TAIYALOO G4 LED Bulbs, 5W Bi-Pin G4 Base LED Bulb Equivalent to 40W T3 JC Type G4 Halogen Bulb 40W, Not-Dimmable AC/DC 12V G4 Bulb, 360°Beam Angle Warm White 3000K G4 Light Bulb (6 Pack)

I bought these for garden lights to replace ones that had gone out. They fit perfectly and are nice and bright and a fraction of the price of store bought ones. Fantastic bulbs, fast shipping too.

G4で最も明るいLEDを探し求めて購入しました。キジマの4灯ペンダントライトに使っています。本当は60w相当の明るさがあればいいんですが、この40w相当がG4の限界で、多分売られている商品で私の知る限りいちばん明るいです。400lmくらいかなと思っています。これまでは350lm表記の物を使っていましたが、少し明るくなった気がします。 難点は、ちょっと大きいので消灯時に電球そのものが少し目立ちます。あと白熱灯ほどでは無いですが、まぁまぁ熱くなります。 日本語のレビューがほとんど無かったので少し不安でしたが、時間はかかりましたがちゃんと届いたしきちんと使えました。 800lmと書いてあるのに全然明るくないもの（推定200-300lm程度）や、1000lmと書いてあるけど点灯しない物など、Amazonで粗悪品に何度が当たりましたが、これは大丈夫だと思います。（粗悪品はAmazonカスタマーサポートでどちらも返金してもらいました）長期使用の耐久性はまだ分かりません。 600lm以上をこれからも探し続けますが、しばらくはこちらをリピですね。

Bought theses years ago still all are bright, pleasing light temperature. Excellent replacement for halogens but need to replace halogen transformer with led transformers. Don’t flicker at all, instant on. Make sure you use G4 led socket as well

Can’t yet review longevity but fantastic color temperature and brightness. Bought six as replacements for 20 watt halogens. Should have done this years ago.

I purchased these bulbs to replace an old dim incandescent light in an over-the-stove range hood in my RV. My goals were simple: (1) Get brighter cooking area on stove (2) Keep good color balance for indoors. I have to say these bulbs performed perfectly. I installed them in my range hood and the difference compared to the old bulb was like night and day. These are brighter and have a more pleasing color. I really like the 3000K color balance. I had earlier tried a 2700K, but it was too yellow, and I don't like the cool white (5000-6000K) because it's too harsh, almost blue. These bulbs (3000K) strike a perfect balance. One interesting feature these bulbs have is that they have internal electronics (bridge rectifier, I believe) to get the DC polarity correct for the LEDs, so there is no + or - terminal, you can plug them in either direction and they work fine. One other thing to note is that these bulbs are not dimmable. That was not an issue for me. I'm using them over a stove, and I want them either ON or OFF. I'm not trying to strike a specific mood for cooking by dimming the lights. So my summary: These LED bulbs met or exceeded all my expectations, I'm happy with them and would buy them again.
