A Blast From The Past

[securespark]

Who remembers these?


They weigh a ton! 3138g, in fact!

Just brought one back from my Ma's. Middle lad helped me remove it a while back when we converted a run of 4 SELV down lighters to 230V LEDs.

Built to last though. Still going strong, since installation in 1990. Only one lamp had been changed in all that time. The originals were Thorn open-fronted 50W dichroics.

Shame it's going on the tip...

Unfortunately I do remember them, It's an age thing!.
Digressing, how did you get the emoji jobbie?, when I add a smiley face it doesn't appear.
Probably something dumb I'm missing, lol.
EDIT-just realised, doh

Just realised, appreciate the reply though

She is possibly safer without it, went to a few premises where similar had caused fires, I believe the invidual outputs were not protected just all commoned up to the one transformer output and back in the days 50w lamps were common,. and when the 12 volt lampholder wires burnt up and shorted, extreme currents flowed sometimes burning up the cable from fitting right back to the transformer, eventually makers added fuses to each output but even then the 10 amp fuses often blew.
Often installers wrongly thought they could just use small flex due to being a low 12 volt
You could buy fused splitter units but were rarely used as well as a special twin flat cable that was an obscure size roughly 2.6 or something mm

Keep it and run some 12v led tape round your garden

Not only do I remember them, I have a couple in an enclosure which I used to use for outside 24V christmas lights, also another pair similar to Rocky's pic for the same purpose.

I have a customer who has 2 in use and insists on keeping his 20W and 50W spotlights going.

On ac?

I haven't seen that. Used to do a lot of shop installs.

But it's true that many did not understand the higher current and the need for thicker cable.

I might even still have a brand new one in a cupboard somewhere!....

I have the same problem with some products.

Do you recall the single 50va units that also weighed a ton and had little 3.15 A fuses built in the end that often blew, i see you had open front dichrolcs thats pretty old school.
12v seemed to really change shopfittiing till then round here was all Concord track and crown silver es lamps.

Hows your tester?

 

[securespark]

I do recall the 50VA units, but didn't use them, at that time I was doing shop stuff and it was the bigger units I was using.

Hows your tester?

Not sure what you mean!

 

[morqthana]

also another pair similar to Rocky's pic

Hope not!

Me too. Well - new-ish. About the size of a shoebox.
