Photocell porch light

Discussion in 'Misc DIY' started by Martin Pentreath, Oct 11, 2006.

  1. Hi,

    I put one of these outside my mother's front door a while ago:
    http://www.screwfix.com/app/sfd/cat/pro.jsp?id=14998&ts=98840

    It has a photocell, but she's not very happy with it because it comes
    on too early for her liking and stays on too late. I've tried
    explaining that it only has a 16w bulb in it, so the extra time is
    probably costing her about ten pence a year, but she still frets about
    it. To my mind she doesn't have enough to do, but enough complaining
    about my mother!

    The problem with the lamp is that the photocell is set to be triggered
    when there is still a fair bit of light around, and it's not adjustable
    (in any way that I can see). There's no easy and neat way to put a
    switch in, so I'm now in the market for another photocell porch light
    with an adjustable light sensor (or one that doesn't come on until you
    can't see your hand in front of your face). Any ideas?

    Buy one with a PIR so it only comes on when someone is there.

  3. OK, I think I've solved my own problem - planning to wire the existing
    light to one of these:
    http://www.tlc-direct.co.uk/Products/STNM3000B.html
    This photocell seems much more adjustable, so I should be able to set
    it so that the light is off even when its own internal photocell is
    telling it to be on

    Put a gray filter, or a bit of translucent film/material in front of the
    photocell.

    Isn't that a bit back to front?- it's coming on too early, not too late!
    What is needed is a magnifying glass in front of the lens to trick the
    photocell into thinking its brighter than it is ;->

    Wrong way round, that will make it come on even earlier and stay on
    later.

    in the morning.

    If so the trigger is set at too *high* a light level, therefore a filter
    should reduce the light getting to the photocell and improve the problem.

    I think I would go with Andy and say that the filter will make it come on
    earlier and stay on later.
    What I did with mine was to position some cooking foil just on the wall just
    behind the sensor so it gets more light.
    This makes it come on later and go off sooner.

    *Its* *coming* *on* *too* *early* *triggerred* *by* *falling* *light*
    *level*. Block the light with a filter and it will come on even
    earlier.
