    Seems the Plasma frenzy is about to start

    seems pricy, if mobile phone controls adds +$1,000 to the price, I wonder what the price is.

    Price is $1000 but it can be controlled with any other like AC3,Pro,Jr newer RK units, somewhere I read that, been waiting for it to show on the market.
    What I would like to see is a different reflector, like a Lumenarc/Lumenbright; of course some one can mod the light to fit such reflectors but bye bye warranty.
    Another thing is the unit seems to dwarf the 400W MH in every aspect? If most people run 250W, that much light might mean bleached corals or having a three feet high canopy.
    I wonder how high the lights are at Monterey Bay Aquarium off the surface.
    Skip the LED's, I'll wait for a less powerful one of these with a Micro-Lumenarc reflector.
    Hay Tim how's your schedule like this Sunday morning?

    ...Coral Magazine is where I read it can be used with other popular controllers.

    1000 doesn't seem too bad for early adopter tech, esp 1/2 power usage + long bulb life. I'll be home Sunday morning doing a group project if you want to roll by. I may go to the east bay in the afternoon so I could also drop the switches off then.

    Based on what I read the price is decent when compared to running MH. I figured you get roughly 11.5 years of use on each unit with 6hours of use a day. If you are running MH you are replacing bulbs once a year at $65-$90 a bulb. Add on the energy savings and they look good to me. I am just curious to see how you would install them over your tank and how far up they would need to be.

    Lumenarc and lumenbright are not good at all for this unit. They are build for a MUCh larger light source. The next Gen of Seashine have a great reflector. This has all been reported on Reef Builders over the last two years :)

    Since it's control is just 0-10v any controller on the market just about can control it.

    The older MBA units were about 2' off the surface, but why judge it from a tank filled with seaweed that has a MUCH higher tolerance to high light? Not sure about the 40 units MBA has now though. That was just the first two they had. CAS got some units and are testing them on actual corals. I think this is the first real world test with corals they are doing so keep an eye out for Rich's report.

    (they never gave any reports on how that tank is doing)

    Wonder if Rich needed to sign any sort of NDA.

    But yeah, I'm a bit worried about that huge red component when the lamp is at 100%, seem to recall an AA article where they showed (at least in their test corals) that red was not what corals wanted, not so much kill them but that's just that much more wasted light going into the tank.

    Why would he? These are production units now Mike :) Gerald spoke openly about his units at REEFstock.

    I'm wondering if many or a vast majority of the tanks are in the 20" to 24" deep, wouldn't it be way too much light? A plasma unit meant to compete with 175/250W MH I think would take the market by storm; there's no way in any near future I could consider running a 400W halide even that I got some collecting dust. My little tank is 24" deep.
    I mention the LM3/LB reflector just in case manufacturers decide to make a micro version of it to lets say "improve" the plasma, the same way MH went from flat white metal to the fancy LM/LB and what not.
    Like this reflector

    http://reefbuilders.com/2009/06/24/luxims-plasma-arc-lifi-lighting-demoed-monterey-bay-aquarium/

    ...and why is the reflector side of it not shown on the production model? I know they will offer different reflectors using Miro material but the brochure does not depict any of the designs.

    http://reefstock.reefbuilders.com/2010/02/02/new-seashine-lifi-plasma-light-rolling-out-soon-game-changer-gets-initial-pricing/

    A single unit mounted on a light mover at very low RPM would make for nice lighting. Another thing that I wonder is if supplementation with actinics or other blue light sources for more color pop can still be achieved.

    There is a bunch in the works for these lights. The one thing I don't like about the advertising is that they haven't really shown them over a tropical tank, just temperate.
    The Plasma can be turned down to achieve any PAR you like. :D I didn't care for the color of the current unit over a tank, but that may be changing in the near future. Early adopters pay for being first. Also the 450 in the spectrum is seriously lacking, but who really knows if that will be problematic.

    We are doing a study now, and they do seem to grow coral. More later though, that's how studies work. To get the same PAR the plasma is about 2.5 times higher than the MH.

    There is no reason to mess with the reflector of these lights, as it is pretty built into the unit and the amount of UV these produce unshielded would make me not want to mess with it. They are working on making it so the user can adjust the size of the throw by adjusting the reflector.

    FWIW, when the next version comes out, the 41 (with the possibly better colored bulb), I am seriously considering getting two for my home tank.

    Thanks Rich. Can wait to see how this turns out.

    I saw the RB site mention of these at Reefstock(??) they said one particular reflector could cover a 48" wide tank? That would have serious sex appeal if you didn't need to dial down the intensity to get a pleasing color.

    My problem is that with this light sure its has high par numbers at ~6000k. We all know for metal halides the lower the kelvin the more efficient the light tends to be. If/when the plasma bulb is changed to a higher kelvin (when fully driven) how much will the par suffer? How much will efficiency suffer?

    Efficiency is barley effected, PAR I couldn't tell you. The funny thing is they do have ones with more blue, but they've up until recently considered those "bad bins" and didn't use them. After Reefstock I suspect they will start using more of those ;)
