Alternative to traditional temporary lighting?

Idk if ive ever used a string light with ground in it. I was wondering if i could just buy 12/2 lighting cable and run that to a few cob lights. Its still 600v rated just most arent ul listed for that purpose. But a 1000 ft spool of this cable is 150$ or so but that in romex is astronomical at around 500$.

The last temp lighting I bought was 100 feet, made with separate black and white #12 wires and a socket every ten feet.
 
You can put a "cob light" into the screw-base sockets of the usual string. What don't you like at the strings? (and what "12/2 lighting cable" are you talking about?)

BTW, read article 590 if you haven't already.
I dont like the string lighting because the base every 10' makes it hard to pull back down when its time for above ceiling inspection and power gets turned on.

Its a southwire wire and type is

LVLL/ULEC Landscape Lighting​


Its 100$ for 500' and is rated up to 150 volts. Its rated for direct burial and it looks basically like lamp cord or speaker wire.

Ive read article 590 and this is what i dont understand it says all temporary installations need a ground yet ive never seen a string light with a ground in the yellow SO cable. I read the version of EC&M which they usually do a better job explaining but ill break out my 2017 codebook when i get home.

What would the ground conductor be connected to? Isn't everything plastic?

Brass shell, paper-lined sockets, or other metal-cased sockets
shall not be used unless the shell is grounded.

Not what it says. 590 covers temporary installations, not just lighting.

These are the ticket. They have an outlet so you can chain them together with extension cords if you need to.

Yea i read that part but i didnt see an exception for lighting which is why im confused it said all branch circuits must have ground fault protection maybe i just misunderstood and that just means lighting must be gfci protected but with no real ground i dont see how its truly gfci protected.

I was thinking of just making some with t condulets and screw in bases that way i dont have to worry about damaged cords and just replace the low voltage cord when the time comes. From all the jobs ive been on i havent been on one where the string lighting comes back out if the ceiling uncut.

Ive used them before tho and they are nice and bright the clasp on them is also super handy.

These aren't string lights. Theyre individual fixtures with a feed through outlet. You can run a bunch of them together with cheap 16ga ext cords.

Your low voltage landscape wire is not a listed wire or cord type that you can use for line voltage temp wiring.

Milwaukee makes a similar portable high bay that is made to be hardwired, its often used with MC cable, but its twice as much $ as the one i linked,

The ones i used had a cord on them and OSHA dorsnt approve of aftermarket cord ends that is why i wanted to find a cheap alternative to traditional string lights because they are costly and the bases every 10' are impractical for my use case . But after reading 590.4 some more i see only hard use listed cables and nm cable are useable so i just have to scratch off the idea of using any other type of cable as much as i wish i could.

Romex prices and emt are both up over 60% over the last 2 years it is crazy how much the material aspect of jobs is now cost wise.

Ah ok so the issue with that first light I posted is when its line cord gets damaged you can't replace the cord end on it?

I wonder if theres one with a 5-15 inlet instead of a cord.
 
Not much more than the parts without the cable, then figure in the cost to assemble. Even if you remove every other cage and screw a blank into the socket, you're still probably ahead for many uses. (You can also get, or make, 5-light strings.)

What is your use case?
It would be residential. I just thought itd be more cost effective to have a permanent reusable solution instead of the strings. I think they would work out to about the same cost so i guess im better off with string lighting.
 
Not trying to pick on this, but why wouldn't the strings not be reusable? They're made for it. Just like extension cords, treat them right and they'll last a long time; I have some in the trailer that are probably 15 years old and have been up&down 3-4 times a year.

For cost- under $15/socket, sometimes under $10/socket, and they come with the required lamp cages.

Well strings are sorta reusable.
Charge more from the customer so reusing temp lights from job to job isnt so critical...
I always liked the prefab (no mc, romex,cords) because from the first to the tenth floor all the lights end up in the same spot, and it looks sweet from the freeway. A small detail, but a important one- when everyone in town notices all the lights on every floor are evenly spaced and vert aligned..
