Replacement 12v LED for brass 'dome' lamp fittings

Are you sure they have replaceable bulbs? To save money many devices have integrated leds.

It's not necessarily to save money. Often the problem with LED bulbs in certain fittings is heat which kills the LEDs or associated electronics. Many of the fitting with non-replaceable LEDS have the LEDS attached to relatively large heat-sinks which extends the life of the LED.

Lamps glow…bulbs grow…;-)

without pics its hard to tell. As others have said can you change the "bulbs"? Do you want to keep the fittings?

My experience with LEDS is that light output per watt hasn't changed so for more light you need more watts. If these are these mains, probably ok, 12v or 24v might need a new driver/transformer.

However, I have found that, for me, colour temp makes a big difference. I now go for the highest I can find. Swapping a "Warm white" for a "cool white" seems to make a big difference, appears much brighter. Has transformed both my loo and bathroom. It doesn't look like incandescent, but if I really want that I get multi-colour...

One problem, of course, is using led bulbs in old fittings made for incandescent bulbs. The driver generally goes as even with low-powered leds they eventually get heat stress, but that's not what's at issue here.

Those fittings designed with large heat sinks are for lighting in very inaccessible places, and would cost accordingly for their long life. Domestic lighting is made to a certain (usually low) price. You've also go the issue of the leds very slowly getting dimmer as they age. Perhaps not so much as incandescent and even fluorescent lamps, but it does occur, and they eventually require replacement.

Integrated led lighting is ideal for today's "throwaway society". I would never install one as, other than mentioned above, the whole premise is a con. Why replace just a cheap bulb when you can replace a much more expensive unit? If the manufacturers had to pay for the labour of replacement and the recycling/landfill cost, as well as the fitting itself, perhaps they wouldn't be so keen on selling them.

I crimped the connections to the SMD LEDs myself so they're definitely replaceable! :-)

You've all got the wrong end of the stick, well fairly the wrong end.

These are LED ceiling lights on a boat, supplied with 12 volts. I bought the 'traditional' brass 'dome' fittings many years ago and stuck the square SMD LED 'bulbs' in them myself. They just hang loose on the wires inside the fittings and mostly point in the right direction. :-)

I was just thinking that there might be more efficient LED 'bulbs' around nowadays that I could install.
