I will get excited about LEDs when the manufacturers post comparative numbers using a named lamp and reflector as well as distance from the fixture.
This deal of saying the LED's produce as much light as a 20K halide is a load of crap. There are some pretty pathetic 20K halides out there. Give me a comparison of a XM 20K 250 running in a PFO parallel reflector 20" from the fixture THEN I'll THINK ABOUT IT.

I still don't have the tank set up but the fixture should give me PAR in the 150's or better at the bottom, does 170's with no water in the tank.
This is what the dirty tank looks like empty with the lights on

Those puppies seem to peak near 420nm!

It's a mix of 52 royal blues that peak around 450, 8 Warm Whites that or probably around 3000K and 24 6500K Cool Whites but they are the higher output XPG emitters so make things a lot brighter. The look isn't as blue as the pic shows, I'd guess somewhere between a 15K and strong blue 20K halide.

Not sure why this question is in a 5 year old lighting thread

Time for a Lighting update. Lighting moves on. Experts, Share your knowledge please about the newer LEDs and their progress.

I;'m being sold on LED's more and more every day. different people have different ideas on color balance but if you want max par per your watt of power they are there. When Grim built his fixture 4 years ago it was hard to find LED that gave more than 80 Lumns per Watt. Today there are loads out there pushing the 140 limns range. Bot Philips and Cree have some in research pushing 200 lumns per watt and claim they will available to the public by year end.

I have gone to all LED's after about 3 years of experimenting with them. Every time CREE comes out wth a new series they get better and better for the DIY builder. Out of the commercial systems out there there is such a mix between outright garbage and fantastic systems it is unbelievable. But unfortunately price is not any indication of quality as far as your Corals are concerned. You can get a $200 system that will outperform some of the $800 systems, and you can get a $600 system that will preform the $1200 systems. Be aware of the extra bells and whistles like multichannel dimming and moon light phases that add price to the fixture without adding any value to the corals. Make sure they are using quality LED's And keep in mind that a 10 LED's running at 1/2 watt each may be more power efficient than 1 LED running at 6 watts but the cost to build the system is probably 5 times more.
Personal experience is a well designed balance of LED's will guve you the same results if not better than HO T-5's running twice the Wattage without, additional cost of regular T-5 bulb replacements. and when you switched form Metal Hides to T-5's you probably already saw the savings on electricity already. Note if you PAR minded I have no problem getting 200 PAR on the substrate of 24" tall tanks at roughly 2 Watts per gallon with the latest LED's. Some day I suspect it will imprive to be able to do this at 1 Watt per Gallon.
