Movie projectors have four main sections namely the spool assembly, the audio assembly, the lens assembly, and the lamp assembly.

• Spool Assembly – The Spool assembly aids in the movement of the film through the projector. It contains parts required for storing and moving the film. Platters, sprockets, and cambers are parts of the spool assembly.

• Audio Assembly- This assembly is the source for sound. Two types of technologies are involved in audio assembly, namely optical and magnetic. The optical system comes with a light source and a photocell and is the most common. On the other hand, the magnetic system comes with a recorder head that is directly in contact with the film.

• Lamp Assembly – The lamp assembly is one of the most important parts of movie projector equipment. It is the primary element of the light source and contains all the parts needed for the illumination of the image on the film. Xenon bulbs are commonly used in movie projectors as they work for thousands of hours with the same intensity. The best part is that even if the bulb dies with usage it can be replaced. In case you require a replacement projector lamp, BulbToGo.com would be an excellent place to go as they offer quality projector lamps at great prices.

• Lens Assembly – The light from the lamp assembly then passes through the picture head and lens assembly. Basically there are two types of lenses, namely flat and Cinemascope. Depending on the movie, the lens can be removed and changed in most movie projectors.

A video projector is an indispensable part of most businesses and presentations. Before investing in a projector, you should analyze all the features to get the best models available in the market. This video projector buyer’s guide will help you make an informed decision.

The first thing to consider before buying a video projector would be to think about the place where you intend to use the projector. For instance, if you’re planning to use the projector in a small, dark room, then it will suffice to use a projector with less lumen. Whereas, in a large hall, you can go for a projector with more light intensity to enjoy a brighter image.

A factor that complements brightness is the contrast ratio. A high contrast ratio helps avoid washed-out images. A contrast ratio of at least 1500:1 is recommended in order to experience whiter whites and blacker blacks.

Portability of the video projector is another factor that needs to be considered. The smaller and lighter the video projector, the easier you can move it around.

For the video projector to deliver excellent image clarity, a projector lamp is one of most important factors to be considered. The life of a projector lamp is typically a few thousand hours. Once the luminous intensity falls well below the initial capacity, and the images aren’t projected as remarkably, then it is an indication that it is time to go for a replacement projector lamp.

If your projector lamp needs to be replaced to return vivid clarity to your presentations, then choose from an expansive collection at BulbToGo.com. They carry high-quality replacement lamps at affordable prices.

Paper presentations have become passé. PowerPoint presentations incorporated with animation and sound effects have become the norm now. Projectors can be used for putting up presentations due to their excellent image quality they produce. One of the important parts of a projector is the projector lamp. It is impossible to give presentations without projector lamps as they are the main source of illumination.

When you choose a projector lamp that best suits your needs, it not only makes your work easy but also saves time. This projector buying guide will help you to choose the right kind of projector lamp.

It is necessary to consider the price and compatibility when buying projector lamps. The other features that should be taken into consideration while purchasing these lamps are its resolution and brightness.

The sharpness or clarity of the image displayed by a projector is determined by the resolution. The lowest resolution is SVGA (800 x 600) and the highest is UXGA (1600 x 1200.) Projector lamps with good resolution are best fit for presentations in large auditoriums or home theatres. On the other hand low resolution projector lamps will do for simple office presentations.

Projector lamps with higher lumen produce clear images and can be used for presentations in large office rooms or in outdoor areas. Projector lamps with low lumens are apt for indoor presentations.

It is always good to choose a projector lamp, which has the most number of options for connectivity. BulbToGo is the best online store where you can purchase good quality projector lamps and projector replacement lamps at reasonable costs.

Not everyone is aware of the science behind projector lamps. Though it is not mandatory to know about projector technology, it would help us to have a better understanding on how these projector bulbs work.

Technically, projector lamps are called high intensity discharge lamps because they produce light from a very small electrical discharge. Hence, they use less energy to give brighter light. It is very advantageous to use such projector lamps because they not only help conserve energy, but also work for a long period of time.

The lighting technology in projector bulbs is similar to the process by which lightning is produced in an electric storm. Nitrogen atoms present in the air glow as a result of the high voltage discharge created during an electric storm. This can be compared to the working of a projector lamp. Metal halide atoms present in the projector lamp glow due to the electrical discharge that is produced from the projector’s power source.

Mercury halide gas is used in projector lamps as it has a high vapor pressure. Halides are also used because they vaporize easily avoiding corrosion of the projector bulb.

Scientists discovered that when a metal is introduced to a naked flame, it glows. This basic concept of using metals to create high intensity light was applied to projector lamps. An electrical discharge is produced between the two electrodes used in the projector bulb. This discharge excites mercury atoms to produce light.

Though, these lamps may be costly at first, they are cost effective in the long run. If you are planning to buy projector lamps at affordable costs, BulbToGo is the perfect place to go to.

Projector lamps are characterized based on different types namely, manufacturer original replacement lamps, compatible lamps, and original alternative lamps.

Original Replacement Lamps

The projector replacement lamps produced by the original projector or the rear projection TV manufacturer are called original replacement lamps. These projector lamps are manufactured according to the same standards as that of the original projector or the rear projection TV. The manufacturers do not in any way compromise on the quality of the projector replacement lamps. These lamps are usually produced individually keeping in mind the specifications required by the original projector or the rear projection TV.

Original Alternative Lamps

Original alternative lamps are perfect replacements for manufacturer original replacement lamps. They are cost-effective compared to the original manufacturer replacement lamps. The original alternative projector lamps are manufactured in a high-quality environment and are usually upto the same standards as that of the original replacement lamps.

These replacement projector lamps are manufactured to ISO9001 standards, which ensure a good quality. Original alternative lamps are usually the result of extensive research and testing by several projector lamp experts. They are designed to give high performance levels at low costs.

Compatible Lamps

Compatible lamps are also known as copy lamps. These are usually imported from the grey market and are of unknown manufacturing standard. They also don’t come with any basic warranty. This is because compatible lamps are manufactured by non-regulated companies. They’re packaged in boxes without labels and the prices at which they’re offered are also too low.

So, it’s always better to go for original alternative lamps, if you can’t afford the original replacement lamps. To buy genuine projector replacement lamps or projector bulbs, BulbToGo.com is the ideal place.

If you are planning to purchase a projector lamp, then it is important to know all its components. A complete projector lamp module consists of a bare bulb, connector, and lamp housing. This post deals with a few facts about bare lamp components.

If we look at the construction of a bare lamp, we can find that the burner is placed inside a reflector. This burner is connected to a cage or plastic covering that surrounds the lamp, which is connected to the projector via connectors.

Burner, also known as high intensity discharge bulb, provides brighter light when compared to other types of bulb. This increased output of light obtained from a single high intensity discharge bulb is one of the reasons for such burners being used in bare lamps. A burner plays a major role in the quality of the picture delivered by the projector.

Reflector is one of the key components of a bare projector lamp. The reflector directs the light from the lamp towards the mirror. This mirrored panel prevents scattering of light and ensures that very less light is wasted.

The front glass in a bare projector lamp is another essential component. Hot bulbs are susceptible to quick damage and the front glass prevents physical contact with the bulb. It also avoids accumulation of dirt on top of these bare lamps.

Bare lamps can be bought from the market and replaced manually. Be it projector lamps or projector replacement lamps, BulbToGo is a great place to buy them.
