Lamp projectors tout more than 2000 ANSI lumens, while laser projectors offer more than 3500 with the option of further scaling by way of attachable modules. LED projectors, on the other hand, suffer in this regard, with a lumen count that only goes up to a maximum of 2000.
Laser projectors use LED lights to project their image. LED's are brighter, have a sharper image, require no heating up, and use less electricity. Running at a lower temperature means laser projectors don't require as much cooling inside the projector unit.
The Projector Lamp, otherwise known as the a projector bulb, is a replaceable part of the projector that needs to be maintained according to the lamp life of the projector, which averages between 1,000 and 2,000 hours. ... Projector lamps become quite an expense over time.
What are the disadvantages of LEDs?

LAMP PROJECTORS:
Lamp projectors are the traditional projectors you know (and love?). Lamp projectors use a giant light bulb to project their images on the screen. The lamp takes time to warm up, loses image brightness after 10 hours, and requires fans inside the projector to deal with all the heat generated.
However, lamp projectors are cheaper and easier to setup in the initial stages. Since lamp projector technology has been around for a number of years, they have become relatively cheap and easy to maintain.
Benefits:
Low initial investment
Low TCO even at similar total number of hours vs. laser
Full brightness with lamp replacement
Considerations:
Requires maintenance
Labor costs for lamp replacement
Potential downtime due to maintenance
LASER PROJECTORS:
Laser projectors use LED lights to project their image. LED’s are brighter, have a sharper image, require no heating up, and use less electricity. Running at a lower temperature means laser projectors don’t require as much cooling inside the projector unit.
Laser projectors also have greater contrast than lamp projectors. Blacks on laser projectors are much stronger as the LEDs just don’t fire on black sections of the screen. Lamp projectors need to project no matter what, meaning blacks are never as dark as they could be.
Laser projectors also last longer than lamps. The unit in most laser projectors can last for 20,000 hours, meaning they could be run for 8 hours a day for 12.5 years without maintenance.
Laser projectors do cost more. The laser projection units cost more as well due to the newer technology. However, when you balance the figures, the electricity and maintenance savings of a laser projector over its lifetime compared to a lamp projector makes the benefits obvious.
Benefits:
Virtually maintenance-free operation
Instant power On/Off
Absolute Black- higher contrast ratio
Considerations:
Higher initial investment
Constant brightness reduction
Costly light engine replacement
