RAYHOO 10pcs G4 LED Bulbs JC Bi-Pin Base Light Bulbs 3W AC/DC 12V 20W-30W T3 Halogen Bulb Replacement Landscape Bulbs(Warm White 3000K)

These are GREAT replacements for the older style halogen bulbs in overhead ranges! They put out great light and are easy to install. Love the updated white light output!

Excellent nice and bright.

I couldn't bear to use the 20W halogen bulbs that came with the 12VAC landscape lights I ordered so I got these as an energy saving alternative. What I wanted was a bulb that had good light output but in the warmer range of color (temperature) so I got the Warm White. Who wants a blinding patch of colorless stark white light? These ARE bright but not so bright that they create glaring pools of distracting light beneath them. They are just right to light my pathways to the entertainment area and down to the dock through the trees.I've had them in for a couple weeks now and all of them are still working perfectly. They are on for around 8 hrs a day. There is no blinking or flutter whatsoever when they're on. I am not attempting to use a dimmer nor is one needed.They ARE just a little longer than the halogen equivalent (around 1/4") and about twice the diameter but it was a non-issue with my lights.I would gladly buy them again when I need more.EDIT: It has been 5 months (give or take a few days) and they are still the same as the day I installed them. Every single one is working perfectly. I am using them with two different transformers having 12VAC output and they work flawlessly.EDIT #2: Going on around 2-1/2 years since they were installed. One and only one failed a few days ago. It didn't fail spectacularly like a firework that never launched. No, it just flickered for a day or three then went out. Here's the interesting part - my area of Florida flooded late last summer/fall and one of the lights down by the canal was completely submerged for months in brackish water. It worked under water!!! Also interesting is the light that failed was never submerged... Go figure! LOL I'm buying more!Correction: 3 of 10 failed within 2 weeks of each other. Looks like I found the lifespan of those.New ones are installed in their place and working great.Edit #3 Had to replace 2 more. 5 out of 10 lasted around 2-1/2 years. Estimated 5000 - 5500 hour operational life span.

I have a variable power supply and tested them from 9 to 20 volts. I also tested them with ac and dc voltages and they worked as expected. I noticed some other reviewers complained that these bulbs get quite hot. And indeed they do if you operate them above 10 volts they get quite warm even at 12 volts. At 20 volts they start out quite bright but quickly dim I didn't run these to destruction but it looks like to me that they will have a much reduced life time at any voltage about 12 volts. This is as described by the seller so you do need to make sure you don't exceed 12 volts or you will definitely experience shorter life time. For me I determined that at 9.5 to 10 volts they are bright enough for my needs and that is the voltage I will be running them at. As an added bonus at this voltage they are just barely warm to the touch after running for many hours. Hopefully this also means a longer lifetime but only time will tell for that.

Great price and they work just like originals ones.

Exactly what I ordered, excellent delivery. Thanks!!

Buying next level in brightness next time. Bought the G4 3W Warm White 2700k 220-260 lumens for my landscape lights and they are not as bright as my comparable halogen bulbs, I need more brightness. The fit is correct (they JUST fit lengthwise) and I am looking to go up to a 4W-5W 450 lumens, still in a warm white 2700 or so kelvins, but the length of these increases and I am not sure they will fit. I will double check on this new length and see if they will fit. Hoping the higher lumens will give me the brightness that I need without going to a bright white ( which I will NOT do because they are too cool and blue). May try Daylight if the Warm White is not bright enough. Otherwise love these.

Great replacement for the incandescent bulbs which look and work great.
