That's an understatement. Good luck selling the need to buy one of these to the finance department!

Hi,
Congrats on the new light. I too had/have (in the closet) the Solaris (72”), the Vertex looks much more promising. Was there a particular reason for switching from the PowerModule to the Vertex LED? From your photo, in my opinion, your tank looks better with the PowerModule; but, I’m a bias PowerModule owner  Looking forward to seeing how your coals respond to the new light source. Very nice video by the way.

IMO the PowerModule is hands down the best T5 fixture but for me T5's just don't look natural at all and I've tried many bulb combinations... The Vertex gives the tank a more natural look, there is no light spillage as opposed to the PM and the shimmer is back! Also, the Vertex controller ramps up and ramps down the intensity (rather than just on or off for T5's) and the fish and coral appear to enjoy it much more. The PowerModule is ideal for a frag tank to aggressively and efficiently grow coral but in my main display tank I want to come as close to nature as possible. -TDF

Love the way the fixture looks!! Can't wait for the readings. You have given me much to think about, I am in the process of upgrading my aquarium and was planning on getting the AI LED. Now after seeing this one I am having second thoughts. The readings and the cost will probably be the deciding factory.

Below is the non scientific Vertex Illumina SR 1200-200 PAR measurement taken with a Apogee Quantum Meter. My tank is 18" tall and the fixture is 6" above the surface.
White 100% - Blue 100% - Royal Blue 100% 759 about 5mm below the surface 484 On left frag rack 392 At top right coral colony 242 Center of Red Monti 227 Center of Clam 185 Front Elegance Coral 214 Bottom right middel of tank 148 Bottom rear of tank  Last edited by TheDogFather; 07-13-2010 at 01:07 AM.

that just blows me away that those little LED give off that much PAR.
How high is that light from light to bottom of the tank. what was the par on the T-5's I hope that this light has promise not like the other one wit the problems it had with warranty circuits boards LED's and unit blowing up

Hey Mike, can you show that from the end of the tank to give an idea of the front-to-back spread?

Any updates or more then and now photos? Personally, I'm not super impressed with the PAR readings you showed so far. For optimal growth of SPS you want between 400 and 500 PAR. My DIY LED array achieves that in the middle level of the tank (10 inches down my 20 inch deep 75 gallon) at less then full power with the array 6 inches above the water. If I turn it all the way up and lower to 3 to 4 inches above the water I get way more. I get well over 250 PAr at the sand bed 18 or 19 inches below the water surface.
Your clam may do alright but as I understand it clams need 250 to 300 PAR (I may be wrong on that but it's the number I recall). Quote:

I'm not going to get into a PAR contest with your DIY fixture, I get excellent growth (at 50% power I might add) and my clams are growing very well. The 48" Vertex Illumina LED comes very close in PAR output to my previous fixture, ATI PowerModule with 8x54W T5's and that fixture is no slouch. I'm guessing your DIY uses optics to achieve higher PAR values but at the cost of spread so you'll have to hang it high to get decent coverage thereby negating all that extra PAR... -TDF "Stoney corals appear to photosaturate between 400 and 500 PAR so having 700 or 1000 PAR is probably pointless other than for bragging rights. I doubt it will do the corals much good." -Ron99 Last edited by TheDogFather; 09-01-2010 at 01:15 AM.
