sensor based indoor light fittings?

Postby callagga » Mon Apr 15, 2013 12:44 pm

Anyone know of any relatively cheap sensor based light fittings for indoor lights (e.g. bedrooms, kitchens etc etc)? To try to save money on lights that are not turned off. What brand/models & where to get & price?


I've only managed to find some overseas so far at:

I think Jaycar sell a couple of different IR motion sensors, I have one floating around here somewhere, but haven't put it to use yet.

Arlec and clipsal make a recessed sensor about 6cm round that can be wired to existing lights.

I have used such devices for years in bathrooms and the likes..
HPM sensor switches, just go in place of the normal switch..
Problem is that you have to keep moving..
Ie. You can't sit and read on the Lou...

To be fair... Don't know what they would do with a 5w led globe...

Also great for exhaust fans to keep running for say five minutes when needed most...

Hi Tracker - do you mean like this? http://www.hpm.com.au/products.aspx?pid ... ght-Sensor

Had not thought of a sensor near the switch. Would they work as well however as one mounted in the ceiling? in terms of noticing movement throughout the room?

I've noticed the new Woolies at Holmview in Qld, and I assume their other new stores now have the sensor lighting on their upright freezers, which is a great idea.

However they've completely defeated the purpose of them by angling the sensor to operate the lights whenever anyone gets withing about 10 metres away, and also set the delay to the maximum setting, so the light remain on for as long as possible.

Great idea to save electricity, but clearly totally clueless by adjusting them to stay on as long as possible. I even went to the effort of pointing them downwards and reduce the time delay, only to see them changed back the next week when I next went shopping there. :lol:

In the case of Woolies I'd expect that they're more concerned about marketing than energy consumption.

Someone goes near the freezer so it suddenly lights up and grabs their attention. No doubt some marketing guru has concluded that this is likely to increase sales.

Energy consumption would be a secondary consideration I'd think. That is, they'd still do it even if it increased energy use as long as the increase was less than the expected sales benefit. That it actually saves energy is a bonus.

You might be right about that, but if the lights are effectively staying on all the time it then defeats the marketing purpose of attracting attention, doesn't it ? :)

I thought the politically correct thought of saving the planet was the idea of it.

I can remember back when I used to work in supermarket management in the mid-80's, they took half the flouro tubes out (but left the ballasts hooked up), as an attempt to reduce costs.

Sorry - did not see your question..

My device is actually a HPM architrave switch.

BUT - interestingly I found this device by clipsal..
I think it just fits into a normal switch plate.. (with a bigger hole in the timber... )

Search both sites Clipsal.com.au and HPM.com.au for "Motion Sensor"

I may be wrong, but are the ballasts not in series with the tube---- hence no tube=no current..???

it's a long time since I thought about a typical Flouro Fitting..
