G4 LED Bulb, 12V Bi Pin Base, 20W Light Bulb Equivalent 3000K

I gave the brightness & easy to install parts of this review 5 stars because im keeping true to my experience, however i did not rate the longevity portion because ive only had them about a month now. They still work great! The lights are nice and bright yet still have a warm color. I installed them all over my 5th wheel travel trailer. Matter of fact after ordering my first 6 pack, i ordered (2) more 10 packs and covered every bulb inside that fit a G4 bulb. Examples are above my stove, cieling pods throughout the RV, above our lazy boys, above the sink in the bathroom, in our walk in closet etc. You name it.. I pulled every fixture available and replaced them with these bulbs. **THE BONUS IS THEY ARE DIMMABLE** I have now replaced every bulb throughout the rv and around our property outside with LED bulbs (G4, G8, T10 wedge, e27, candelabra, etc. and utilized a assortment of solar powered lights plus installed a timer on our front yard landscape lighting. Though it was a costly investment, it has made a tremendous difference on our electric bill. Trust me when i say..it is definitely worth the initial costs to make these upgrades. Amazing power g4 bulbs played a big part on the inside of our 5th wheel and im extremely satisfied with them. Hope my review was helpful 🙌 ***UPDATE*** July 12, 2023 Still using these lights on a daily basis and not a single one has had any issues. Still very bright and cost effective.

I bought these to replace a failing unit that came with my deck lights although it’s a little smaller in size it’s still looks similar in style and shape and provides adequate light from the fixture. Even though they are described as the same color temperature rating (3000 K) I actually like the color of these a bit better as they are warmer and are closer to what incandescent bulbs look like, which I prefer. These LED bulbs are kind of like the Wild West right now or the proverbial box of chocolates, you never know what you’re gonna get. So far so good.

I had replaced my 20W halogen bulbs with LEDs about 3 years ago in my landscape lighting. The older LED bulbs were not as bright and a bit blue compared to the warm glow of the halogens but at 10% of the electricity cost it was worth it. Some of those bulbs started to dim so I replaced them with these and WOW is there a difference. The color matches the old halogens almost perfectly and they might even be a bit brighter. These bulbs are great so far. These bulbs are encased in plastic but the case is not sealed at the ends. Not sure why they don't seal them but I am using them outdoors and am going to seal one or two to see if it makes any difference (heat / moisture). The light pattern works perfectly in the fixtures I am using them in, but they are dimmer at the edges 90 degrees off the front/back than the halogens are (look at the picture - the bulbs are brightest when looking directly at the face of the PCB in the front and the back.) As stated in the description - they do not work with most dimming 12V supplies, even if the dimmer is set to full brightness. Dimmer compatible LED bulbs have a different/larger/more expensive power driver for the LEDs to prevent the flicker.

Package of five bulbs arrived just fine. Plugged the first one in and no light. Tried same bulb in a different socket, still no light. Checked a second bub and it worked. Tested all five and only the first one did not work so 20% failure rate. Light is nice, soft white that is perfect for ceiling lights in our camper bathroom. Very pleased with the bulbs that worked.

Great little bulb.

Work well

Had to replace several LED bulbs in a boat. Perfect fit and emits lots of light.

Crap! They don't last. Waste of money. We were told LED's were supposed to last 5-10 times longer than halogen lights. One year later these lights lost half of their lights and then burned out. Absolute crap. Stick with halogen or standard light bulbs.

To get these to fit in my kitchen down light fittings I had to cut off the little nubs on the end. But while being just a smidge whiter than the warm glow from the halogens they replaced (really neither here nor there) these are effective and cheap replacements for my old 20w halogens. One gotcha is to check your dc power supply for suitability with LED lights. I have to keep a halogen or two in the string of lights or the power supply doesn’t output power.
