Anyone any idea what these symbols mean?

As per title. Does anyone know what this symbol means? It’s on a IP rated outdoor light and there’s nothing in the instructions to say what it means.

Customer asked to me to take a look at a light she intends to by 10 of for her garden. This symbol was on it and I’ve never seen it before.

The picture on the left looks like a broken lens or something ? does it mean fix any broken lenses

 

[littlespark]

Yes. Replace broken glass.

I’ve seen similar square icons on old halogen floodlights.

Thanks. Odd if that is what it means as it appears to be a sealed unit apart from the cable entry and mount.

Possibly just a generic sticker that gets stuck on anything and everything that has a glass lens ? regardless if its replaceable or not...

I never sleep well in this heat , been waking up around 5.30 most mornings

Just means I can get some paperwork done before heading out which means when I get in I don't have to do it

I sleep like a log once the heat of the day is gone. not been much else to do all week. lightning fried my router and house phones. mobile is in repair shop for new screen, lost back-up phone, had a £160 bill to get drains unblocked. beer fund sadly depleted. still not walking right since hip op, but improving slowly. still, there's many younger men in a worse state, so can't grumble.

Never thought you’d find that in 7671

Me neither, but it is in Table 55.3 (Blue book p.222)

It's time you painted it brown.

I don’t think there’s any changes since blue on that particular page….

Good to know you can find useful information in the big book though

It's an important symbol, the front glass on some light fittings is essential for blocking harmful UVC.

That's a bummer. At one time the BT master socket might have had an earth wire so the SPD would drop common mode surges to earth, but not seen that for ages. Fine if its a old fashioned analogue phone only connected the the phone line, but with most stuff now being powered that lack of common-mode protection means it has to deal with several kV internally.

They could be properly engineered to do so, but that would rob the shareholders of precious pennies on every sale.

Indeed, the loss of beer money is sad but nothing compared to what some folks have to face as you say.

From this site (my emphasis):

https://telephonesuk.org.uk/wiring-info/

In more recent years NTE5 or CTE5 Lineboxes are fitted in place of master sockets, these have a removable (lower half) panel which house the terminals to connect wiring to the secondary sockets. § Terminal pins 1 and 6 may be absent on some versions of C/NTE5, but these connections are not normally used anyway. The NTE5 tends to have the same components inside as a master LJU, however later NTE5 sockets differ by not having a surge arrestor, have only pins 2, 3, 4 & 5 or 2, 3 & 5 connected, they also have a small coil in series with the ‘bell wire’ on pin 3 which acts as a filter.

So the bar-stewards don't even try any more!

For the cost of a few beers:

No idea how good, I would be tempted to open one and look. Still, if you are in London, price of one beer!
