Tips on Choosing a Projector

Tips on Choosing a Projector

Projector Warranties: Return to Base Warranty
This type of projector warranty is the most basic warranty as well as the most common. The way it works is if the data projector is not working, you have to pack it up and return it to the manufacturer. The manufacturer will repair the data projector and send it back to you. This is not the best warranty because you are without your data projector until they get it fixed and return it to you. The average repair time is 2 to 3 weeks. Plus, you could be looking at a longer wait because the repair parts might be on backorder. Projector warranties can be confusing and can vary greatly from one manufacturer to another.
Projector Zoom Lenses: Manual Zoom Lens
Most projectors have a zoom lens, allowing the adjustment of the image size without moving the DLP or LCD projector. A projector with a zoom factor of 1.2 xs will allow you to adjust the picture by only 20%. Look for a DLP or LCD projector with a higher zoom, as it will allow you to present an image that will match most any screen size.
Some zoom lenses are maneuvered manually. For these manual zoom lens projectors, you typically adjust the zoom above the lens.
Projector Warranties: Repair or Replace Warranty
For Further Study.....
Simply put, if your LCD projector is not working, an audio-visual technician will try to offer a solution or repair the projector over the phone. Once the audio-visual technician determines what needs to be done, the technician will come to your business to fix it. If the technician cannot fix the LCD projector, the manufacturer will replace the projector with a new one.
Projector Warranties: Projector Lamp Warranty
Lamp warranties range from 30 days to 6 months. If you are putting your digital projector into a rigorous environment, it may be worthwhile to find a projector with a better projector lamp warranty. Also, the some new inexpensive projectors tend to have a very short lamp warranty, as well as repair warranty. Look at this carefully when choosing a digital projector, because the immediate savings may result in a hefty repair cost down the road.
Projector Warranties: Swap out Warranty
This warranty is the best type of projector warranty, but not the most common. If your digital projector is in need of repair, a technician will first determine the problem over the phone. Next, you can send the digital projector to the manufacturer to fix and at the same time, they will send to you a loaner projector to use while yours is being repaired. You usually receive the loaner projector the next business day. The loaner projector is typically a used projector, but it will work well until you get your projector repaired. Obviously, once you get your original digital projector back from the manufacturer, you are responsible for returning the loaner projector.
Disadvantages to Wireless Projectors
With the advantages that wireless projectors offers, there are a few disadvantages as well.
1. With wireless projection, there will be a slight delay when you give the projector a signal.
2. You cannot project full motion video in real time when projecting wirelessly.
3. The wireless projector will cost a little more than an equivalent projector that is equipped with standard cabling.
4. There are possible security issues with wireless projecting.
Projector Warranties: Dead on Arrival Warranty
Several projector manufacturers offer a projector warranty protecting you if you plug in your new multimedia projector and it does not work. This situation is rare, but it does occasionally happen. With the Dead on Arrival Projector Warranty, you simply return the non-working projector and the manufacturer will rush another new model multimedia projector to you.
Projector Zoom Lenses: Digital Zoom Lens
Most projectors have a zoom lens, allowing the adjustment of the image size without moving the DLP or LCD projector. A projector with a zoom factor of 1.2 xs will allow you to adjust the picture by only 20%. Look for a DLP or LCD projector with a higher zoom, as it will allow you to present an image that will match most any screen size.
A digital zoom lens on a projector allows you to further move into the frame by having the DLP or LCD projector continually resize the image. It is a nice feature to have in conjunction with manual/power zoom because as you move into the frame, the screen size remains the same.
Advantages of Wireless Projectors
Wireless projectors are becoming more widely available as more people are using wireless in their laptop computers and other technology. The main benefits of projecting wirelessly is as follows:
1. Cabling issues are eliminated which makes your workspace tidier, less confusing, and signal loss through cabling is no longer a problem.
2. Another advantage of projecting wirelessly is that you can switch between multiple PC servers easier.
3. Another advantage of wireless projectors is that the presenter will also be able to have better mobility while presenting without walking around or tripping over wires.
Which wireless projectors are the best for your application?

