ViewSonic Corp., a global provider of visual solutions, has been dedicated to developing its Luminous Superior (LS) series of lamp-free projectors that provide high brightness with more benefits than traditional lamps. These include better energy efficiency, extended lifespan, and eco-friendliness, making lamp-free projectors an accessible solution for businesses looking to enhance their sustainability efforts and meet Environmental, Social, and Governance (ESG) requirements.

“ESG has become an increasingly critical issue, necessitating the involvement of governments, enterprises, and all individuals. ViewSonic also takes it seriously by following our commitment – foster a sustainable future – throughout strategic operations and product development,” said in a press release by Dean Tsai, General Manager of Projector & LED Display Business Unit at ViewSonic. “We have set a five-year goal to accelerate global progress towards a carbon-neutral society by proactively increasing the proportion of lamp-free products to 70 percent and reducing the production of lamp-based products to around 30 percent.”

The ViewSonic LS Series Paving the Way to a Greener Future 

The LS series aligns with the SDG12 (Sustainable Development Goals) to “ensure sustainable consumption and production patterns” from the United Nations – especially encouraging energy-efficient light source adoption.

Powered by the latest laser and LED technology, the LS series offers a wide range of brightness levels, from 2,000 to 6,000 ANSI Lumens, resulting in bright images with reduced power consumption. These lamp-free projectors minimize their carbon footprint and mitigate the drawbacks associated with lamp-based projectors, such as toxic mercury, frequent bulb replacements, and high maintenance costs. Moreover, LED and laser light sources operate without the need for warm-up or cool-down periods. This enables lamp-free projectors to be instantly powered on and off, significantly enhancing operational efficiency. Additionally, ViewSonic’s latest lamp-free projectors are more compact and lightweight, making them more flexible and easier to install.

The benefits are demonstrated through ViewSonic’s 210W laser-based projector, the LS740HD. Rated at the same 5,000 ANSI Lumens as the PG800HD, the LS740HD consumes 40 percent less power over 20,000 hours of use, resulting in CO2 emissions savings equivalent to those produced by burning 171 gallons of gasoline. Furthermore, with the average electricity rate at $0.15 per kWh in the US, a company can save $480 on its electricity bill with each of these models.

In line with sustainability practices, lamp-free projectors boast an extended lifespan that surpasses that of lamp-based projectors. To illustrate, a lamp-based projector would need an additional 11 light bulbs to match the 60,000-hour lifespan of a single LED light source. Businesses gain significant advantages from opting for lamp-free projectors—not only in fulfilling their ESG commitments but also in reducing the total cost of ownership due to the extended lifespan of the light source. Furthermore, general consumers won’t be exposed to toxic mercury in light bulbs or face costly lamp replacements, thus simplifying maintenance.
