I have bought a few of these lights which are great, dead easy to wire up and give out great white light. My house is quite dark inside.

However they don’t last that long, maybe couple years at most in the most used areas and I have just replaced another couple. Very expensive compared to the old bayonet light bulb!
But I was wondering, would it actually be the Light that fails or would it be the driver as I have spotted a 3 pack of the drivers for a tenner.
I will check next time one goes but wondering if anyone knew or had experience of this?
And on a related theme, our bathroom mirror has one of these touch in built LED lights and demister on it. That light stopped working and I am now wondering if that would also be just the LED driver as the mirror is about £150 to replace!!

It will most likely be the driver - the capacitors will have gone pop inside. You'd need to get a meter on the output to see if there is anything coming out. Cheap drivers will also have a short life of course, but if they're cheap enough....

The lights you link to are 2400 lumens and draw 24w - equivalent light output would need a ~150w filament bulb.
Assuming a saving of 125w per hour at current rates per kwh of 28p is ~3.5p.
This sound trivial - but over a year for (say) 4 hours per day is 1460 hours pa - saving £51.
Summary - it would also annoy me to spend £14 each time the light fails - but it would cost a lot more to revert to old incandescent bulbs (which will eventually become wholly obsolete and unobtainable).

That’s interesting Terry.
Yeah these lights are sometimes on for more than that each day so a good comparison!

Its invariably failure of the driver, capacitors pop, diodes short, resistors stop resisting. Component quality these days is dire

'Tis why G10 LEDs only cost a few pence now though, rather than a tenner or more when they came out!
|

And why car electronics are expensive, remarkably reliable in hostile environments a notable chunk of the cost goes into sourcing, testing, quality assurance, traceability of components used.
