LED room lighting (again)

[hellymedic]

Having posted about frequent failure of the R63s in my kitchen, I saw these were on Special Offer at Sainsbury's last week, so stocked up.

It's now a year since I replaced a kitchen lamp and my 'bargains' might never be used...

North lamp in my kitchen has failed after 3 years.
That's about 6500 hours at 6 hours per day every day.
East has not been replaced since I started keeping records in 2017.
South has been replaced 5 times.
West has been replaced 3 times.

E decided that a small chandelier in the window of our local antiquarian book-seller would be perfect for the vestibule.  It's metal-framed with chain and metal ceiling rose. 

On removing the old fitting I found we have 2-core lighting wiring, so metal fittings not allowed.  My solution was to use an LED driver to convert to 12v and source a suitable LED bulb (found one under bus & caravan fittings).

Separately, I have been replacing the 12v halogen downlighters in the dining room with LEDs, until I fried the transformer.  So a replacement driver bought, which is when I discovered that a 25w driver won't cope with 20 watts of LEDs (at least the make I bought), so I had to daisychain another one.  Everything works now. 

The hall is also 12v downlighters, so that's going to need attention at some point as I replace the current lamps.  Only trouble is the hallway is about 25ft long and I've no idea where the transformer is (somewhere under the landing floor).

I suspect you'll get issues with voltage drop.

More than with the current 12v halogen lamps?

Under-volted halogen will just be a bit dim.

Under volted leds might not work.

Oh well.  Here's hoping I don't have to take too much floorboarding (and carpet) up.

Probably easier to take out the ceiling from below;)




Or is that for shower traps…
