Higher Education Embraces Laser Projection

Projectors remain the best display option for the larger screens needed in college and university classrooms. But move over, lamp-projectors — with the introduction of Casio LampFree projectors that use lasers and LEDs as a light source instead of lamps, you can now get the same high brightness and vibrant colors without the need to ever change a lamp!

Yes, there are no lamps! In talks with educators, almost 80% of the complaints about projectors are about the lamps. Since lamp replacement is the single highest maintenance cost of traditional lamp projectors, with replacement lamps costing hundreds of dollars over the life of the projector, LampFree projectors will save your facility a lot of money and aggravation, because there is no need to ever purchase, stock or replace a projector lamp ever again.

Even better, laser/LED projectors have a lengthy operation lifetime of up to 20,000 hours and degrade at a much slower rate than lamps (and so maintain their brightness much longer). This means that, in a typical university environment, your LampFree projector should last more than 12 years, based on an average of seven hours of use a day and 220 school days a year — and that’s without ever having to change a lamp!

Breaking the 5,000-lumen-standard myth

The old standard was 5,000 lumens, WUXGA (full HD) resolution. With the older technology in lamp projectors, 5,000 lumens was needed, because the lamps degraded so quickly. This is not the case with LampFree projectors. A 4,000-lumen LampFree projector is going to stay near 4,000 lumens for the majority of its long 20,000-hour life, unlike traditional lamp projectors, where the lamps start to degrade immediately and can lose up to 50% brightness between 2,000 and 3,000 hours of use. If you do the math, that 5,000-lumen lamp projector will be projecting a brightness of close to 2,500 lumens after only a couple of years of use, while the new laser projectors are keeping your images bright and clear for well over 10 years. Casio’s 4,000-lumen LampFree projectors can provide the reliable high brightness needed for higher education’s large classrooms and most lecture halls for years and years with minimal maintenance.

Casio’s award-winning Superior XJ-S400UN LampFree® projector is a perfect fit for higher-education classrooms and lecture halls; it provides a high brightness of 4,000 lumens in WUXGA (1920×1200) for full HD resolution, with crisp images and vibrant colors. A 1.7x zoom lens allows for increased flexibility in installations too. And it gets better, as there are numerous benefits gained from using LampFree light source projection technology.

Casio LampFree projectors are also filter-free thanks to dust-resistant cabinet designs. The dust-resistant cabinets have separate blocks, with the primary light source unit blocked off and tightly shielded. This suppresses dust intrusion and improves dust resistance, ensuring worry-free performance, even in dusty environments. It also helps to maintain brightness during the long life of the projector, since dust is not reaching the optical system. By eliminating dust intrusion, there is no need for filters — and therefore no need for cleaning, stocking or replacing filters at your facilities.

One of the overlooked benefits is reduced power consumption. Electricity usage could be the biggest area of savings for larger schools that use projectors in every classroom. Lamp projectors consume a high amount of electricity and generate a lot of heat. LampFree projectors run cool and are much more efficient to operate. Casio LampFree projectors use up to 30% less electricity right out of the box and can save up to 50% in economy mode. Also, some models have an intelligent light control feature with a built-in light sensor that can detect the ambient light in your room and automatically adjust the projector to the optimum brightness level so that you only use full brightness and full power when you need it.

LampFree projectors aid sustainability efforts

If sustainability and going green are important to you, then Casio LampFree projectors will be a big help with your earth-friendly initiatives. With the electrical savings we already mentioned, there can be a significant reduction in your carbon dioxide footprint — and there is no mercury. Many people forget that lamp projectors still use mercury vapor lamps.

Mercury is a highly toxic element that is hazardous to human health and to the environment. Although the use of mercury in products has been reduced worldwide, this hazardous substance continues to be employed as a light source for conventional projector lamps. By choosing a lamp-free projector, you are contributing to a mercury-free environment and eliminating a toxic substance from your facility.
So why are lamp projectors still on the market? Price. Sometimes it all comes down to budgets; a lamp projector’s purchase price is still cheaper than a lamp-free projector’s. But that can be a big budgeting mistake and wind up costing you much more in the long run. Even though the initial purchase price of a lamp projector is lower, when purchasing projectors you cannot only look at the initial purchase price. You need to look at the total cost of ownership.

The total cost of ownership includes all the costs that you will actually pay over the life of your projector. Total cost of ownership includes not only the purchase cost but also the cost of using your projector (e.g., energy, repair and maintenance costs). Lamp-free projectors consume less energy; they typically output up to 30% less electricity as compared to conventional lamp projectors. Lamp-free projectors require no expensive replacement lamps or filters, and since they require minimal maintenance, that means minimal labor costs. When you add up the original purchase price, the cost of replacement lamps, replacement filters, labor costs and higher energy usage, lamp-free projectors cost much less over their long 20,000-hour life.

In higher education, projectors and screens are still the most affordable technology when it comes to the large screens (100” and higher) students need to be able to read small text and numbers. Think about replacing old, costly lamp projectors with new 4,000-lumen LampFree projectors to provide the high-quality large images that larger classrooms need — and to reduce maintenance costs at the same time.

So, if you are interested in having no more lamps to replace, no more filters to replace, less downtime, lower electricity bills and lower maintenance costs, it’s time to switch to Casio LampFree projectors.
