Are you ok with the concept of connecting things up in series and/or in parallel?
I just noticed @Hippo mentioned wiring them up in parallel and don't want to be patronising but you never know!

This is a great thread which explains the benefits and disadvantages of wiring in series, or parallel or series/parallel.

You'll be getting used to the symbol for a diode by now! The funny arrow type thing which shows that the current can only flow one way through one.
10 lamps would prolly be too much for a single series circuit anyway.
I'm going to wire 6 up and try it, can always wire them in sixes if they go dim with numbers 🙂

To give them all 12v oft yer power yer need to wire them in parallel. All LED positive connect together. All LED negative (0v), connected together. Yer can do it by daisy chaining them. If yer put 6 in series then each obe will get a 6th of the 12 volts. So they will be dim.
 
See the gp, lay it on really thick and get on to allopurinol. You must be gout-free for a month before you start. Until then, paracetamol & codeine with ibuprofen will take the edge off it. My problem is that I can’t use ibuprofen tablets because I’m on chemotherapy and the combo isn’t good.
My brother has been on allopurinol for a decade and it has made life very much easier for him.

Sour cherry juice works well too ...
 
...that now the Central Heating system is up the creek.
One bathroom the rad is boiling, tother bathroom the rad is OK, not as hot as the other but still as hot as would be OK, but all the other rads in the house are cold.
All rads are full of water, bled them and no air came out. bled the nozzle thing on top of the tank, highest bit of pipework on the system, a bit of air came out but not much. Did all this with the system switched off and the boiler off. So no air could be sucked in.
Boiler going full blast, pump working.
The header tank in the loft for the CH has water in it and the ball valve is working
This has all happened since this afternoon's shenanigans with trying to drain the hot water. At least there is still hot water coming out of the tank.
All the gate valves are fully open although one on a pipe leading to the bottom of the tank barely moves in either direction. Never played with it before so do not know if this is normal or not, but I don't think I have closed it then been unable to open it.

What the flip have I done?

The plumber coincidentally came round this afternoon to pick up his cheque. This problem hadn't shown itself by that time but we discussed gate valves, he reckoned that they often played up and you ended up having to replace them with the ball valve type with a decent lever on them as a handle. I told him about not being able to turn the hot water off to the taps. He offered to "have a look" I told him I'd get in touch if I couldn't solve it.
Now it seems this is the least of my worries.

Turned off both the bathroom rads wondering if I haven't somehow got an airlock in the system, but that would seem to be a massive airlock.
Inlet pipes to rads are very hot, but the rads themselves, no. It is as if some one has turned all those rads off.
I'll wait until others heat up and turn them off one by one. I have had an airlock before but it was always in one rad and shutting off others improved it.

Did I mention how I hate plumbing? Give me any other sort of DIY any day.
W has gone to bed and left me to play.
 
...funny thing.
W went over to the "chocolate cupboard " this evening. One that only rarely gets opened and never by me.
She sits down and opens.......

an Easter egg.

Apparently it was the one I gave her months ago.

The mind boggles.
(Big thing made of dark chocolate like she likes. In a red box. Hmm!)
