DiCUNO G4 LED Bulbs 2W, 20W Halogen Equivalent G4 Bi-Pin LED Light Bulbs, Cool White 6000K, 12V Non-Dimmable Light for Home Lighting, 200LM, Pack of 10

I use these bulbs all the time in a number of light fittings and have no real complaint, even though they don't last quite as long as I was expecting.

You get a good lot of these for the money and they fit in the G4 lamp holder well enough and even cope with being used as a halogen replacement without making any changes to the 12v supplier (a cooker hood in my case) . The problem is that they are not very bright. It seems that they are roughly half the light output of the halogen equivalent: 150-200 lumens instead of 350 - 400 for the halogen and this for the same nominal power consumption of 20w. I need to see what I'm dong so have given up with these and ordered some halogen ones instead. Can't comment on their longevity as they have only been fitted for a few days.

Used in combination with a dimmable driver. Sometimes flickered at maximum brightness. That might have been caused by the driver - can't tell. Dimming worked fine, even though bulbs not supposed to be dimmable.

Very good value and a lovely warm ambient light, can't say anything about longevity as only had them a few days but if they last as they should I would give five stars.Great value for money if they stand the test of time

We have a ceiling lamp with 6 halogen bulbs however it appears you cannot replace all of the bulbs with these led ones. When I tried the bulbs came on for a second then went off, however if I leave one of the halogen bulbs in situ it works but of course the colour is different.

After quite a few failed attempts at getting a decent G4 LED replcement, I went for these Dicuno bulbs. Wow, they are absolutely brilliant. I actually think they are brighter than advertised but that's subjective of course. They are of a tapered design and fit in a very tight space in our down-lighters. A great product!

I only just installed these 10 bulb in under cabinet lighting and picture lights - they all worked fine and do NOT flicker. The light is bright, brighter than those 2/3 year old LED bulbs, 3 of which had stopped working and others had started to flicker - which I replaced . Whilst I cannot leave a review as to how long these will last - No problems to report thus far, I would invest in these again.

Her Indoors bought this mahoosive light fitting with 24 10w halogen lamps. I have instantly reduced the power consumption by 80%. They look better than I thought they would, you don't notice the yellow LED panels at all unless you are really paying attention.
