Projector Rental Question: What's a Lumen?By John Beagle |
|
Answer: The brightness of a projector is measured in Lumens
When Renting or buying an DLP or LCD Multimedia Projector you need to match the brightness of the projector to your audience and room size. Larger rooms and audiences require higher bulb strength brightness.
Projector bulb strength brightness is measured in ANSI lumens or lumens. You also need to take into account the primary use of the projector, full motion video vs. static data.
Projectors range from around 650 to 5000 lumens in brightness.
Note: A standard 100 watt incandescent light bulb emits approximately 1700 lumens.
Presentations where the lights are on are the most desirable, but require higher lumen bulbs because you can interact and demonstrate off-screen with your audience.
Another consideration is portability of the projector. Lower lumen units are the most portable. As a general rule, as you increase bulb strength brightness, you reduce portability. High lumen projectors are larger and weigh more than low lumen projectors.
Less than 1000 lumens
-good for low ambient light, presentations.
1000 -2000 lumens -These
are the most popular units being sold and rented today.
Very practical and will work with some ambient light.
3000 lumens -Much
Larger unit than the 1000 to 2000 lumen units. Good for audiences of less than a hundred with ambient light.
5000 lumens
- For audiences of 100 or more under brighter lights
6000+ lumens - For large events like conventions, conferences, classroom training and trade shows where thousands of people need to view a presentation at the same time.
