G4 LED Bulb Dimmable 2W Equivalent to 20W
G4 LED Bulb Dimmable 2W Equivalent to 20W
Key Features
- 【120V G4 LED Bulb】This G4 bulb operates at 110–130V; do not use it with 12V–24V low-voltage systems. It emits a soft, warm white light of 3000K with 240 lumens and a Color Rendering Index (CRI) of 85+, creating a cozy atmosphere in living rooms, bedrooms, and dining rooms.
- 【90% Energy Saving】The 2W G4 LED bulb (AC110-130V) replaces traditional 20W-30W halogen bulbs, cutting your electricity bills by up to 90% while producing far less heat. It delivers energy-efficient, high-quality light output, ensuring 30,000 hours of long-lasting performance for reliable use in landscape, cabinet, and ceiling fixtures.
- 【Dimmable Control】This dimmable G4 LED bulb lets you adjust brightness using a compatible LED dimmer to achieve either bright or dim lighting effects. It is essential that the dimmer is capable of functioning properly with low-wattage LED bulbs. No flicker, buzz, or glare—perfect for setting the mood in ceiling lights, wall sconces, and landscape lighting.
- 【Wide Application】This G4 LED bulb features a standard 2 bi-pin base design for easy installation. This bulb fits all G4 sockets, including table lamps, ceiling fixtures, under-cabinet lights, landscape lighting, courtyard, garden, puck lights, under cabinet lighting, post lights, and recessed light. It works for both residential and commercial use.
- 【Important Purchase Notes】This 110–130V household voltage G4 LED bulb needs no transformer. Size: 1.3 × 0.59 in (33 × 15 mm), slightly bigger than standard halogen bulbs — confirm fixture fit first. It only fits G4 sockets, incompatible with G8/GY6.35/G9 bases and all 12V low-voltage setups; double-check your fixture’s base and voltage before ordering.

Compared to the original halogen bulbs, these are great replacement bulbs. It's just as bright but it's energy efficient and cool (temperature). No complaints except that it is larger in size compared to halogen bulbs. If you have a tight spot, this may not be good for you. Otherwise, it is great replacement bulbs.

I ordered these to replace the halogen bulbs in my under-cabinet lighting, but I quickly discovered that I had measured incorrectly. I've never replaced these bulbs before, so I wasn't familiar with the different bi-pin sizes. It turns out I needed G8 bulbs, not G4.The difference between the two sizes is surprisingly small, which is why I'm including photos for anyone else trying to figure out which bulb they need. A quick glance can make them look very similar, but they're definitely not interchangeable. Since the sizing error was entirely mine, I'm not deducting any stars. The bulbs themselves appear well made, and the ceramic base construction is much nicer than some of the cheaper LED replacements I've seen.Rather than return them, I'm keeping them because my husband believes he can use them in lighting fixtures in his workshop. If you're shopping for replacement bulbs, double-check your existing bulb size before ordering. Hopefully, my photos will save someone else from making the same mistake I did!

I used these G4 LED bulbs while converting my landscape lights from solar to a wired setup, and the difference is night and day — literally. They’re bright enough to make my yard look like it finally got its life together, and the 3000K warm white gives everything a clean, welcoming glow.The bulbs themselves are tiny, sturdy, and feel well‑made, which is great because some of my fixtures have all the elbow room of a sardine can. They fit perfectly and fire right up.Now, the reason for four stars:They’re a bit pricey, and they run hotter than I expected for LEDs. Not “call the fire department” hot, but definitely “don’t touch me after I’ve been working” hot. Still, they’ve been reliable and look fantastic in the yard.If you’re upgrading from solar lights and want something brighter, cleaner, and more durable, these bulbs are a solid choice — just be ready to pay a little extra for the glow‑up.

They work well. the brightness is not over bearing thankfully. they were easy to install. Dimming works well and doesnt seem glitchy. Their size is small but not too small. The dome is made of a glass material which i presume is something like pyrex but im not 100% sure. Either way im happy i ordered them because i can actually see around the room now!

G4 LED Bulb Dimmable 2W Equivalent to 20W-30W Halogen,AC110V-130V 3000K Soft Warm White T3 G4 Bi-Pin Ceramic Base for Landscape, Cabinet, Ceiling Lights, 10 PacksI am using these to replace 3x halogen bulbs using 20W @12VAC and 260 lumens each, which are typically 2700K color temperature. And I approached this purchase with skepticism after a poor experience with another brand of 12VAC LED in this same fixture. Also, I intended to convert the fixture to 120VAC by bypassing the transformer, so these LEDs were selected accordingly.These new LEDs have a form factor similar to the original halogens, and are definitely much smaller than that other brand I tried - that's a plus for many fixtures.Brightness is equivalent to the ones I removed, so the claimed 240LM is realistic. Color temperature seems about right, too. The white balance in my photos is not calibrated, and the glass shades in this fixture are tinted a bit warmer than the bare bulb. The overall light effect from this fixture is similar to the original halogen or a 60w soft-white incandescent, and a bit warmer than a different 3000K LED fixture in the same room.Because this LED bulb has multiple emitters, the backscatter pattern on the wall above the fixture is different than a single filament halogen. Different, but I kinda like it. I did not have a chance to test these with a dimmer, but they are solid using full waveform line voltage (no flicker).The price point for these bulbs is a bit high, but with 1/10th the power consumption, you'll pay it back eventually, ha!

Great super bright little lamps according to the package, they say they are dimmable and these are going to come in handy for some projects that I have planned.

These are exactly what they advertise themselves to be. The bulbs seem very well made, and they do in fact use a ceramic base, which gives them a more premium and durable feel compared to cheaper alternatives.The light quality is great, and overall they feel like a high-quality set of LED bulbs.One detail I especially appreciated was the packaging. The bulbs come in an electrostatic-style protective bag, and each individual bulb is separately packaged inside, which is excellent for storage and helps prevent damage during shipping.Overall, this is a very solid product with good build quality and thoughtful packaging. Easy 5 stars.

I only needed three G4 bulbs to replace the lights in my microwave oven, but buying just three name-brand LED replacements would have cost more than this entire 10-pack--so this set was an easy choice. I can't tell whether they'll last as long as the pricier bulbs, but even if they don't, I can replace every bulb a couple more times and still have an extra left over.The light output is very nice—a warm white color and actually brighter than the old halogen bulbs these replaced. My microwave has two brightness settings for the over-the-range cooktop lighting, and these don't flicker or buzz at all on the high setting, but do flicker slightly (barely noticeable, to me) on the low setting.Note that these bulbs are much larger than the original halogens. The fit was a bit tight in my microwave, and installing them while crouched underneath the unit wasn't much fun—especially with fat fingers. It took a while, but I managed to get them installed OK.Even though only one bulb had actually failed, I went ahead and just changed all three, including the one inside the microwave oven.What I don't like about them is that the bulbs have no identification markings—only the box does. Not a big deal, but I prefer bulbs to have at least basic specs printed on them for future reference. I also find it odd that the base is porcelain for high heat, yet the clear dome over the LEDs is plastic.Overall, these are bright, warm, dimmable, and affordable replacement bulbs that worke well for my microwave. Good value.
