General info

1.lamp life

6000h

15000h

This shows the lifespan of the light source. Projectors need to have their lamps (light source) replaced every now and then.
2.thickness

234mm

280mm

We consider a thinner chassis better because it makes the product more compact and portable. Thinness is a feature highlighted by many manufacturers of mobile devices, but it is essential for a wide range of products.
3.height

97mm

130mm

The height represents the vertical dimension of the product. We consider a smaller height better because it assures easy maneuverability.
4.width

323mm

390mm

The width represents the horizontal dimension of the product. We consider a smaller width better because it assures easy maneuverability.
5.weight

3.1kg

5.3kg

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
