How far from the tank should the fixture be?

Mine was about 8 inches from the top of a 36" wide tank and got full coverage

Atleast 8 inches from the water if not more. It's almost like two spot lights.

Mine is a couple of feet away from me and a little above. I have had mine almost 2 years no need to replace bulbs yet.

no, you would need no shorter than 72" lighting system and if your tank is shallow.

The fixture uses the 4 feet T12 40 watts fluorescent tube, that you have to buy separately. The wattage is per tube.

i use a 2' 4 bulb t5 fixture. with 6" exhaust just pulling thru bottom vents. works great. to use hp/mh i would suggest a 6" cooltube type fixture.

The bottom of the fixture is about 4 1/2 inches. I run both bulbs at the same time all day long. But only keep the red one on at night. I've had no problems.

I use it indoors as a fixture for fluorescent lights for my reptiles. I agree with Carolyn L that it would be ok outside away from water.

About 3 feet. That said, it was poorly constructed and I replaced the fixture after only a few months.

This fits between post and light fixture. The problem I had was trying to lower the sensitivity

You will need at least 2 for sure. I have a 30" tank and one just barely does it. If I had room for another one I would put acsecondbon the tank to get better light at the bottom.

It'll be maybe 2cm lower than with the cover on. The filter assembly sits right under the cover, not to mention when the built in light is flipped up, add another 3 inches to the tank's overall height.

I get just under 4 inches from bottom of base to tip. 3.25 inches above the metal plug which would extend out from your fixture.

The actual fixture isn't critical. You might want to try it on one and then on the other. One of the things you need to consider is the location of the power outlet you need to power the pump. I placed my pump at what I thought "might" be the greatest distance, but more so where I could easily find an outlet...under the kitchen sink. The only thing I caution is the sound of the pump. I can't hear it, but my wife has complained that she hears it and it bothers her, but she likes the hot water at the kitchen sink!

Brian, not sure about your question, but I can tell you this, this light is a very powerful Baby :) you have to keep it at least 4 or five inches away,, MORE then the instruction's recommend. I have several different sizes of these lights and they are all like that, VERY NICE LIGHTS I LOVE EM :)

My tank is 17" tall, and the light is so strong I only use it at 65%. I think you would be fine with one at 80-100%

Depending on how high you mount the light above the aquarium and how intense you want the light to be can determine how much coverage you need. If you aren't growing corals that need a ton of light, 1 light would do probably mounted 10 to 12 inches above the aquarium I would guess.

I agree. The light doesn't generate any heat so it can be placed close to your plants. A few inches away will allow your plants to receive the full spectrum of light generated by the different colored LEDs .
