UHZ66
Eco-friendly compact high brightness 4K UHD laser projector
The UHZ66 is one of Optoma's most compact and hassle-free 4K UHD DuraCore laser projectors to date. Designed for maintenance-free continuous operation, this this 4000-lumen projector delivers powerful image performance with flexible installation features and extensive connectivity options in a sleek, compact form factor, up to 34% smaller than previous Optoma models.
To support Optoma’s commitment to sustainability, the UHZ66 cuts power consumption by up to 45% compared to Optoma’s lamp-based projectors. Energy-saving DuraCore laser technology ensures a long product lifespan of up to 30,000 hours without the need for additional lamps, requires minimal maintenance, and is mercury-free, further lowering its carbon footprint.
An added benefit, the UHZ66 features an external power supply offering more reliability, portability and energy efficiency.
Designed with the environment in mind, the eco-friendly chassis design is made with up to 50% PCR (Post-Consumer Recycled) plastics and the packaging contains up to 97% recyclable materials. In addition, the compact product and packaging size of the Optoma UHZ66 projector allows 2x more products carried per container, resulting in more efficient logistics to help further reduce carbon emissions.
The UHZ66 offers superior contrast, accurate true-to-life colour reproduction for movie lovers and delivers bright 4000 lumens so sports fans can enjoy live action with the lights on. It also reduces input lag down to as little as 4.4ms (1080p 240Hz) – perfect for a competitive gaming advantage.
