The eBay taotronics. I've seen them there, but never see sizes. I've never used LED, so I'm not familiar with what I would need.

They are good for about a 2 x 2 area, 30" deep or so. People raise them up and light entire 36" tanks with one of them, but I would want 2.
So, if you are talking about the 8 foot 240, then you want 4 of them. If you are getting the 6 foot tank, You need 3.
I recently had a 7 foot long 265 and was able to get away with 3 of them.

The 60 degree lenses are only for deep tanks. You want the 90-120 deg. for most normal installs unless you want the fixture way above the tank.

60 degree? Don't you mean the opposite? I would use them with the 120's personally.

LEDs started out at over $700 for a panel. Chinese prices vary a lot depending on shipping costs. We just got spoiled with $120 panels. There are some bargains still out there. But the real picture can be your power bill over the years. Even with LEDs my system uses about $7 of electricity, per DAY. When I used MH it was quite a bit more, so over the short term LEDs pay for themselves, fast. For you horrified with the power bill here is how it works; (Total of up to 2500 watts per hour, average electric rate of $.13 kWh.) Fish room is in basement, DT is 10' above. Big iwaki pump lifts water for the past 23 years. Several other big iwaki pumps power the rest of the system downstairs. So LEDs is only 1/3 of the total power bill. I also have a chiller running as I like to keep the tank ultra stable at 77 degrees.

I just got two 120 watt panels from a Chinese company that really did a fantastic job. They have 3 channels, 26 LEDs each on 1 and 2 and 3 LEDs on 3. Channels 1 and 2 have knob dimmers and channel 3 is simply on/off. They also have built in digital timers which control all 3 channels. They are heavy duty metal casing as well. They do custom light setups as well. I customized mine to be very similar to the aquailumination hydra fifty two lights. I am very pleased with them.

Just picked up two AL09 120w ****able units on Amazon for $169 each + free shipping ... Less $10 off from the seller for a reef discount. Figured I might as well get them now before prices keep going up.
