Pack of 3 G4 LED Spotlight Bulbs 1.5 W 24 SMD 12 V DC 125 Lumen 360° Illumination for Dimmer Switches Halogen-Shaped Pin Cap Halogen Replacement Warm White

For people that dont know..I bought these to replace 6 x 20W halogen bulbs in a dimmable standard lamp and 2 x 20W in a dimmable ceiling light.When all 6 were in the lamp, the lamp did not work because there was not enough load on the transformer ie 6 x 1.5W = 9W and the transformer expects 6 x 20W = 120W. They work now because I left 1 x 20W bulb in and that is enough for the transformer to work. One of them died after 4 hours though.In the ceiling light if I used all 6 they worked but the transformer buzzed loudly and I ended up putting 2 x 20W bulbs back in to stop it making the noise.I since have found out that in reality you should buy a proper LED transformer as the low wattage of these bulbs will cause problems like the ones I experienced. My only problem is that the transformers are built in to my light fittings!

Great bulbs, every single one worked 👍🏻

Not as bright as I expected and the colour was almost grey. They only just fitted inside the shades on my light fitting.

Great replacement for normal bulbs

doesn't work

I have a 3, 21 watt bulb chandeliers (G4 10w) and would like to replace the bulbs with LED. One snag is that the LED bulbs must not have a diameter greater than 10mm, so these bulbs seemed idealThe chandelier has three rings of bulbs with three transformers, one for each ring.One ring has only 3 bulbs, so I replaced this ring with the LED and turned the light on, they didn't work :-((I then knocked up a bench test circuit with a correct LED transformer. It worked a treat and was very very brightNow to save my pennies to buy 21 bulbs and three transformers and find time to fit thm allSo if you want these to work, get the correct transformer

I bought a miniature light fitting ( at great cost ) shaped like a small lamppost to illuminate a china figure, and my chief concern was would the bulb fit into it, the lamp had a 13 amp plug integral with a transparent cover to it,s power supply and that showed both a transformer and internal rectifiers so I could safely assume that it was a DC supply, I had to shorten the pins so the lamp top fitted correctly, and this did not cause a problem, it now consumes 1.5W instead of 20W so it runs cooler and at a great saving in power consumption.

Very good quality, no bigger than a standard halogen light bulb, so can be a direct substitution. Good brightness equivalent to 20 Watts incandescent. You must use a DC transformer with these, so make due allowance when pricing and consider also that some light fittings have built in transformers, so check first before ordering. They don't work with an ac transformer.
