Junction Box for a Flood Light

I think the key point is not so much the lamp has to be mounted to a box, but the electrical connections have to be made in a box. If the lamp housing isn't rated as a junction box, then one has to be used. I'm pretty sure passing lamp wire through a wall isn't up to Code.
 
This is what I'm starting to realize. I thought there would be some way to pass the wire through the wall and into a junction box. I guess the next best option will be to find a junction box that matches the color of my light fixture so it sort of appears as one unit.
Not much of a colour palete in electrical boxes. I suppose you could prime and paint it - don't know if there a Code rule against it. If it's outside, it wants to be weather proof rated.
 
The pancake box can be installed flush. And the fixture hardware attached to it.
His best bet is to get a fixture that works without a box. But I have recessed a few pancake boxes where no recessed box was in place.
It sounds like the OP is reluctant to cut a big hole in his siding.
 
Well apparently in their own installation video they are using the same junction box that I have and they are simply recessing it into the wall so that the light can mount flush on the outside. This is basically what I was wanting to do in the first place. I was just hoping not to cut a massive hole in the side of the building. But I guess it's not that big of a deal. I'll just cut a hole the size of the junction box and mount the light flush to the wall. Then seal it with silicone.
Okay, I misunderstood - I thought you wanted to avoid that. When you recess the box, the weather seal is made against the siding surface rather than just the thin edge of the box. Hint - when you silicone or whatever the edge of the lamp housing against the siding, leave a gap at the bottom; that way any water that does get in has a gap the drain out.

As GrayHair mentions, the box box has to be secured. If you have access to the wall behind you can block it somehow; otherwise, old work boxes have a variety of tab and wings that lock the box to the back of the siding.
