Reasons For

9 Reasons For
Higher vertical synchronization (max) Edit
Acer K137 is 0.12kHz maximum vertical synchronization, but the Ricoh PJ X2240 is only a 0.09kHz maximum vertical synchronization projector (0.03kHz lower).
Longer service life of lamp (economic mode) Edit
The Acer K137 is a 30,000h service life of lamp in economic mode projector. That's 24,000h longer than the Ricoh PJ X2240 (6,000h).
Longer service life of lamp Edit
The Acer K137 has a service life of lamp of 20,000h. That's 15,500h longer than the Ricoh PJ X2240 (4,500h).
Moderately quieter noise level Edit
The Acer K137 has a noise level of 31dB, but the Ricoh PJ X2240 is a 34dB noise level projector (3dB louder). Read more

The noise level of the projector is the amount of noise that the projector makes (caused by the cooling fan inside the projector) when it is running.

A lower noise level means that the projector will be quieter when it is running. This means that you will be able to appreciate the quieter parts of films better without the background noise of the projector running.

Quieter noise level (economic mode) Edit
The Acer K137 has a noise level (economic mode) of 29dB. That's 2dB quieter than the Ricoh PJ X2240 (31dB).
Higher RMS rated power Edit
The Acer K137 is a 3W RMS rated power projector. That's 1W higher than the Ricoh PJ X2240 (2W).
Two number of built-in speakerss Edit
The number of number of built-in speakerss on the Acer K137 is two, but the Ricoh PJ X2240 only has one number of built-in speakers.
5x lighter Edit
Acer K137 is 510g heavy. That's 2.1kg lighter than the Ricoh PJ X2240 (2.6kg).
$44.89 cheaper to run
The Acer K137 only costs $21.44 to run over five years whereas the Ricoh PJ X2240 costs $66.33 to run (209% more). Read more
3 Reasons For
