Lightsheer - 5ms settings possible at 40j?

Can the Lightsheer laser used for hair removal be set to a 5 ms pulse width even when the power is set to 40 Joules?

Most clinics use LightSheer on auto setting of 30ms.

I mean is it possible to set this machine manually to 5ms even at high power joules?

Are you saying it’s not possible to set it at auto at less than 20J?
