There is always some fine print. I don't know if this is the light that you purchased, but it has the exact wording, so I'll show it as the example. The line in question means that they are surface mountable up to that level of light output (since they produce more heat.)

High output fluorescent lights do generate a fair amount of heat. If directly attached to a solid surface the ballast will over heat and may turn off to cool down. The life of the light will be reduced due to the high heat. I always use 12 gauge single jack chain for mounting the 6 tube enclosed fixtures. I do have 5 or 6, 4 tube open fixtures that are ...

There's no reason that you can't fasten crown molding to ceiling joists... except that they'll probably only be present along half your walls. Unless you happen to have a hip roof design, the other half will run parallel to the joists and you probably won't have backing. In that case, trim screws with hollow-wall anchors may work, or nails backed up with ...

What I ended up doing was putting up batons on the ceiling and plasterboard over the top. We did this with the other wall which was questionable too. Benefits here are that the finish is much better once finished, and it's decidedly less plastering than doing the entire wall. The cost was likely higher than if we had plastered, but the end result was much ...

That's an extremely long span for 2x8s, even tripled. Do you know whether there was ever an intermediate post? Most would suggest that you have a engineer look over your situation. Existing framing isn't always a good indicator of what to use. At any rate, a pair of 1-3/4" microlam (or laminated veneer lumber--LVL) beams will almost certainly suffice. The ...

2x8's should do the trick if possible tho double two up in the middle with a piece of plywood sandwiched inbetween for an expansion joint

The local IRC book would be handy for you. I have a few screen shots that may help, but only as a guide line. A building inspector will have the final say, but this is what they go by. This does depend on where you live, for it has to do with snow loads. Roof cover factors in a bit too. Span does not matter if it is 4/12 pitch or a 12/12 pitch. The span ...

Would adding a ceiling keep my garage at a Warmer temperature for longer? Yes, but you probably need to at least seal around the doors and perhaps insulate plain metal doors. what is a good and low cost material to use? In my part of the world, mineral wool in rolls. You can suspend this in netting (the upper floor of an office building I use ...

Low sloped roofs are problematic only when they get wet! (the water doesn't shed fast enough). What the roof contractor probably meant regarding flashing the valley was (I'm guessing) is if you re-roof it would install under the new shingles. Here is an easier and more successful suggestion which I have used with great results. If you'd rather defer a new ...

Yes, you should install covers on the boxes. You should be able to pick up covers at the local hardware or big box, fairly cheap. Just make sure you measure all the boxes, and note their shape, before heading to the store. If the mounting screws are not in the boxes, you'll also have to pick up some of those. National Electrical Code 2014 Chapter ...

I have seen this done. There is no special trim. Steps: Install trim Take a utility knife and scribe around the trim exactly. take out enough drywall layer to set trim - some guys just take off the paper mud and sand where needed after reinstalling flush trim Does it look better? Debatable. Is it worth it? Almost in all cases no. Note: My opinion ...

One thing the trim does typically is hide the edge of the drywall which usually, one would not want to look at because it's rough and ugly. It's hard to imagine trim that doesn't extend (at least the thickness of the metal itself) below the surface of the ceiling. If you want a trimless look, what you will probably need to do is apply drywall compound up ...
