I need to know if type SJOOW flexible cord is a acceptable wiring method for low voltage lights in a hard ceiling. Can it be used for a class 2 circuit?
 
Yes thats what is getting me. But 400.7 says it can be used for wiring luminaires. I guess that just means for pendant lights and such. In the 2005 nec art.411 now states that a class 2 wiring method is acceptable for low voltage lighting.
So really I need to know if SJOOW cord is acceptable as a class 2wiring method.
 
Yes i did. Basically I just need to know if SJOOW cord can be used on a class 2 circuit.
Art.411 in the 2005 NEC states that class 2 wiring methods can now be used for low voltage lighting.
 
If you are referencing the 2005 NEC, Art 411 does permit the use of Class 2 wiring methods for Class 2 lighting ckts. There is a Caveat thought...you will need to reference Table 11(A) in Chapter 9. This table restricts the use of Class 2 wiring based on the info you find in that table. Therefore you may still be restricted to using Chapter 3 wiring methods depending on the Class 2 source you are installing.

400.8(1) & (5) is where I was headed.

Have you read 411.4(A)(1)?
 
There is a change that has been accepted for the 2005 NEC that will relax the requirements in 411.4 by permitting Class 2 wiring methods to be used and concealed within walls, floors, and ceilings where the power supply is a listed Class 2 power supply and the wiring is installed in accordance with 725.52. There may be a drawback to this new permissive rule that should be considered. Tables 11(A) and 11(B) in chapter 9 do not permit a Class 2 power supply to have nameplate wattage that exceeds 100 VA or amperage that exceeds 5 amps at 30 volts or less. Comparing this 5-ampere value to the 25-ampere and higher wattage permission granted in Article 411 for low-voltage lighting systems will severely restrict the use of Class 2 power units. Class 2 power supplies will, however, provide an alternative cable that can be installed inside walls, ceilings, floors, cabinets, and other spaces where chapter 3 wiring methods were not easily installed.
 
It was in a Chili's restaraunt remodel. I hired a guy who has done 15 of them and thats what he did on all of them. I did not know he was doing it until after it was done. He is now doing one in Jacksonville,FL. I told him that you can't do it and he still did the same thing on that store. So oh well.
I replaced it today with 12/2 MC cable. It passed and everything is all good. Thanks for the good feedback.
