8.3 Mechanism
●
Cooling mechanism and Silent mode
In this model, the air flow mechanism is fundamentally the same as that of LV-7350.
However, the lamp has been changed into 180 watts from 200 watts, as the result, the
amount of heat has been decreased compared with LV-7350. Consequently, the fan
speed could be lowered.
Furthermore noise level has been down to 36 dB(A) from 37 dB(A).
And when the silent mode is selected, the lamp power is controlled to 150 watts, and
the fan speed has been down, as the result this model becomes the more of energy
saving and more silent as 34 dB(A).
Also this model has the system of the automatic fan speed control as same as the
previous models.
