Hello.

 

Would a LED security light - this one to be exact - work over here, from a voltage input perspective.

 

The light it would be replacing is already hard wired to the mains and I was thinking of a simple swap out to add the PIR function. 

 

Cheers

Your link shows a 110V unit so, no good.

Also anything wired to mains must be certified to be used here.




Keep calm, and carry on posting.

It says 

 

 

Input Voltage(V): 85-264V

 

 

so I expect it would work just fine. Many (most?) LEDs are made to work off both 110V and 230V. Vendors like to put lots of keywords in the title so that if someone searches for "110V security light" they'll still hit this product.

 

Look around on AliExpress, so that you can see shipping costs (or free shipping) up front. Shipping can be more than the price of the item.

 

It may be cheaper to get a solar-powered one, by the time you factor in the wiring costs?

 

Regarding certification: maybe one of the certificates pictured is relevant to NZ? Lack of certification could mean your insurance won't cover you if this causes a fire. Or could be blamed as the possible cause of a fire.

As I'm too cheap to wire in lights where needed, I found that mitre10 mega has a bunch of wireless (battery powered) led security lights for upwards of $30. Bought three and just screwed them up where needed, batteries might need replacing in a year or so up perfect if not wanting to have to get a sparkie in.

Stand corrected on the input voltage. Was skimming the product page on my phone and only picked up the 110V bit!

Be careful - some aliexpress devices are rated only to go to 220, 230 or 240v but the nz supply can reach 243.8v within the legal limits. (230v +/- 6%)

 

We have some industrial radio equipment rated for (100-240v) that resets its programming if the power supply exceeds 242v and its not uncommon to find households are getting a supply of 248 to 252 volts. Some other equipment would just switch off until the voltage dropped back down so we regularly call lines companies to lodge faults.

I wonder how long the batteries would last in those LED motion activated lights, given average amount of activation by actual people/cars/cats loitering at night? Might get some to put under the deck/carport.

 

Lots of solar recharging versions on Aliexpress, but I'm skeptical about how well that would work - anyone got them?

I'll get a NZ sourced hard-wired one. 

 

It was just an idea with the Aliexpress ones. 

 

 

 

Cheers for the replies.
