Anyone know of a photocell light adapter (to implement dusk-to-dawn on/off
on an existing light fixture) that doesn't cut the light output of the bulb
(at least not significantly)?
I've tried these screw-in adapters from the hardware stores and they work,
but they bring the light output of a 100-watt bulb down to about that of a
60-watt bulb (or maybe even less). I've tried using a 150-watt utility bulb
and that didn't make any difference.
Hardwire or screw in? If hardwire, get one that says it's for
fluorescent fixtures. What you have is the cheap screw in type that is
basically a resistor to the lamp, which causes dimming.
The higher end sensors that you wire into the light are actual on/off
I was about to post a similar question about 4 or 7 watt night lites that come
I find that the 4 watt old style nite lite where you SWITCH it on and off is
MUCH BRIGHTER than the 7 watt automatic on nite lite.
Any reason why ?
Obviously there is a resistor of some kind.
Long ago I measured the voltage at the bulb terminals and it was DEFINITELY
LOWER on the automatic vs the manual switch type of nite lite.
Forgot what the readings were.
Aube makes a wall switch wired adapter (not a photocell) that has a chip
in it that adjusts for daily sunrise/sunset changes, daylight savings,
etc., and you can program on-off to be +/- x min/hrs from
sunset/sunrise. Approx. $35, here's a link to a description:
Use an external sensor with a relay-operated output (rather than the
triac that is used in the lower cost "no relay" sensors).
You could also use a relay operated photocell equipped outdoor timer
like those made by Intermatic and others.
I hope you have better luck with X.10 than I did. Since it is an
unsupervised protocol there is never any way for the tranmitter to know
for sure what state the receiver is in. I once had motion detector /
dusk-to-dawn lights all around my home. In my area we have a lot of
power fluctuations (brief interrruptions) and I was always coming home
to find some or all of the security lights on in the middle of the day.
