Frequently sked Questions
The quaRay Control Unit has two channels
– does it work for just one light unit?
Yes. To control a single quaBeam, plug the
power supply into Input 1 and plug the
quaBeam into Channel 1. The controller will
now control the single quaRay using the input
settings for Channel 1.
What is the colour temperature of
moonlight, and how do I simulate this?
Light from the moon is actually just light from
the sun that is reflected back to the Earth.
Moonlight is therefore the same colour temperature
as daylight, just not as bright.
The simplest way to simulate a moonlight
photoperiod is to set one or both channels of
your quaRay Control unit to ramp down from
full power to 5% or 10% overnight, before
ramping up again at sunrise.
My lights appear to dim very slowly at first,
then suddenly appear noticeably dimmer
very quickly – why is this?
This is because the human eye does not register
small differences in brightness until overall light
levels drop below approximately 40% of
"normal" brightness. t sunset, for example, it
does not appear to be getting darker until dusk
when light levels reach around 40% of full daylight,
and then it seems to get dark quite suddenly.
Useful Tip: the shorter the ramp down period, the
more noticeable this effect will be. To minimise
the appearance of sudden dimming, set your
quaRay Control unit to ramp down over a
longer period of time.
