

    Yes, Chris is correct. i think the name of the program is 'Virtual Windows' that allows you to run windows apps.

    ok, so lets go by the numbers from the PAR data info: so lets look from back to front - lets assume you want to have PAR around 100-120 to extreme ends (back and front of your tank) and higher PAR towards the middle of the lamp. 100-120 coverage are is about 75cm by 120cm so lets put it in...

    I would move some SPS towards middle from sides and you should be fine. once corals grow out - you will need to add 3rd module.

    this particular design has been in place for about 16-18 months. they started with led tubs (T5 and T8) and moved to modular units and than LED & T5 combos. flaws? - from Nov 09 to Mar 10 - 2 blown external drivers and to make it more fun - same guy. both replaced in 24hrs in US. Nov 09...

    72" tank - master and slave unit only - tough call - and it depends on your aquascaping. if per say you have 2 islands where corals are located - than yes. if you have corals in the center of the tank and sides are empty - than yes. I mean - it really depends on your aquascaping. there is a...

    I would not use any focal lenses on 24" tank with CREE units. there is no need for it. at 29" depth - you have over 200 PAR. I would go with focal lenses in two cases: 1) thin tank 18" and you worry about light spillage and space above the tank to raise light fixture. 2) you have a deep...

    Cy will make an announcement about it shortly. He is working hard to get best possible prices.
