Review: 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.
Review: 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、desertcart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desertcart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。
