Starting in 2019, high Lumen, discrete RGB LED light engines are finding their way into projectors. Producing the same quality light as a bulb requires high-power RGB LED or multi-channel laser light source, which still commands a premium.Īs the price of better LED and laser light sources comes down, lamps will eventually be phased out. This is why they are still utilized in many higher-end home theater projectors from companies like JVC and Sony. While lamps are less expensive than LED or laser light sources, they are still an excellent light source. ![]() For example, where the projector is only being used for an hour or two each day, the lamp's reduced initial hardware costs can make it a better value. Lamps could be the choice if the projector is not being heavily used. ![]() As we mentioned, lamp-based systems are less expensive but have the shortest life. So why would you recommend a lamp as a light source projector? It comes down to cost and light quality. Lamps have the shortest life span of all the lighting solutions available today and the simple act of turning the projector on and off diminishes the lamp's operating life. The downside is their effective brightness degrades from day one, which means a UHP projector will never be as bright as the first time you turn it on.Īlso, lamps generate a lot of heat and thus require cooling, which requires more space, increasing the projector's size, number of cooling fans, and the amount of noise. They provide similar brightness with lower energy consumption and the UHP lamps produce a lot of light and are more affordable. The UHP lamp, created by Philips, was designed to be a more efficient alternative to metal halide lamps. In this article, we're going to take you through the advantages and disadvantages of each technology as well as help you understand which light source could better complement the environment that the projector is going to be installed. Today's projectors produce light in three different ways – lamps, lasers, and LED. All of this is determined by the intended use of the projector. Obviously, there will be other considerations like screen size, black levels, shadow detail, and color accuracy to name a few. But to start with getting the brightest projector, for the budget, is a good place to start. So how many Lumens are right for your application? A good rule of thumb is if it's too bright you can turn it down, but you can't turn it up if it's not bright enough, at least not without sacrificing image size. The problem is there is no requirement for any manufacturer to use this specification. An ANSI Lumen rating uses an average of several brightness measurements taken across the face of the light source. There is a standard for determining a projector's brightness called ANSI Lumens. So how do you tell how bright a projector is? That can be a little complicated. Lumens is an industry standard term that basically describes how much light a projector can put on screen and in turn, how bright the images appear on the screen. You can find out how to avoid them below.Trying to determine what type of projector to use? The first thing you need to look at is the projector's Lumens.
