FAQ

We recommend being very careful by doing this. First and foremost there is some necessary technical expertise required to fit the bulb correctly into the chassis. Furthermore, there’s also a high risk of explosion with these kinds of methods with considerable irreparable damage to your projector. You always have to keep in mind that these bulbs contain a mercury gas and that they reach operating temperatures from about 1200°C. This is obviously not without any risk and therefore all manufacturers maintain a high level of quality during the production process. The level of quality that is maintained during this process is written down in a manual that is followed rigorous by all seven manufacturers of original projector lamps. Only when the lamp is produced in a spotless environment with all safety procedures followed, the highest level of safety can be guaranteed. If you start doing this yourself, you can easily miss some essential steps with disastrous consequences.  

This is way we also want to point out the fact that when you use a non-original lamp and your projector breaks down due to the usage of this particular lamp, any form of guaranty irrevocable expires. Therefore we cannot emphasize enough the importance of using original lamps for your projector. 

Because the smooth running of your projectors depends on the quality of the projector lamp and most of all because the use of non-original projector lamps poses health and safety hazards, we strongly recommend our customers to use and buy original projector lamp(s). 

Because we really embrace this philosophy we provided some additional information regarding this subject. You can find it on our website at the following pages:

• Why use original projector lamps?
• Buyers and consumers guide.

Also Philips, the inventor of Ultra High Pressure Lamps (UHP) and therefore market leader in production of original projector lamps, provides an online leaflet with some very interesting information.

• Philips: Make sure it's an original.

There are some simple rules to follow on how to extend the lifespan of a projector lamp?

• Never touch the projector lamp glass with bare hands, always use a towel, gloves or something similar.
• Shutting down the projector in a correct way
  • Please turn off the projector using the remote. never by pulling the cord from the power outlet whenever the projector is still working! After shutting down to standby mode using the remote control, the projector goes into a cooling mode. We strongly recommend to respect this cooling down and to wait 15 minutes before replacing the lamp.The fans run at a higher pace in order to cool down the projector lamp in controlled manner. A projector lamp achieves very high temperatures while working. If you interrupt power to the projector before the cooling is completed, the lamp cools down unevenly so that cracks can occur and the lifespan of the projector lamp can be greatly reduced.
• Shocks and vibration
  • Projector lamps are susceptible to mechanical shocks. Please note that a hot lamp is very fragile. Make sure that the projector is turned off and that the cooling down is respected.
• Economy Mode
  • If your projector is equipped with a 'high/low'- or 'economy'- mode, the average lifespan of a projector lamp significantly lengthen, by using this mode.

In 99% of the cases it's time to replace your projector lamp. For original projector lamps (metal halide lamps) you will notice that the brightness of the image fades as the lamp loses power. Some projectors use a built-in menu system to keep a close watch to the lamp's burning hours.

If you want to have more information on this topic or you want to know if your projector has this function, we advize you to have a look at your manual.

How often are the filters being cleaned? When was the last time the filters have been cleaned? How do the filters look at this moment? A speck of dust on the internal LCD-panels or filters can also cause spots on the image.

If you are unsure or you suspect that the problem can be found somewhere else, we recommend you to contact our service department for further professional assistance. You can reach us by calling 0032 3 457 85 10 (Belgium) or 0031 786 822 043 (The Netherlands).

When purchasing a new and original projector lamp you probably have noticed that each provider of projector lamps refers to a specific number of hours (ranging from 1500 hours to even 6000 hours). We would like to point out that this number is merely an indicative lifespan of a projector lamp. At present there's no such equipment that can indicate the lifespan of a projectorlamp in advance with any form of certainty.

You can almost compare it to the headlights of a car. Although the identical lights are plugged in at the same time by the manufacturer, how many times the lights went down at the exact same time? Indeed, never. That's why we always refer to an indicative lifespan of a projector lamp - or lamps in general.

Furthermore it's not just the projector lamp or its manufacturer that are solely responsible for an early failure. Also poor maintenance or bad usage of the projector may result in a shortened projector lamp life. If you're unaware of the dangers involved in this, we strongly recommend you to have a look at our online video tutorial 'how to replace a projector lamp'. This video tutorial will help you to ensure that you've installed the projector lamp in a proper and correct way.

