Hi, we have a large Hitachi Ultravision TV. It's a regular TV - not an LCD or a Flat Screen. I has a great picture. Can anyone recommend what kind of ceiling lighting we should put in to minimize or eliminate the screen reflections? ANY ideas will be greatly appreciated! Thanks, Linda

Almost any ceiling lights which are directional will do pretty well. If you get general lighting, such as lamps, you have a big visible reflection. But, recessed lights, track lights, pendant lights (directional) etc. can all give you light where you want it, without producing reflections which you don't want.

But, it's also about angles - if you can see where the light itself is in the reflection of the TV, then you will have a more difficult time avoiding that reflection.

AV_Integrated makes the good point that the surest way to avoid visible reflections in the shiny screen from ceiling lights is to locate the lights in the right places on the ceiling. These places can be calculated pretty easily provided the room isn't very wide.

Figure where the closest audience will sit and draw a line from their eye to the upper edge of the screen. Extend that line until it hits the the plane of the ceiling. If it hits the wall behind the TV before it hits the ceiling, keep extending it through the wall until it reaches the plane of the ceiling. When you've found that point measure how far behind the front of the TV it is. Call this distance D. Now measure how far behind the front of the TV the wall is. Call this distance E. Conclusion: the ceiling lights should be located within D+E of the wall behind the TV.

In other words, the no-reflection condition requires that the ceiling lights all be located at the same end of the room as the TV is. Unfortunately, putting ceiling lights there is maximally distracting to the TV viewers.

If the room is very wide the lights can be farther than D+E from the wall behind the TV provided they are way to the left or to the right. The geometry is a little messy for this case.

actually it may depends on many things, the space of your room, you home furnitures and many other aspects .may be you can get some idea here:
In hall, lobby, passageway, living room, small-sized spherical lamp, oblate and square ceiling-mounted luminaire can be your choice and make sure their sizes are fitting for the space. Sometimes there can be spotlight up in the entrance place. Lamps for hall, passageway and other rooms shall have different importance on primary and secondary.
Drawing room can be divided into two kinds: large-scale drawing room and drawing room for household. For large-scale drawing room, we recommend mixed-up decoration and general illumination together with local illumination for household drawing room. Such as wall lamp, spot lamp and flush light lamp can be used as local illumination, ceiling lamp and ceiling-mounted luminaire can used as general illumination.
The main function of bedroom is rest, not just sleeping. Many families also make up and store clothes in it. Lamplight shall be mild and graceful. Diffusion may be optimal.
The color of the lamp is most important for dining room. Any improper color may change the color of dishes. Warm color is widespread and avoid cold one.

Direct illumination or vertical illumination is perfect for reading room. Radiating from your left hand and in front of you is both OK. You can select a desk lamp with arm coming back or with a switch to adjust light.