Lightings : Kitchen Lighting

Lightings : Kitchen Lighting

Accent Lighting - Accent lighting adds drama to a kitchen by creating visual interest. As part of the decorating scheme, accent lighting is used to spotlight paintings, houseplants, sculpture, and other prized possessions, or to highlight drapery or the texture of a wall.

Accent Lighting - House plants can be accented by aiming an up-light at the wall behind the plant, creating a dramatic silhouette of the plant against the wall.

Color - Think about the importance of color in your kitchen using proper lighting to bring out that dramatic color.

Dimming Systems - Today's dimming systems enable you to several things: lower light levels to conserve energy and increase bulb life, vary the mood of a kitchen, and alter the intensity of the light to suit the activity.

Down-lights - When down-lights are used in the kitchen they should be centered over the exposed countertop. This is another way of providing lighting that will eliminate someone working in their shadows on the countertop. Also, if white trims with white baffles are selected, the down-light becomes less obtrusive, blends into the ceiling a little more, and helps to prevent the ceiling looking like "Swiss cheese".

Fluorescent Lamps - When selecting fluorescent lamps for the kitchen try to select T8 lamps with a color rendering index of at least 85 and a color temperature of 3000K. This lamp is usually identified using the number, "830" or "930", somewhere in its product code.

Fluorescent Lighting - Fluorescent lighting is, without question, the coolest of all of the light sources and modern, high quality fluorescent lamps provide excellent lighting with very good color rendition.

Fluorescent Lighting - When selecting fluorescent fixtures for the kitchen try to select those that have instant start T8 electronic ballasts. This will ensure that the fluorescent lamp will turn on without flickering, that the fixture will not give off with much heat, that the ballast will not emit an annoying humming sound, and that the fixture will accommodate the new energy-efficient T8 fluorescent lamps.

General - Lighting can add depth and/or excitement to a kitchen. Let's face it, the kitchen is where you and your family will spend a lot of time so take the time to light it well so that it becomes an inviting and pleasant space to be in.

General Lighting - General lighting provides an area with overall illumination. Also known as ambient lighting, general lighting radiates a comfortable level of brightness, enabling one to see and walk about safely.

Indirect Lighting - Coves, soffits, and other concealed locations can also be used to provide very pleasant, very effective indirect lighting using T5 or T8 fluorescent strip fixtures.

Layers of Light - There are three basic types of lighting that work together to light a kitchen: general lighting, task lighting, and accent lighting. A good lighting plan combines all three types to light an area, according to function and style.

Line Voltage Halogen Lighting - Line voltage halogen lighting is often too hot to use in or under cabinets.

Low Voltage Halogen Lighting - Low-voltage halogen lighting offers a very white, crisp kind of light source that has excellent color rendering capabilities and often makes crystal and good china "sparkle".

Pendants - In general, pendants should be hung about 30" above the tabletop and be about 12" narrower that the table on all sides.

Task Lighting - Task lighting helps you perform specific tasks such a preparing food, reading, sewing, cooking, homework, hobbies, games, or balancing your checkbook.

Under Cabinet Lighting - Under cabinet lighting should be mounted closer to the cabinet front - not near the back of the cabinet. In the kitchen especially this helps to eliminate the possibility of your working in your own shadows.

Wall Grazing - Wall grazing provides dramatic illumination that reveals the texture of special materials, such as the brick and stone used in fireplaces. Wall grazing is uneven, brighter and scalloped at the top of the wall. For the most exciting effects, use PAR lamps in small aperture down-lights. Locate the down-lights no more than 12" from the wall and the same distance apart. Wall grazing also lights polished surfaces, such as marble without distracting reflections in the surface.

Wall Washing - Wall washers are special down-lights that direct light up to the top of the wall. They eliminate the shadows, sometimes called "scallops", which are characteristic of simple down-lights. Do not space wall washers more than 36" apart. For the smoothest effect, space wall washers 24" from the wall and 24" apart. Avoid locating wall washers near doors where they can glare into the eyes of people entering the room.

Xenon Lighting - Xenon lighting is long-life incandescent lighting that can be dimmed, if need be. This type of lighting can be used for cabinet, bookcase, under-cabinet, or indirect cove lighting.
