Simba Lighting LED G4 1.5W 12V AC/DC T4 JC Bulb, Bi-Pin Base, 3000K, 5 Pack

Got these to replace some cabinet lighting in the kitchen. Three points: - The bulbs' base is true G4 fit, but the lighting element or bulb itself is quite a bit larger in both length and diameter than my OEM G4 bulbs. Fortunately I had enough clearance to fit these in there. If your fixture is completely flush with the existing bulbs, this might not work for you. - The bulb doesn't offer true 360 degree light coverage. It's set up as a PCB board with LEDs on both sides. Light projects up and down, so you do get a noticeable drop in light output at the 90 and 270 degrees position. For G4 bases, I think most if not all are oriented horizontally so this shouldn't be an issue. - The light produced is closer to 3000k than 2700k, as expected. Also the bulbs are indeed dimmable. The difference between high and low isn't as pronounced as with the OEM bulb, but there is definitely a noticeable difference. That's good enough for me. All in all, as long as they hold up over time, this was a good buy. I will update about longevity later on.

Bought these to replace the G4 10watt bulbs in the IKEA in cabinet puck lights that had the halogen bulbs. Same color exactly the same as the halogens, just what I wanted. Same brightness also but uses much less power and doesn’t get hot. They do make a very low level buzz noise. I noticed but the wife didn’t. It’s not annoying, barely noticeable. No flickering, we have it in a timer and stays on for several hours each day. So far so good and it’s been about several weeks already.

I replaced these bayonet light bulbs in our boat fixtures with these LEDs. They work perfectly. I did have one bad LED in the bunch thus not a full star rating.

Sufficient output for my landscape lights. They last at least a year in the heat of the Californai desert.

The packaging, the product itself well made only needed one. The others will remain as spares.

Looks like it works but it is MUCH thicker than my halogens--so the chandelier shade does not fit over the bulb. I have a chandelier that has glass globes around the bulb, sort of a modern like bubble lamp. I ordered both LED and halogen replacements to compare the light but am not able to use these.

Bought these to replace Halogen bulbs for under counter kitchen lights. Halogens were nice but burned so hot that canned goods and spices in the cabinets were warm. These bulbs were a little longer but still fit in the pucks. Easy switch out. Brightness looks equal to the halogen but does not get so hot. They say no flickering but will if you replace all halogen bulbs with them. It is not the bulbs fault but related to the transformer. In all, I am happy with the results.

Yeah, this was what I wanted: pleny of 2700 Kelvin brightness at about 7-8% of the power draw and heat of the original 12VAC halogen turds. I replaced every cabinet light in my kitchen with these and the place is just as well lit but with almost no heat at all. It's hard to tell they are on, they're so cool to touch. Can't measure absolute light output, but I'd guess in the 100-120 lumen range per unit. Don't even bother thinking about it -- just replace all those old hair dryer heating elements with these LEDs and watch yer zotz bill fall.
