Do these bulbs have an orientation issue? Ex. Screwed into a table lamp (threads down) or a celling fixture (threads up).

Yes, all LED bulbs are sensitive to orientation. If mounted in a ceiling fixture (especially a fully inclosed one), the expected lifetime will be reduced. However, Cree bulbs theoretically have well-designed thermal management, so if you're choosing an LED light to install in a ceiling fixture, this is the one I'd go with.

Standard Threads, They screw in the same as any normal bulb, that in another attribute of the Cree bulb, their traditional approach as apposed to the ballast base type bulbs. Plus there is no difference between threads up or threads down.

These are a very normal looking bulbs both when on and off. Orientation, housing design, and bulb visibility should not be an issue. Other bulbs like the Philips Slim Style LED bulbs are flat and just look weird when the bulb is visible, or the orientation of the fixture threads aren't just perfect. (You don't want to see that slim bulb from the side in your vanity fixture!)

Peter, I've used these bulbs with threads up, down and sideways and have noticed no difference in performance. I have never encountered an LED with orientation sensitivity.

Not as they are manufactured. You'll probably have to shave down the plastic tabs on the lamp housing.

The angle reflected from these bulbs are straight on, guess that's may reflect in a 4-45 degree angle....They are very bright...IMO! Hope this helps.

My lamps work for the 3 way lighting. I used the bulbs as specified and they work. Your bulb or lamp may be damaged. If the lamps are, try exchanging.

If you are talking about the one at the left, the answer is "No." The bulbs I purchased are in a spiral.

The screws that hold the light bulbs are already on the fixtures. You have to unscrew them to put the light bulbs in.

Hi. First of all I think I had the lamp shade upside down. The light bulb was showing. My husband turned the lamp shade over and the light bulb doesn 't shoe but now the lampshade wobbles. I have to take time to figure it out. I love the lamp but it 's just not right

These can be mounted vertically (as I have a pair) or horizontally. May require removal of screws to position the mounting base properly. The screws that Danusia complains about will be oriented at the top and bottom edges (it sounds like she got a returned/repacked fixture - the glue would have been the sticker residue). You may consider the incandescent version (http://www.amazon.com/gp/product/B002VB5696) with halogen bulbs. I am using 40-watters that throw more light than standard 60-watt T10s. CFLs aren't really suited for the short on/off cycles in a bath.

The light will spin on is post almost completely 360 degrees. Referring to the picture, the light is at it's midpoint of tilt. Using the the bulbs axis as reference, the light will move from parallel to completely perpendicular to the base.

This adapter connot be pointed straight down...perhaps a bit in excess of 45 degrees for both lights to be pointed in the same direction. One light could be pointed straight down if you were to keep trying different screw-in orientations until you were able to get one socket to end up on the bottom...then that one could be pointed straight down and the other no more than straight ahead. To point them both straight down you would have to buy an additional swivel adapter to go between the socket and this adapter.

This has never happened to mine. Sounds like a bad light. I personally think they are great!

I have mine screwed into the wall. The lightbulb covers slide off and I believe the bulbs screw in.

They do but the wiring on this lamp is all screwy, have burnt out 4 bulbs in about a month. Not sure if I got a defective one or just need to take apart and put back together, the wiring does run through the poles.

Did you try putting the bulb in the other way? The bulbs are + and - and only work one way. If it doesnt work one way, then flip it around the other way.I hope this helps.

I had the same problem with all 3 I bought. Its a quality problem from the factory. I ended up having to scrap them and buy different fixtures from a different vendor and manufacturer.

If you find out let me know. Mine are all horizontal or pointing a bit down.

I noticed another brand allowed the bulb to be "re-clocked". I think I see that on mine, but in town I never get to go on high beam. I'll have to re-check the 3 tabs to see if I can rotate them up.
