So i had a Very interesting discussion with a customer who bought some new light fixtures off amazon.
As I look at the box i notice something missing. No UL or CUL ( Underwriters Laboratory ) ( Canada Underwriters Laboratory or sticker on the box . I inspect the light fixture also no tag or sticker.
I tell the customer its illegal to install this fixture , its a potential fire hazard The customer was taken back by this. How can that be I bought it off Amazon. I then state that Amazon has lots of 3rd party sales ( cheap knockoff light fixtures ) that hasn't been tested and approved by U.L. or C.U.L.
In the United States every electrical device from blenders to appliances ,Tvs, hairdryers anything that plugs MUST have a U.L. or C.U.L.tag on it.

Now you know...
Buyer beware

P.s.a. on smoke detectors and smoke / carbon monoxide detectors.
How to tell when they expire.
Where to find the manufacturer date .
Recommend replacement is 1 combination carbon monoxide / smoke detector with photo electric sensor with voice not ionization sensing 115 volt hardwired with 10 year lithium battery on each level of your home.
Pending on the year built or upgradeds you may have smoke detectors in each bedroom and living area top / bottom of stairs .
Once you satisfied the 1 combination smoke / Carbon monoxide detector on each level of your house the other detectors can be only smoke detectors in living areas for the most part. Those smoke detectors should be hard wired 115v with battery backup photo electric sensor NOT ionization.
I strongly recommend 115 volt with backup lithium battery sealed unit . No need to replace batteries ever , they are usually a 10 year device.
Smoke detectors should be replaced every 10 years / combination smoke and carbon monoxide every 7 years or per manufacturer specifications.

Remember this
A smoke detector needs to be in working order to protect you your family and property .

Any questions please reach out to your local fire department fire prevention officer they will be glad to answer any questions.

If you need replacement I can be reach at 781-789-1107
