UV spikes up to 420 and probably higher.
Have fun with that, this discussion is going nowhere. :deadhorse:

I would never go back to Halides. LEDs are now just as cheap, last longer, seem to get better PAR, and do not have the issues of heating up your tank. LEDs for life.

Really now:hmm3:
Just as cheap....uh, no, not even close.
Last longer, well, that remains to be seen. I have metal halide ballasts that are 10 years old and still running strong. The life of the components in these electronic fixtures is yet to be determined. I know folks with 1 and 2 year old fixtures that are having electrical components fail them. Fortunately for them, most of the LED companies are taking care of them because they don't want the bad press.
Don't have the issues of heating up your tank, but, you have to run heaters to keep the water at normal reef temperatures. So, that electricity is often negated.
alot of people told Thomas Edison he was beating a dead horse too..............................
Thomas Edison didn't parade false statements around as fact. Anything over 400 nm is NOT UV, and there is no arguing it. 400 nm is the worldwide scientific community's recognized limit. To say otherwise is not only absurd, but also shows a distinct ignorance regarding the topic at hand.
That's why I'm done with this discussion, and that's why I made the dead horse reference.

Sorry Dave, but Shallow Planet is right. Just because many of the top led names like EcoTech, AI and a few others continue to ask crazy high prices, doesn't mean you can't get high quality leds at MH competitive prices. There are high quality leds out there that are cheaper than MH. I think the EverGrow line of products will change the entire price structure of the led market over the next year or two. Three years ago I paid $1100 for an AquaMedic MH for my 180g DT, last year I got 2 EG (EverGrow) leds fixtures to replace them for just under $700 ($340 ea). Ah... if my math is right... ahhh... oh cool, the leds are cheaper than the MH. Hmmmm.... :eek2:
Gee Ron All you do is promote Evergrow and you are just putting them up and "are 99% sure they will work". Please wait a while before and then give us a before and after picture.
Is this still going?
If you go back and read it from the beginning you will find that most of these questions have already been churned through several times.
In the end, light is light. MH does not produce a different type of light than led. A garbage MH will give exactly the same results as the equivilent garbage led fixture. A top notch MH with a great spectrum will give exactly the same results as the equivilent top notch led fixture with a great spectrum.
Led's will NOT save you huge amounts of money on your electricity bill unless you are running a chiller with your MH's (4 bucks a month for me....better than nothing I guess.) If you are running a chiller your savings could be substantial.
Led's DO work wonders on the temerature of your tank. Mine used to jump up to 2 degreees centigrade (roughly 3F) and now it does not.
There ARE a lot of really awful led fixtures out there, some of them very expensive and tooted as industry leaders. You do very often not get what you pay for when it comes to led's.
In the end the 2 things that will make led succed are how much light you can get out of them and how little heat it projects into the tank. THe fact that you do not need to change bulbs is nice too. Once these slow pokes can figure out how to get a really great full spectrum multi chip it will for sure be the kiss of death for MH.
Not sure what the cost savings on converting to LEDs really is long term. How many upgrades will I have? If you go Chinese lights will they still be around? My son has become a DIY with the issues he has had with D120s. I suspect cost saving are small.
