Why? It’s XGA, 3,500 lumens and LED. You get 20,000 hours from the light source. The projector is wireless, PC-free and supports the iPad and iPhone.
Which markets is this projector best for? Conference rooms, classrooms, churches, restaurants, trade shows … It’s a great fit for most applications! Give us a call at 1-888-248-0675 to learn more.
What else makes this projector special? It has both the VGA and HDMI inputs, it’s priced right for all the features it has, and did I mention 20,000 hour light source!!! It’s a steal of a deal, as I say.
LED is not a display technology. Instead it’s a reference to the light source used.
LED projectors have a significantly smaller footprint than those that use traditional projector lamps. Read on to find out if these projectors are right for you.
How do LED projectors work?
Instead of a bulb, these projectors have arrays of red, green, white and blue LEDs. “LED” stands for light-emitting-diode.
When an electrical signal passes through an LED, it creates subatomic particles that must shrink themselves to pass through the semiconductor. In the process of shrinking, the particles give off a photon, a particle of light.
This light then gets reflected off of a DLP chip or passed through an LCD chip.
Pros and cons of LED projectors
The biggest advantage of LED projectors is their lamp life. LEDs last at least 10 times longer than traditional projector lamps. Many LED projectors can run for 10,000 hours or more. Since the lamp lasts the life of the projector, you don’t have to worry about buying new lamps.
Because LEDs are small and operate at much lower temperatures, LED projectors are usually small, lightweight and portable.
No warm up or cool down time is needed. LED projectors are also much quieter than projectors that use traditional lamps.
The biggest disadvantage of LED projectors is their brightness. Most LED projectors currently produce only around 10 to 1,000 lumens.

Because they are usually low-lumen, LED projectors are best for areas with controlled lighting.
The DLP chip used in DLP projectors was invented in 1987 by Dr. Larry Hornbeck, a physicist at Texas Instruments.
Is Dr. Larry’s invention right for you? Read on to find out.
How do DLP projectors work?
Inside a DLP (digital light processing) projector is a DLP chip covered in millions of mirrors. These mirrors are tiny: less than a fifth the width of a human hair.
Each mirror represents a single pixel. They tilt back and forth, reflecting light as necessary to create a highly detailed grayscale image.
The light is directed through a spinning color wheel. The wheel synchronizes with the DLP chip to create the final projected image.
Pros and cons of DLP projectors
Because a mirror on a DLP’s microchip can be stopped from reflecting any light, DLP projectors traditionally provide much darker black levels than LCD projectors. They are especially popular among home theater enthusiasts.
DLP projectors provide a less pixelated image than very, very low price LCDs. They also tend to project a sharper looking image during fast motion scenes.
Dollar for dollar, DLP projectors are generally not as bright as their LCD counterparts.
Some DLP projectors produce “rainbows”, a colorful trail that follows a moving object across the screen. Many customers don’t notice these, while others are extremely sensitive. Call a projector expert to learn more about a specific model.

Since higher-end DLP projectors traditionally last longer than their LCD counterparts, they are great for art galleries, museums, restaurants, schools, emergency response centers and retail stores.
