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)

Terrific brightness and color temperature on these lights. Nice warm and bright light. I used this in all of my Gardencoin path lights that I purchased on Amazon... which are also beautiful. These product light that is as bright and possbily brighter than the name brand solos bulbs that I purchased from a local store for 4X the price!!

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.

These bulbs are great. I’ve had them in my landscape lighting for 5 years and they’ve been flawless. I can’t even recall replacing one. I didn’t know what to expect with these in outdoor fixtures exposed to wide temperature swings/heat, and the only precaution I took was some dielectric grease to ensure moisture didn’t corrode the sockets they were plugged into (a problem I experienced with the halogens). Pleasantly surprised by the longevity of these, considering they have run every single night from before sunset to after dawn, every day, in all weather conditions, since installed. They’re sort fit just like the originals, the only difference is the flat base, which was better in my case. The outer covering that the LED array is embedded in is a sort of clear rubber. The circuit inside the bulb also corrects polarity, which is a great feature as you can plug them in either way, just like the incandescent bulbs. I came back to review them not because they have been a problem, but because they haven’t been and I retrofit one of our inflatables with one of these because they happened to be the right voltage and just work. Many “brands” come and go on Amazon, but this one hasn’t. Still the same, still available. Would gladly buy again when I finally run out of them. Probably not any time soon.

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.

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!

I have bought these bulbs multiple times. Besides being LED with low operating cost, they are high quality and long lasting. Great price and fast shipping as well.

They came in on time and they work. Can’t tell how they will last.

Great looking bulb, design and materials - but unfortunately, several of the bulbs only worked for one or two days before going out. I really wanted to like them - especially with the coating around the bulb that seemed to be a great idea for an outdoor product. Hopefully they can fix whatever is causing them to go out so quickly.

Good quality, easy to replace

Such a great price! Lighting stores charge and arm & a leg just for 1 bulb - it's craziness.

They fit my fixture and run bright without the extreme heat of low voltage bulbs

lights encased in silicone... they look they will weather nicely

We bought these for our under counter lights. We replaced the ballast with LED ballasts/drivers. 2 of the 12 bulbs flickered after installation, which only got worse. We left them in for a couple of hours. When I pulled them out, they were extremely hot. Inside the bulb you could see a lot of discoloration, and maybe a damaged capacitor in one of them. We replaced both, and they are working so far. They are much thicker around that I expected, about the same size as a AA battery. They didn't fit in the fixture, so we had to leave the glass off. I didn't pay enough attention to the dimensions, so that is my fault. I don't believe these are very high quality. I would ensure you buy enough for a couple of spares.
