Is that price with a fancy controller? That is robbery if not. If the LEDs are all dimmable and can display different light conditions, then there is a lot of support electronics needed to do that. Still too much money. I guess I need to get into the LED business. It should be about 2-3 bucks per 1 watt led. 2 watts should be from 4-6 bucks each. A 100 watt LED panel with 100 1watt LEDs without fancy switching, just on or off, with heat sinks and fans should cost from $250 -$500 delivered.

No wonder so many people shy away...at that price I would to.

When I get my next batch of panels in, I will take some photos. I am considering importing these in quantity as I have had such good luck with them over the past year. I should be able to offer a 150watt LED panel equivalent to a 300-400 metal halide for as little as $350. Any interest?

I have kind of had the same question on my lights. I think I am going to go with led or my 60 gal.(24 in deep). This is kind of a side question. Should I go with one 48" led fixture or 2 20ish in fixtures? My tank has a divider on the center of the hood. Any suggestions? Also any reviews on marineland led fixtures?

I don't think it matters as long as you get the coverage you want. I cannot comment on the Marineland LEDs as the expense of these units was way out of my price range. I went with a Chinese manufacturer (I know, shame on me) that import the panels to me for a fraction the the price of fixtures like the Marineland. They are not fancy, but they work fine for me. They grow soft and hard coral...what more do you want?

it does matter how many LEDs you have, also the reflective lenses make a difference also. as well ALL LEDs are dimmable but the drivers need to be dimmable to be able to function the way its supposed to

for your 60 i think two 20LED fixtures should be enough. as

I have not herd anything good about the marineland ones... I think they use lower powered LED's so they won't penetrate as well/be as bright.

The one that I am looking at has 8 1w 10000k led and 4 moonlight led. Now this is for the 20in one. I'm just really looking for a good light that can penetrate a 24" deep tank and allow me to keep some soft corals bottom to mid way and maybe hard corals at top of that tank. Ie with in 6 to 10 in.

I don't think that is anywhere near the number of 1 watt LEDs it will take to grow coral, except in a very small nano reef. My recommendation is for 10-15x that number for a tank that is 24" deep, but it depends on you total gallonage and coverage you want. I have seen these lights on Nano tanks and don't think they are sufficient for even a 14 gallon tank.

This is why LED gets a bad rap sometimes, it takes total wattage to do the trick. 8-15 watts of LED is not enough except for a very little tank. Again, I would use at least 2 watts of LED per gallon, mixed 1/3 actinic blue and 2/3 bright white. The more depth, the better the reflector and/or more LEDs it takes.
