Can these bulbs be used in lamps where the bulb base is on top? In other words the lamp is upside down or shining down instead of up?

I have mine installed on the patio fans which is also upside down. As long as the bulbs do not exceed the wattage rating listed on the lamp you should be ok. Also I ordered the 60W bulbs, but recieved 45W, just something to watch for.

I don't see why not. In our application (ceiling fan), they are installed in a horizontal position.

Yes. I used them in a hallway sconce with opposing bases. The upside down base tended to burn out first but otherwise fine.

I have 2 lamps like you described in my entry hall. They came with these bulb (which I love by the way), they are on quite a bit being in the entry and I have had no problems. Have had about 9 months. I don't believe the lights I have are made any different than others.

Yes - the bulbs can be upside down in the lamp without a problem. The lamps we have them in our sideways.

Yes. I have two mounted in the same exact type of fixtures and they work excellent. In fact, in my opinion, they work better upside down than in a conventional lamp due to the design of the bulb. The lower part has no light output so there are "dark" areas that you can clearly see through a lamp shade.

The bulb is lamp specific.They can only be used in a lamp that requires tht model bulb.

No they are not, these bulbs have the big base size, the same as a regular bulb.

I am not entirely sure what you mean I don't think your question is entirely clear. But these are A19 base bulbs which is a pretty standard light bulb base in the US. If you look at a lamp in your home it likely is a A19.

No, you will have to get the bulbs with a different base, the one's u purchased have a regular lightbulb base, you need the candelabra base for that application. Good luck

None that I am aware of at present. I installed my Full Spectrum Light Bulbs (ALZO 45W CFL) in light sockets without a globe or shade (not my original plan). Used in this fashion they throw a lot of light as long as you aren't too concerned about appearances.One is mounted horizontally and another vertically. Both have been in service since the beginning of this year without any problem.

I guess. The contractor installed for us. But I see no reason why it can't be upside down. Our bulbs are facing the floor actually.

inside there is a glass bottle upside down, that threads to the bottom of the lamp. Think about a glass jar with a round bottom to cover the light bulb.You can use any light bulb up to 60 watts I think. I use the spiral daylight 13 watts and they look great.You can use any regular light bulb up to 60 watts I think.

The shades screw into the base so I think it should work fine. The only thing to be aware of us that the shades are open at the end so depending on the hight of them you might be looking at bulb

I suppose you could just install them upside down. Doesn't seem like a good solution to what you're trying to accomplish though. They make fixtures designed to light stairways safely and properly.

We used normal bulbs. From my research that is what is required. Bulbs are mounted on downward position and on a slight angle

I used the bulb in the upright position but I don't believe it would be a problem to install the bulb upside down.

I use them in fan lights base up without problems, to my knowledge. I also use them in outdoor fixtures with base down.

They are keyed so if it is opposite there is nothing you can do. Not unless you can rotate the keyed entry on the headlamp which I doubt. Alternatively, just keep them in high beam =D.

this bulb was purchased as a replacement for a Happy Light. It does not have the standard screw in base therefore it would not work in standard lamps.

I believe these bulbs need to be in an open fixture...They can be placed in a dome fixture if it's not full enclosed.
