Wow! That is a lot of light. I ordered 5 with 60 degree optics for my 44x24x21. I was told by both Evil and Nick at Nanotuners that would be enough. If you line 8 bulbs up they will almost touch each other down the length of the tank. Can't wait to see the effect. Are you going to use track light fixtures?
yeah this will all be on track lighting hung from my cieling
there will be 4 4 foot long pieces of track
each track will have 4 sockets on it, with 4 PAR38's on each track (total 16 bulbs)
the bulbs will be in rows of 4 from side to side and front to back, this IMO will give me all the flexability and coverage i need and want, the sockets on the track setup are moveable 360 degrees and the sockets themselves can be moved up and down as well as the track to get the desired hieght
i'm shooting to have these lights no higher than 5 inches off the surface of the water for the most PAR
I got the track setup this weekend and am placing my order for PAR38's this week, if it doesen't take more than 2 weeks to get the bulbs i'll have pics of the entire setup soon
then i will be trying to get my hands on a PAR meter so we can finally end the MH/T5 Vs Led debate, lol
i will have sps corals placed in the lowest parts of the light in my tank as well as frags in the higher light sections to give people the best idea of what these lights are capable of

well just talked to nanotuners today and demand for the bulbs is insane right now and their supplier can't seem to keep up, i'm hoping to have my bulbs in 2 weeks but who knows if that will happen, i'll update as i find out more info
I'm thinking that i don't need to light 100% of my tank and i want a dramatic look/effect and the spotlighting affect should add this to my tank, the lights will be focused on the rockwork for the most part with the spill off from the lights hitting the bottom floor of the tank instead of the walls
i'll have to see what it looks like in person before i make a judgement but i'm thinking it should work out perfectly for what i'm going for

Beeker,
The nice thing is you can always add 60 degree optics to get some spread, albeit with some loss of Par. I still can't imagine what 16 of these lamps will look like. It should be nice, but man that is some serious light. I am going to use 2 circuit tracks so that I can have 2 lighting options on each track.
I am also disappointed that Evil was cut off from giving what I thought was nothing more than good advice, unfortunately he is not the first one.

A few pics of mine
Mike
Are the top pics 12K? Do you see a lot of difference between the 12K and the 20K? I want a hint of blue but not a lot of blue.
hah, maybe i am insane but it was either 2 250w MH's with T5's or all Led's, lol
I went leds so with my insanity i easily feel 16 with 40 degree optics will get the job done, haha, i was originally going to go with 12 but i hate half assing things and have learned to do things right the first time since my main tank was kindof pieced together here and there i really wanted the 200g to be done right from the start leaving me with less of a headache to deal with after it's all said and done
i'm going with 40 degree optics becuase i mainly keep sps coral, thus i need the most PAR i can get granted i'll still be testing these lights to see how low i can grow sps in this 27inch tall tank, so i will be placing sps at the very bottom of this tank just to see what these led bulbs can do
i will also be getting a PAR meter from a local reefer after i have the setup running a week or two and then i'll have pics posting numbers as well
my bulbs were sent out yesterday i hope to recieve them by monday since they are comming from cali and i'm in ohio
i will have shots of my setup the second i recieve the bulbs and get them plugged in
the first shots of my tank will be of the right side being lit only (with 8 bulbs), since i will have to buy another 8 bulbs for the left side of the tank and don't have funds for that at the moment

For those of you guys with par38 leds do they run warm or hot to the touch? do they direct/radiate the heat into the tank?
I got a 6x54 ATI sunpower T5 fixture and while it doesnt add too much heat into the tank with the active cooling it does it to the ambient like a small radiant 324 watt heater.
Would 6 of this par38 units generate alot less heat into the tank and ambient VS the ATI?
I know we are comparing only 120 watts of LEDs Vs 324 watts of T5s

Yes definitely less radiated head. I can't speak to whether they get hot to the touch ( I imagine they do a bit ) but LED is much more efficient than t5 so less of the electrical energy is lost as heat. So not only would there be less heat even if you had 324W of LED, you're talking about 126W ... less wattage AND more efficient double whammy in terms of reducing radiated heat as far as I understand.

I would like to here from someone who has both a 12k and a 20k and get their impression of the difference. Pictures of each of them would be great. I need to complete my order so it can ship but I am undecided on the temps. So far I have 4-12k and 2-20K but I can still change the order since I am waiting for the optics. I want a crisp white with a hint of blue, but not windex blue. Can anyone help?
