Installing an outdoor wall sconce.

Hi, I need some advice.

I want to install a new wall sconce (like this:

66) on the exterior of my garage wall, where no light was before located. The garage wall is unfinished concrete block, both interior and exterior. I already drilled a 1" diameter hole through the block and inserted a 1"dia schedule 40 PVC electrical conduit through the hole. I am going to need a junction box, somehow on the outside, that would be covered by the wall sc once's collar. Unless it is the only NEC-approved method of installing an outdoor wall sconce, I would rather not cold-chisel-carve out a notch into the exterior of the block that would be big enough to insert (from outside) and bury a junction box within the concrete block. Is there an elegant w ay to do this? Is there some type of prefab mounting block that's deep eno ugh to accomodate a (for example) 1"deep junction box within it? All advice and references to examples are greatly appreciated.

Thanks Theodore

There are special shallow boxes only about an inch deep that you can use ou tside that might not be too deep for the base of the lamp fixture. I have seen them both in plastic and metal. I would go for the plastic if it is e xposed to the weather.

Although it would be against the rules of the NEC it would not be against its purpose if you didn?t use any box at all since concrete block is not going to burn if there is a short. If you want to stick to the rules you might buy a paving stone and make a hole in the middle for a box.

Others have already suggested the shallow junction box, which is perfect for this application.

$4.97? Here's my question:

How the heck can every one involved in the creation of that unit make any money?

From the raw materials for the fixture, the raw materials for the packaging , the shipping of those materials to the manufacturer(s), the inventory paper work at every level, the manufacture of the unit itself, the manufacture of the packaging, the printing of the instructions, the lawyers that wrote the disclaimers, the trucking of all of that stuff to various companies along t he way, the sales staff at the store, etc.

I don't know how many steps are involved or how many different entities touched the pieces and parts of that fixture, but it amazes me that everyone in the chain made money at a selling price of $4.97.

Sure, the easy answer is "volume" but the profit margin has to be fractions of pennies to everyone along the way. I know that it all "works" but it just amazes me when I look all the way back to the guy cutting down the tre e to make the box and the oil coming out of the ground to make the plastic an d everything else that has to happen between then and time the customer scans the item at the store.

It was made by some Asian person making a couple bucks a day.

That Asian person was just one small (and inexpensive) part of the end-to-e nd stream from the natural resource to the purchased product.

That goes from the scrap metal we sell them to packed in the box and loaded in a container in that same Asian country. At that point it is still a dollar part.

I'm still wondering how those Chinese on Ebay manage to sell things for $2, including free shipping to the USA. I just bought a USB hard drive interface that works with IDE or SATA for $3.75. I got two very long drill bits for $4. Those would have been $10 at HD, if they even had them. And there is a lot of stuff on there for just $2, maybe even $1.

But heh, Trump is going to rescue us from those horrors.

Part of this is the international postal union. Our post office has to carry Chinese goods at the rate they set. Basically our postal workers are also competing with the chinese nose to nose. When I sent some cameras to China my shipping cost was pretty much the price to get them to Long Beach so there is a flip side to that. China will dump a container of presorted mail on the dock and USPS carries from there pretty much for free.

Does Trump know about that?

Many outdoor wall-mounted fixtures have built-in light sensors. I have one on the front of our house between our 2 separate single family width garag e doors. I have a second one that only comes on if it senses a person afte r dark. So, both are fully powered at all times (unless the circuit breake r or GFCI trips).

Having a switch will just cause confusion.

The $4.97 fixture he plans on using does not have a sensor. That's OK. He c an get one when the $4.97 fixture fails in a few months.
