This LED started flickering the other night. I assume that the LED is failing.

 

As you can see from the photo it is screwed in and soldered directly to the wiring. The lamp carries a note on the base saying that the LED is not replaceable but I would think that by unsoldering and unscrewing I could put a new LED in place. That is if I knew where to buy it and what to ask for.

 

Anybody out there have advice about this?

 

[EDIT - Corrected to LED from LCD - Silly me 😀]

So first of all I fixed the post so it reads LED not LCD. I put it down to old age 😅.

 

Dimensions are 20mm I think. Measured across widest points.

 

The only writing I can see on the LED itself is M19-01L

 

The base sticker reads:

Sweet, I have these two, I suspect the bottom will fit - but I believe it is only 3W?

 

They were handed to me without any info unfortunately. 

 

The upper may suit as a higher wattage - but you'll need to jerry rig a mount.

 

You're more than welcome to have both/either for free. 

Pm me if you're keen, or wait to see if anyone here can confirm if either may work?

LEDs typically burn out suddenly or go dim, whereas flicker in my experience more often comes from a faulty driver. There's probably a driver circuit in the base of the lamp and if that's the problem then sadly it's probably cheaper (and safer) to buy a new lamp.

Also the top of the two LED replacements pictured has inline resistors, so won't be a suitable replacement. The other one may be suitable if it's rated for the same forward current, but hard to say without comparing data sheets.

Rather than PM you - I have decided not to try and change the LED. After the advice from @pih I am going with the driver as being the issue.

 

Thanks for your kind offer.

Thanks for the advice. I guess this lamp is going to tip.
