Laser projectors are an exciting new breed of projector that utilise a Laser to create the light rather than a traditional Lamp. Just like with a normal lamp projector they come in both DLP and LCD variants. The laser light tends to be brighter so is primarily used in large venue business projectors however there are also some new home entertainment projectors that use a laser light too.
As with the diagram below they still use a DLP chip or LCD panels. They still shine out through a lens. The major change is the traditional lamp has been replaced by a laser module. LED based projectors perform a similar role but are limited to the amount of brightness they can produce so are mostly used in smaller portable projectors. Laser projectors’ brightness is still measured in ANSI lumens at the screen so you can compare apples with apples. There is a common myth that a laser projector always equals brighter, but this is not the case. A projector with a higher lumen rating will be brighter than a projector with a lower lumen rating.
The resounding benefit of a laser projector is the life of the light source. Though lamps have made improvements boasting a 10,000 and even 15,000 hour lamp life, the numbers are only achievable on the darkest economic mode where you lose a lot of projector brightness. In many cases the actual lamp life, if you are using the projector on normal mode, is only up to 5,000 hours. Most Laser projectors offer a 20,000 hour life with some coming out with economic mode settings to extend this to 30,000 hours and beyond. This saves you money on lamps, downtime and, in tricky installations, hiring scaffolds or scissor lifts. Laser projectors tend to use less electricity than a lamp projector plus most are also Mercury free so much better for the environment.
Downsides of laser projection are very few. They still use most of the same 'tried and tested' components fitted to projectors over the decades with a laser light module replacing the typical lamp. Laser projectors can be larger than a typical lamp model so are mainly recommended for installations rather than for portable use. As laser projectors tend to be quite bright the bulk of them are primarily designed for business use, at time of writing laser projectors for home are very rare. A laser projector will cost more up front than most lamp models.
The term 'Laser' often makes people think of laser pointers and we all know you should never point them at someone's eyes. The Laser used in a Laser projector is perfectly safe though as the laser light passes through a diffuser wheel and complies with the Class 2 safety standard. There is no risk of eye damage unless the user were to intentionally stare directly into the projectors lens for an extended period (which would be bad for you even with a lamp projector). According to Christie, "high-powered laser projectors are no more dangerous than other lamp-based, high-brightness projection systems." Some projector models also come with the added safety feature that turns off the light if it is detected that someone is near the front of the lens.
The team at Just Projectors are constantly testing new releases to determine the best projectors available for the money. Below we list a range of Laser projectors we recommend you consider. As always if you have any queries feel free to get in contact with us.
