Question for you lighting gurus. What makes a low voltage fixture better or any different than a line voltage ? Thanks in advance

I am not convinced they are any better. I think the availability of low voltage Mr-16 bulbs with many different degrees of angle may make them more desirable but other than that they are not better.

We pipe runners may see things differently Dennis. The advantage for us is not in the fixtures themselves, but in the installation. Around here we can't use romex, only bx. For us, low voltage and remodeling is a much better product. The advantage is in the fishing of the wiring. It's exponentially easier to fish CL2 wire than anything else.

If you talking about a fixture with a self contained transformer, then Dennis is right, very little is different. If you talking low voltage under cabinet lighting, for instance LED tape or pucks, this wire makes life easier from a basement mounted transformer to the fixture.

So you can run class 2 without conduit????

BTW I was assuming low voltage with integral tranies.

Our article 411 in the Chicago code book has nothing like the 411 in the nec. Says nothing about the cl2. But what about 411.5 (2)

(D) Insulated Conductors. Exposed insulated secondary circuit conductors shall be of the type, and installed as, described in (1), (2), or (3):
(1) 
Class 2 cable supplied by a Class 2 power source and installed in accordance with Parts I and III of Article 725.
(2) 
Conductors, cord, or cable of the listed system and installed not less than 2.1 m (7 ft) above the finished floor unless the system is specifically listed for a lower installation height.
(3) 
Wiring methods described in Chapter 3

NEC 725.24 Mechanical Execution of Work. Class 1, Class 2, and Class 3 circuits shall be installed in a neat and workmanlike manner. Cables and conductors installed exposed on the surface of ceilings and sidewalls shall be supported by the building structure in such a manner that the cable will not be damaged by normal building use. Such cables shall be supported by straps, staples, hangers, cable ties, or similar fittings designed and installed so as not to damage the cable. The installation shall also comply with 300.4(D).

Here in Chicago our article 411 has nothing about cl2 compared to the 2011 NEC. What about 411.5 (2)

(1) 
Class 2 cable supplied by a Class 2 power source and installed in accordance with Parts I and III of Article 725.

I don't have a Chicago code, but this is from you own quote, which sites my quote from the NEC

Almost none of the low volt lighting I do is class 2.

I work commercial jobs with engineered prints. I don't choose. Try finding class 2 track lighting or class 2 recessed lighting.
That's what I meant in this thread low voltage recessed lighting

LowVoltage

It's not that one or the other is better, it's what you can do with them. Low voltage lighting has better beam spreads to accent the objects that you are trying to light. Line voltage is more for general illumination.
