    Hey guys,

    I upgraded to a 96g Tank a while ago, so I'm in the process of upgrading my lights. I currently have 2 T5 tubes. I cannot even remember what the K ratings are. Its 1 blue and 1 white, both with reflectors.

    I dont want MH because of the distance they have to be from the water and the heat they transmit.. and the price ofcourse.

    Neway, I thought I'm gona make my new hood to support 6 T5-lamps with reflectors. Starting out with 4. How successful will this be ? What kinds of corals will I not be able to keep happy ? :D What lamps do u guys recommend I should put in (K, manufacture, ?). I looked at the T5's they got over at www.dorrypets.co.za, does anyone know what manufacture they are ?

    Atm I have an open brain, mushroom polys, finger coral... all of them seems to be really happy with only 2 T5 lamps, so I guess the new light setup will me a good improvement ?

    Thanks !! - happy to see that the new web host is up a running

    Sounds good, if you look for 10,000k or 14000k rated lamps you can keep most corals - even sps.

    How deep is the tank?

    g = US g or UK g :whistling:

    I prob will be shot down for saying this, but T5 do get hot but it is spread out over wider area, so to me it is a myth that MH get hotter than T5's.

    If it was me go for min 4 10k & 2 Blue. If you can get diff makes of well known T5's for 10K maybe even get 1 or 2 Fugi purple.

    80W T5, kick ass, I have two of them with 6 other t5's and they are great. Great for sps and clams. I going be adding at least one more. I would suggest 1 white and 1 blue.

    Dory's globes are no name brands, but in saying that, they are decent, I have one of Dory's running next to my Geisseman, and I can't see I difference, but it maybe the differences are lifespan or intensity (which our eyes cannot detect.)

    would also like to know the diff?except price off course.if it's only lifespan then I'll live with that because you could buy like 2-3 for the price of branded bulbs

    Prob also has to do with the spectrum of light they produce. The cheap 10k T5 I got went yellow very quickly. Remember their is more to the lights than we can see.;)

    Yeah, I will be looking out for that, I have two new 80w, one form Dory and one Giesemann. It will be interesting to see how they fair.

    But one thing is, I would prefer replacing globes every 6 months, so might not be able to see the difference.

    Lets see 6 x 80 Watts equals 480 Watts of power.
    3 x 150 Watt metal halides equals 450 Watts of power.

    Metal halides are pretty expensive to set up originally. But generally they last longer than T5 lamps. T5's need to be replaced every 6 months to 1 year. Metal halides can last 50 to 80% longer.
    Replace 6 T5's at around R200. Over a year costs R1200-00 to R2400, depending on how often you replace and cost of the lamps. Replace 3 x 150MH costs around R1350 per year if replaced once a year.
    So over a few years it become much cheaper to run MH.

    I prefer to run a combination. MH as main lighting and 1 or two T5's for colour correction. So something along the lines of 3 x 150W MH for a 1.5m tank would be ample for main lighting, either 10 000K or 14 000K. Then either of the following to obtain a nice light appealing to the eyes. 2 x 39W blues or 2 x 54W blues. Because these T5 lamps are not main lighting they do not need to get replaced as often. Replacement only necessary when the lighting is no longer visually appealing.

    You will find that opinions will differ a lot on all things marine related. But lighting is often over rated. Concentrate on flow and feeding first. If you get those two parameters correct lighting is less of an issue.

    Agree with Hill, you will hear guys running multiple 400w MH's, not always necessary. Studies show that most of our tanks have too much light and loads that is not used up.

    There are pro's and con's to both. My choice of T5's is because I can have a closed hood and relatively small temperature increases.

    The one advantage that T5 have is dispersion of light.

    Well some of us see that as a negative. I prefer the natural looking shimmer lines created from point source lighting.

    6 T5s will be awsome!go for a brand like ATI or Geisiman,excellent quality.
    if it was me,i would go for 4 whites,1fiji purple and 1 blue.
    SPS will thrive under a decent brand of T5s

    They are basically "whiter" than blue in the 18000K range, and gives a different colour to your reef.