If you still want to test the lamp, before you start, be sure to keep the following rules into account:

• Customized ballasts are used in projector lamps. During the ignition phase they are responsible for igniting the lamp by charging it with high voltage. As soon as the circuit is created, the tension is reduced to a lower operating voltage.
• Projector lamps can not be tested with an ampère or an ohm-meter. The operating principle of projector lamps is based on ignition of mercury vapor under very high pressure in a discharge tube. At the spot where the mercury vapor can be found there's no material that conducts electricity.

The amount of light during the projection determines the quality of the image on the screen. This fact plays an important role in choosing the right projector. The amount of light is measured in ANSI Lumens. ANSI stands for American National Standard Institute. This institute, where a large number of projector manufacturers are connected to, has the Lumen as a standarized measurement.

There is an average determined by the amount of light on various locations in the projection screen. This measurement is made at a one hundred percent white signal and is widely accepted by most manufacturers and therefore used. The higher the number of ANSI Lumens, the brighter the image.

ANSI Lumen high value benefits:

• Clear and bright images, even in a light(ed) environment
• Correct perception of all colors

and also this:

If you are looking for to watch a movie or play some games during daytime, well, it's best to choose a projector with a high ANSI Lumen value.

UHP (Ultra High Performance) is a metal halide lamp manufactured by Philips trademark with a lower wattage for equivalent brightness. The advantages of this technology are the following:

• a smaller and lighter projector because the power ballast is smaller and lighter
• a projector with a cooler, quieter and less expensive operation because of the lower wattage
• Longer projector lamp life due to lower loads on the projector lamp (wattage, temperature)

If the projectorlamp fails or stops working through what looks like a production error, please contact us for the return of the projector lamp. Do you believe that the cause is a technical failure, please feel free to contact us by mail (techninfo@cesbenelux.com) or by phone 0032 3 457 85 10 (Belgium) or 0031 786 822 046 (The Netherlands).

To qualify for a projector lamp warranty claim, you must meet following requirements:

• The serial number of the device (preferably a photo of the serial number)
• A copy of the sales invoice to the customer
• Photo of the total projector time (hold power button for 45 seconds)
• The defective lamp.

Then we discuss the error, in consultation with our service engineers and forward the claim to our European headquarters. After we've received

The main difference between a halogen and a metal halide lamp is the lifespan. A halogen lamp has a lifespan of about 700 hours. Metal halide lamps last approximately 1000 to 2000 hours.

Halogen lamps are usually cheaper (€ 35 - € 115) than metal halide lamps (€ 300 - € 600). The type of projector lamp you will need for a replacement is determined by the manufacturer. Halogen lamps will give you a yellowish image and metal halide lamps have a brighter, white image. Halogen lamps provide the same brightness throughout their lifetime. The brightness of metal halide lamps decreases depending on the course of life.

Due to the fact we work very closely with mainly all of the major original lamp manufacturers, we can guarantee that 95% of the lamps are on stock by an efficient inventory management. This allows us to deliver the original projector lamps within 24 hours, when ordered before 13h00, and otherwise 48 hours. We appreciate it very much if you keep this in mind.

The delay of delivery is also determined by the payment method. If you decide to pay it forward or pro forma, you will have to wait untill the money is fully transferred to our bank account. The time that goes over this depends from bank to bank.

The standard warranty is 3 months or 90 days with a maximum of 300 burning hours. There are exceptions for certain types of projectors, but they have to be purchased through an authorized distributor in the Benelux.

A summary of the warranties of the most common Sanyo projector types can be found here.

The projector lamp is the most important part of each projector. The lamp shines through an LCD or DLP system, making sure beautiful images are being realized.

You will find the lamp behind a square or rectangular cover on the outside of the projector. This cover is usually located at the bottom of the projector, but several types are located on the top or on the side.

The cover is usually fixed with two screws. If you unscrew these and remove the lid, you'll see the underside of the plastic casing which holds the projector lamp in place in the projector.

There is usually a handle on the plastic housing. Gently pull the handle to get the lamp and its housing out of the projector.
