These LED lamps are direct replacement for AC driven halogens. Their internal circuitry handles AC/DC conversion. Gives very bright light, on par with 10W halogens. Color temperature is also indistinguishable from halogens. If you have an halogen power supply that drives several of halogen G4s in parallel, do not change all of them with LED G4s. Your power supply needs a minimum load to work stably and you might need to keep one or two of old halogens to provide this minimum load.

These bulbs are very bright. The dimensions on the website are misleading. The width is given for the narrow top part, not the wider base part. They won't fit in the opening I have.

I used this bulbs in motorhome, very good product, better luminosity without heating as halogen 10W bulbs.

Used in my campingcar for replacing 10W halogen light. First LED bulb finded better in luminosity, without heating and with agreeable specter of color.

Best G4 bulb by a long shot (of 1/2 dozen I've tried). At least equivalent to a 10w halogen maybe more. Measures 1.7w, and the buck regulator makes it more efficient (current decreases as voltage increases to keep same wattage, no resistor to waste power). Good illumination end-on except for a very narrow band. Best bulb for this power rating.

This is pretty good substitute for G4 halogen bulb. The shipment arrived to Central Europe in about 7-10 days. Quality of the packing is good, manufacturer name and conformity to CE standard is clearly listed on a box (not case with other bulbs ordered on website). The bulb itself is maiden in good quality. Dimensions are as listed, however it is still something bigger then classic halogen G4 lamp, so it might not fit in all lamps. Emitting spectra is moved toward cold colors, for example I ordered warm white and the bulbs are emitting in neutral white spectra (approx. 4K). The color of the light is very pleasant (like daylight). 2W / 200 lumens are for sure met. Previously on the same spot I used 25 W G4 halogen lump and this led light emits more light. Installation requires some special attention - polycarbonate body is very fragile (I broke one in process of installation). I would recommend this bulb.

I love these lamps. They are very powerful, brighter and at insanely low power consumption

I had to replace 10W halogen bulbs and it is almost the same or a little bit more brightness. The color of warm white is good. The size is perfect and fits perfect

expensive but good! warm white is almost exact the same as a traditional bulb, you will not see the difference in color. normal white is indeed a lot "whiter" than traditional bulb but a nice cold color. 99% of the buyers should go for the warm white. the housing is made of flexible silicone, not plastic.

I dare to say that it is brighter than my halogen 10w bulbs, recomended!!
