do you need two or one of these to hang a 4 foot 4 tube light?

one pack comes with 2. You need 2 to hang a light so you need one pack per light.

I did use one to hang a two bulb light but had a problem keeping the fixture from swinging,when I added a second hanger it was perfect balance....personally I would always use two..

I use two per light for stability and the flexibility of being able to raise one side higher than the other for the occasional growth spurt.

You can use as many or none of the extension rods. Without any extension rods, the light will still drop down from the ceiling about 1 - 2".

They are very light, so I used 4 3M hanging strips. 2 on each side, and they worked great.

You get two V-clip hangers that attach to the body of the light and you need to have something to suspend it from as well as something to suspend it with. Meaning no ratcheting rope hangers are included and it is not free standing.

No you need a mounting bracket. It has a bracket on the light with a single bolt that will mount to the separate bracket you get for your bars.

Yes, you'll need one for each line. They are left on the line and as the line gets slack, you can tighten again.

It's two I got them to hang off my light pole. Make sure you get the right size. These were a little two big but I got them to work.

I believe the answer is yes. And if for some reason you feel the light is inadequate, just use two.

If you have room you can mount them, Besides the mounts that come with them the Rigid website has various mounts for tubes in various sizes. They come with a very good wiring harness that is easy to hook up. You may want to get the lights and play around with them before you mount them in different locations to see where they not only fit best out of the way but also don't have shadows from something blocking the light beam.

I bought mine just about the same time as Gregory R, and got only two 2' flimsy chains with S-hooks on each end. No possibility of hanging as the picture shows unless only 1 foot from the ceiling. There are three attachment holes on each end of the top of the fixture, two obviously intended for hanging as shown, and the other for hanging with only a single chain.

I had an electrician hang the lights -- I'm afraid I don't have the answer to the question. I will try to get an answer for you.

Light works great and is quite bright. How wide is going to depend on how high it is mounted. I would think two lights would give you the best result.

I don't know. We specifically bought the lamp for the purpose of using it with a chain. We looked everywhere (Lowes - Sam's etc.) and all of the lamps they had would have required a lot of work to hang them with a chain. So this is the ideal (inexpensive) solution to those who want to hang a lamp with a chain.

assuming this is a freshwater planted tank, the good thing about hanging fixtures is you can adjust the height of the fixtures. I would saying having two would be ideal, and give an even amount of light over the entire length and depth of your tank. having only one would give you enough light in the tank under which the light is positioned. but having two would give you more even light over the entire tank. Unless you want to create different sectors of your tank for low light and high light I would use two. With two you can still create those different sections, by adjusting the height of each fixture, and also give you the ability to change different areas of the tank any time you want. assuming this is a freshwater planted tank, the good thing about hanging fixtures is you can adjust the height of the fixtures.

I didn't hang these fixtures. I had an electrician so I wasn't watching to see how much was left over from the cord. We have them hanging from a vaulted ceiling so the length is very long and there was some extra left over. They are beautiful hanging over our island

There is only one place to attach a wire. I suppose you could double up a couple of wires and attach them that way, but the unit is meant to support just one. You could also use waterproof wire nuts or waterproof butt connectors and add a second wire that way. The way the lighting people look at it, the question is how many lights will the unit support, which is controlled by the wattage of the lights.

I have a mini dual lamp hanging on the end and a single lamp about half way. The stand holds them just fine. :-)
