In addition, one may also apen a door that causes the alarm light to go on if that light is not visible, i.e. you placed the light behind the sheetrock.
this could well be because the light is a cold led combined with other reasons and probably your Rav does not hold like the Chazon Ish. Would your Rav allow this if it was a 50 watt bulb? or if it ignited a flame?
