LampSave Mode

Projector lamp replacement costs make up the biggest part of the total cost of projector ownership. The LampSave Mode is designed to adjust the lamp power dynamically by content brightness level to extend projector lamp life significantly by 50%! The lamp replacement frequency is also reduced by up to 50% to lower the replacement costs.

LumenCare Mode

The LumenCare Mode, which adjusts projector lamp power in gain steps until full power is reached, effectively maximizes power saving and reduces brightness decay. It's the first and only projection feature on market that ensures three years of consistent image brightness for optimal learning and teaching.

Eco Blank Mode

The Eco Blank mode allows teachers to blank the projection screen whenever they need to direct their students' focus back on them – or simply when the projector is not in use. When activated, this special feature dims the lamp power automatically, lowering the total power consumption by 70%.
