I was messing with my outdoor Flood Light and broke a part and the manufacture doesn't sell the part. So I tried JB Weld twice now and it doesn't hold. The part is basically a piece of 1/2" round tubing (cast). Is there anything out there better than JB Weld?
Anything better than JB Weld...

For round tubing a sleeve with a couple of grub screws would probably work better.

A better description is 1/2" tubing that isn't completely round....like a quonset hut. Note... Wires run thru it also
Not quite as big

My suggestion would be to figure out what material it is, then google for that. JB Weld's FAQ says that it won't stick to polypropylene or polyethylene, so my guess is that it's one of those. You might be able to use a solvent to bond them back together.
Gorilla glue will stick to things JB will not. It can be handy to keep around.
My first instinct though is what Trav said. Sleeve it with something like tubing (heat shrink even if it doesn't have to take much weight or stress)? Wrap it with hose clamps, etc. Then spray paint it if necessary to camouflage the repair so it doesn't stick out if it bothers you.

I fixed a Caterpillar engine block with this about 30 years ago. Engine still runs today. I haven't met anything this won't stick to.

If you want a quality epoxy, avoid any "5 minute" or "fast cure". DevCon and MarineTex are among the top easily available brands.
But I agree, it's probably the wrong tool for the job, at least using it alone.

Correct.
And 3M 2216 A/B is better than JB Weld, but it is $$$$$$$$$$
Take a small piece of copper tubing 2"-3" long and squish it until it fits inside the half round area. ROUGH UP ALL surfaces where glue goes, then apply adhesive.

Use a quick set cheapo epoxy from horror fright, 8lb (+/-) maul, 3years now. I'm sure if used correctly it will hold. I had to use a hair dryer to boil air out of jb before, but it was to seal a high pressure, oil/water separator in a cup developing cracks. Yours just need good prep and good pressure for a few hours.
I ended up getting JB Weld Steel Reinforced Epoxy which takes 15-24 hours to cure which is key to making it work. I got the light back together without it breaking. This stuff dried rock hard compared to the soft Kwik Weld that didn't work.
The Prep:
1) Used the Dremel to rough up the area down to metal
2) Rinsed parts with water
3) Cleaned area with Q-tip and alcohol
4) Let the JB Weld set-up for about an hour before applying. To runny to apply after dispensing.
This is what I used >>>>>
