Hi, I need some I disconnected a ceiling tube light but the switch controls light in a different room but I now I can't get the lights to work in the other room

you will need to join some or all of the wires. did you take a note of how it was wired before you disconnected it. if not you will have to get someone with the correct test equipment to test it.

This question gets asked many times a week.
To save having to repeat the answer over and over again it is all detailed in the WIKI.
The lighting information is here http://www.diynot.com/wiki/electrics:lighting:lighting_circuit_layouts
If you cannot follow the diagrams and do not have any test equipment then you'll need to get an electrician on site.

I did test but all were generating power there's 4black wire and 4 red I knw one red is switch but can't diagnose which one and don't knw which black is the switch..!
The wires dont "generate power"
What are you testing the wires with.?
Please dont say its a neon screwdriver..
What did you test with?
I would suggest when testing you use the correct procedures and approved equipment, if you are not familiar with the set up, also test dead first.
Prove the circuit is dead and test continuity of the conductors, this should give you all the information you need.
Or a glow-stick
No I used a digital tester.
When I opened it one black and red wire was connected together isn't that dangerous?

Yes very dangerous to you so I would get someone that know a thing or 2 to come help you.
And what did you do with it which led you to think that " all were generating power " ?
Did you not read this:
?
You should read these as well:
It is if you opened it up without isolating the circuit and proving dead!
Like I said the safest option is to do the dead tests, this would confirm what the cables do.
You have been offered links, that help explain how lighting circuits are designed and function. You must read these to get at least a basic understanding.
You have 4 reds, normally they would be live/line conductors, this could be a combination if you parted them, of:
*permanent live (from supply (directly) or looped in)
*loop/loops, could be more than one, to next light/lights/or other appliance on circuit (normally this should be dead when disconnected)
*Line to switch
Then 4 blacks:
*3 are likely to be neutrals (looped in)
*and the spare, the switch return (this should be sleeved red)
But really should not take this for granted, as it may not have been installed this way or correctly according to identification of core colours.
So some dead testing would be required to confirm what task these cables are performing.
Doubt it. Black is a colour and red is another colour. Why would it be dangerous?
Do look at the link I sent you. If you look you may see lots of reds connected to blacks (and browns to blues)
It depends on what function the black and reds have.
