yup just one, mine is propped up about 4 inches above my tank (haven't gotten around to hanging them) and the light reaches the edges, i'm using the 120 optics. I got my mushrooms on the edges and they are ****ed about the amount of light they were getting had to move them to the bottom of my tank. I just have softies and LPS so i don't know if you will want more light, but i find with the IT2080 being 32" long it works well centered over my 4' tank.

I have the IT2040 over my frag tank and the colour and ease of control with the remote is to kool but i wish i could take a pic to show how the colours on the corals pop but i run it about 16k

Ok. Here's a rookie question... You said you run about 16k. Kelvin is adjustable? And how do you know the value?

You can do a custom set up and adjust the blue and white ratio

I have an IT2040 as well but haven't got it running over a tank yet. Picking the tank up later this month from concepts. The light is great, its full spectrum and customisable with the built in control. A little more expensive that the d120 but a little more controllable.

I have the d120 over my jbj28. no complaints. good bang for the price. getting decent growth.

thanks for all the input.

I really have no reason for not trying these.

My tank is almost cycled... from the rebuild. No corals in the tank... so its the right time to switch lights out.

Probably sell my 48" 6 bulb tek. im worried, as the tek is good.... but I hate buying new bulbs. Just spending too much money. No money on bulbs = more money for fish. :mrgreen:

Did anyone think this D120 is not bright enough? I run both channels at 100% and still my 4 x 39watt T5 is brighter. My tank is 3ft x 2ft x 2ft tall. I run 1 D120 about 8 inches above the water. The light doesn't penetrate deep enough. Does anyone in lower mainland have any of this I can take a look or compare? Maybe mine is defective

One d120 won't cover 3x2x2 which may be the reason why its not as bright. That being said I have the same dimension tank and is plenty bright with my it2060. I'm in surrey if you want to compare.

Yea from my research.... 36" is over the absolute max spread.

Anyone else find them not so bright? I'm looking at my T5s and starting to get hesitant to switch.

Everything says "go for it" but my T5s are wonderful. Just tired of bulbs. Having a high quality fixture and then replacing it is a tad scary. Lol.
