I am planning to use a photocell (eg Screwfix cat no 11330, max load
capacity 5A) to trigger 6 external lights. These will be low-energy 16w 2-D
fittings. Will this work, or do I need a specific type of photocell to drive
Thanks for any help.
I'd suspect that one is "a flasher" (search back on this ng). It
bleeds a little current through the lamps to power the photocell
circuit. It'll work, but occasionally this current is enough to
trigger a flash from one of the lamps. Using a simple relay would
Ignore me if anyone has tried it, with this particular unit.
I suspect you may be right Andy, but I also think that the current through
the relay will not be enough to feed the little bleeder ;-), such circuits need
a 60W or so incandescent to work.
To the OP, if you buy this and it has a neutral connection then it sounds
ok, if not then beware. If it turns out not to have a neutral, then you would
need a 60W incandescent load in the circuit too, not very energy efficient
I had a look at ones on tlc but they have minimal info of this point too.
btw: My experience relates to PIRs not 'photcells'.
Apart from the concerns raised by others 2D lights are very lethargic
about getting up to full brightness especially in cold weather when
they can take 5 or 10 minutes to get a decent light output. Unless
you expect the lights to be on for a long time incandescent may well
be a better choice.
