Frequently asked questions when buying a projector

Have you decided to buy a projector? Whether you need it for business or education purposes, you should know which features you need to look for. Thus, here are some basic questions which will help you on your quest to find the right projector for your needs.

Should I Choose Lamp Or LED Light Source?

Nearly all projectors use a specially designed lamp which produces brightness to project an image. These lamp-based projectors provide higher brightness and are an obvious choice for people who need to deliver a presentation to large audiences or rooms with ambient light. These types of projectors also tend to have the most advanced features and are ideal for larger rooms and wherever high brightness is needed.

The small projectors such as the mini projector, the pico projector, pocket projector use solid state technology like LEDs. Even though this kind of technology has not reached the highest level of brightness yet, it offers good color quality. These devices which are known for their portability are also sought for due to their low power consumption. LED-based projectors generate less heat and don’t demand much maintenance. On top of that, they are environmentally friendly and do not use hazardous materials.

How Long Will My Projector’s Lamp Last?

Most projectors use HID lamps as a light source. Lamp life is measured in hours, and over time the brightness of the lamp deteriorates. Thus, when you buy a projector, it’s important to take into consideration the cost of the device as well as the cost of replacement bulbs.

LED-based projectors have an estimated lifetime of around 20.000 hours. This translates to use of the projector four hours every day for over thirteen years. The mini LED projector can last up to 20.000 or more hours, while the pocket projector and pico projector can last between 15.000 and 30.000 hours. It’s more cost effective to use this kind of technology since users with the traditional lamp-based projector would have to replace the lamp at least 4 times over 20.000 hours of usage, at a cost of over 1000 dollars, compared to the maintenance free LED lamp.


How Much Brightness Do I Need?

Brightness is measured in ANSI lumens. You will choose a brightness level depending on three factors: the image size, the brightness of the room and the content. For instance, if your aim is to project a large image to a large audience, you should pick a bright projector and dim the lights. On the other hand, if you need to project a detailed image, you will need to minimize the brightness of the room.

When you choose a projector, find a product that is most suitable for your desired activities which may range from business presentations, playing games or watching movies and videos filmed with various IP cameras, drones, or some similar gadget. Furthermore, the light in the room needs to be optimized to the brightness of the projector. For small groups, 700 to 1000 lumens should be enough, while classrooms and conference rooms need 2600 to 4000 lumens. Therefore, before you buy a projector, consider its use, the size of the room and the amount of light, and the screen size.

Which Connectivity Options Do I Need?

The latest projectors offer a myriad of input and output connectors. For instance, a projector with both HDMI and VGA ports allows you to connect to several video sources, including DVD, set-top boxes, Blu-ray players, camcorders, video game consoles, PCs etc. HDMI can support any uncompressed PC or TV video format such as standard, enhanced and high-definition video. Small projectors like the mini LED projector, the pico projector and pocket projector come with mini HDMI ports.
