Water feature supply

[pickleye]

Hi,

Mother-out-law just bought a Ex-displaywater feature with numerous blue LED's. Supposed to be fully working, but, no supply for the LED's.

It looks like the original pump has given up and been replaced with a small pond pump. The wires to the LED's have been cut off. She doesn't want to take it back as she loves it and has an electrician in the family who can sort it out, Grrrr!!

I fitted a new water feature a while ago which had a transformer feeding an elv pump which had a fly lead feeding the LEDs. I guess this is what this one had originally. Different brand and was sent back fautly, so cant check voltage etc.

Any ideas for the best way of feeding the LEDs - I don't even know what voltage they operate off. I assumed 12v but looked at blue LEDs and most were 4.5v. I have no packaging or manufacturer data and can't find it on tinternet.

Can you go back to the supplier for info mate, ask Mum to flutter her eyelids! ]

 

[pickleye]

No manufacturer for the one she wants to keep as ex display/no stock. Good thinking, I'll have a word with the garden centre at the weekend to see if they can help. I'll mention that they need to learn how to wire a plug too (L/N reversed)

The one that went back faulty was a different make/style/brand but had what i asume was the way the LEDs are supplied.

Chance of work here mate, offer to help them out checking out the wiring out on their displays to ensure that they are safe, remember no part P here commercial, if they sort out the info you need, probably only half a day to check it all out?...

never looked at it like that before. Worth a thought.

I Turned down a job the other day in a school, 3m of dado trunking. They'd asked our company to quote, then asked me to do it cheaper. I've been working there for best part of 9 months, so they had my number. Just seems wrong to bite the hand that feeds you.

pickle,

good thought process,

dont undercut your boss.

 

[pickleye]

thanks steps, put me in a very uncomfortable position, didn't want to take no for an answer.

Very funny that he didn't want "qualified" lad to do it as "seen his work". Liked mine better. Made my day, but still no!

I'm hopeless with LEDs but what about asking your wholesaler to ask one of the reps what size driver unit you need.

 

[steptoe]

Deke, they just sell a box that has lights inside it, they havent got a clue

It'll most likely be something the wholesaler won't be able to supply, as it's highly unlikely that they require a high power LED driver (1/3/7W). Remember that LEDs can't be driven by a constant voltage, so unless they already have some form of current limiting you'll end up blowing them all if you connect just a normal transformer to them.
