btw, as far as I'm concerned high tech stuff like this pays for itself on day one if it works the way you hoped it would, looks the way you wanted it to look & makes you happy.

I was thinking a road trip to Mission is needed at some point. :wink:

I only get 2300 for bulb replacment and that is if you go with 3 bulbs. 2 bulbs can light a 6 foot tank effectivly so that would only be 1600.00 ish.

if you changing MH more than once a year your throwing away good money.

from what I read there realy isn't much along the lines of energy costs, we will wait to see if you can still go with out a chiller but the ability to change the light color is cool as long as all bulbs are still on when you do it.

Next time I am in Vancouver, with out the wife maybe we can set it up and I can do some PAR measurments.. would be interesting to see the practical output of them.

what did you use for your "rock poop"?

Steve

I'll be waiting untill these units are mainstream before I'd even think of trying them.

I haven't seen a pic of the lighting yet that has given me the urge to get them.

I'm watching to see what results you have with corals. :)

I am a Res Sig Op working with CMTC at OPFOR, I will going reg force in the summer/fall I will be changing to bin rat though.

I have always heard to change you MH every 6 months. I have used one for 18 months in the past though.

Welcome anytime.

Way to go. I am looking at starting a reef aquarium and I to am very interested in the LED's. When are they going to be coming out with the
400w? These Led's should last you 12years approx., and when you consider in the cost of replacements bulbs in a different fixture I don't feel there is much difference. You also mentioned the Giesmann fixture, but for the one with the micro processor, the LED is cheaper so there you go.
Please keep us posted.

any updates?
