First things first: gather the necessary tools. A screwdriver and a cloth.
Luckily, you’ll mostly only need a manual screwdriver to remove the panel. You will also want to have a soft, non-abrasive cloth handy to help avoid any contact with your fingers and the lamp assembly. A Micro-Fiber cloth is highly recommended, and widely available from most supermarkets.
Turn off TV or Projector. After the unit has cooled down properly, remove the power cord from the outlet and the unit completely.
Remove the bulp compartment door. The lamp compartment on projectors is usually located underneath the projector unit. Remove the screws and the lamp compartment door should lift off nicely.
Remove the lamp assembly. Be carefull and pull out the lamp assembly. Disconnect any power cords that may still be connected to the lamp assembly. Put the bulb to one side for recycling.
Clean the lamp compartment. Dust gets everywhere and while you have the projector open, use a soft cloth or micro-fiber cleaning cloth to remove any loose dust from the lamp compartment.
Insert the new lamp. Carefully re-connect power cables to the new lamp and slide the new lamp into the compartment in the same way that the original lamp came out.
Replace lamp compartment door. Set the lamp compartment door back into place and securely screw in the door without screwing it in too tightly.
Reset the lamp timer. Instructions on how to do this should be covered by the instruction manual. You’re Done! Enjoy your projector again and make sure you have a backup lamp handy in case the lights go out unexpectedly.
Projectors can provide functionality for every member of the family. They can even temporarily transform spaces of your home into something entirely different and create memorable moments for you, your family and friends.
Many people envision projectors as huge clunky grey boxes with a blurry picture and minimal functions, but todays projectors could not be farther from this. Projectors these days are sleek, small and extremely high quality pieces of technology that are used in almost all businesses to communicate globally with customers.
Projectors can help businesses reach potential and existing customers in a personal and professional way. This is essential with businesses looking to grow and interact with customers based abroad. It cuts out the need to send impersonal emails or phone calls. Faces can be put to names, and business can become more meaningful and intimate helping to grow relationships and trust.
Are Lumens Important? The short answer is yes.
In fact, lumens are pretty important. Whether you need a projector for your home, office or school, there are many factors that should be considered before purchasing a projector; one of the main factors being lumens.
Projector lumens will always be listed in the projector specs, and to put things simply, the more lumens a projector produces, the brighter the image will be. It also means that the days of making a classroom or office pitch black before starting a projector are long gone, as the projector should be bright enough to project a perfect image in daylight.
What are Lumens?
Lumens are a way to measure brightness from light sources, so the more lumens a projector has, the brighter the light is. To help you better understand, below are some rough examples of lumens in other light sources:
- Candles – 13 lumens
- Average sunset – 400 lumens
- Car headlight – 1000 lumens
- 100 watt light bulb – 1600 lumens
- Projectors – these range from 500 lumens to 10,000 lumens
Do Lumens Matter?
As you can probably tell by now, lumens are one of the most important factors you need to consider before purchasing a projector. The brighter the projector is, the less dark or ambient light will matter with regards to picture quality. It also means you can place the projector as far away from the projector screen as desired.
Here is a rough guide of what can work when you have to choose a projector for different spaces.
- To use a projector in a living room with the lights off, you would need approximately 1,500 lumens to 2,000 lumens.
- To use a projector in an office or a small classroom with dimmed lights, you would need approximately 3,000 lumens. If it’s in a hall or larger area, then a 5/6/7/8k lumens projector could be the best choice.
- A movie theatre would need massive 20,000 lumens.
If you are unsure of what projector and lumens to choose for your space, it’s a good idea to get a specialist in projector installations to do a thorough site survey to assess the space, perhaps measure it out and to discuss what you need to achieve from your projector. A specialist will look at the full layout, stress test the walls and ceilings and advise on what the best mount, be it wall or ceiling, is best for space.
How Lumens Can Decrease Over Time
For projectors, the light source is within the bulb of the lamp. The bulb is of key importance to the amount of brightness a projector produces, and over time the brightness of the bulb will slowly decline and a replacement bulb can be bought to give the projector its lease of life back.

Rear View Projection.
Rear projection is a special effect technique that is used in film productions. It is the effect of combining the foreground with an existing background that could be filmed beforehand or painted or computer generated images (CGI). It is commonly used in the film industry, mainly in driving scenes or to show some form of background motions. This effect is to create an illusion that the characters are in a place they are not in, very similar to a blue/green screen effect.
The actors would have to stand in front of a giant screen while a projector is positioned behind it to show an image for the necessary background. The background usually would appear much fainter than the foreground, and it could be a still image or a moving image, but they are both called the “plate” and one might also hear “Roll plate” in a film set where rear projection is used to instruct the crew to begin the projection.
In order for rear projection to work and not showing any faults in the plate, the sound stage camera has to be in perfect synchronization with the projector. Both the camera and the projector have to be operating at 24fps, so that there will be no fringes or any halos appearing in the screen.
The rear projection was mainly used to film actors in driving or any moving vehicle scenes, which is in fact a vehicle prop that is set up in front of the plate. In such cases, the actor would seem very odd compared to the projected background, because the projected background was not shot steadily and the bumping movement of the background was not recreated by the actors.
