Why the g4 or gu5.3 (mr16) bulb is flickering or not working at all?
Gu5.3 (mr16) and g4 bulbs usually works from 12 volts.
1 bulb single using will be flickering maybe. Hi, i recently purchased my first house which has halogen spotlights i'm several rooms. I found my gu5.3 fittings with led bulbs were a failure even though a real transformer so should have worked only got around 3 months life where the gu10 bulbs never had one fail. Led g4 3 watt 12v ac/dc bulb.
We took some measurements too.
So i pushed them to make sure they were properly 'in' and all seemed fine. All connections were tight, bulbs were a reasonable quality and. It would probably be easiest to buy a set of 3 g4 halogen cabinet lights and use the parts from that to fit your existing fittings. So although gu5.3 or g4 bulbs need a rectifier as can be put in either way around they still often need a dc regulated supply the peaks on a 50 hz supply is too much for the led.
Yes, in many cases, you can simply replace your bulbs separately, one by one.
Shop our led g4 3w bulbs now. Also, halogen supplies provide a very chopped up waveform that halogen lamps do not care about. Answer a few questions so that we can help resolve this issue: My in laws' kitchen has worktop lights with 12v 20w g4 lamps in them.
The g4 led bulb measures:
The bulbs haven't usually blown, but they suffer from bad connections in the fitting. This light bulb was a replacement for one in. They tend to get used a lot because there's not much natural light, but every time we visit (most weekends) i end up having to sort out one or two failed bulbs. Many of the old halogen transformers do not recognise the led bulbs that are connected in the circuit and do not give enough or any power to drive them.

The reason is that led lights need a different transformer from the halogens. As mentioned before, most of the g4 leds operate on dc voltage, so they will need a different power supply or transformer to operate.
When i reverted back to fluorescent bulbs, all but one work.
A couple weeks ago, some of the fluorescent bulbs randomly stopped working.

Look for a transformer that has a minimum load rating of 0w such as these tlc one's.
99 ( $2.67 $2.67 / count) If you hook them up to a 12 volt ac transformer, too much electricity will run through the bulb and it will pop. The result is that the user thinks that the bulbs do not work, when in fact they maybe perfectly ok. As above, a compatible led driver should solve the problem, replace the halogen transformer.
