LED電球を買わずにはいられない ― 2011/04/10 19:18
先日、書き込みをしたように、玄関灯(センサー付き)を、LED電球に交換しましたが、実は、これと同じものをもう一つ同時に購入していて、どこに使おうか迷っていたのですが、点灯を繰り返すことが多い「トイレ」に使っています。
その後、実家の親に頼まれた物を含めて、4つのLED電球を購入し、とりあえずそのうちの一つを、リビングに使用。残りの3つ、または2つは実家で使用する予定なので、もう一つ、我が家で使う可能性もあります。
更に今日、たまたまスーパーの電気コーナーで特売品を発見し、悩んだ挙句、1つ購入。
少し古い型だと思いますが、SHARP製の「DL-L601N」という、全光束560lm、定格消費電力7.5Wという、最新の型ほどではないにしても、そう悪いものではなさそうです。
それが、なんと¥1,280でした。
先ほど、試しに付けてみたら、それがなかなか良いではないですか。
在庫限りの処分品なので、無くなれば終了です。
明日にでも、もう1つ2つ買ってしまいそうな・・・・。(LED電球貧乏になりそう・・・。)
これら、LED電球については、それぞれ個別に紹介したいとも思っています。
そうそう、一つ考えたのが、LED電球のコスト・パフォーマンスを量る指標のようなものができないものかと。
やはり、全光束と価格が重要なので、その比率で考えてみます。
そこで、光束100ルーメン(lm)当たりの価格を算出してみます。(価格 ÷ 全光束 × 100 という計算ですね。)
上記のSHARP製については、
¥1,280 ÷ 560lm × 100lm ≒ ¥229
ということになります。
恐らく、¥300を下回る製品はなかなか無いと思いますよ。
※4/17訂正
光束100ルーメン当たりの価格計算の式が、分かりにくかった(回りくどかった)ので、訂正しました。(その他、誤記訂正あり。)

I'm assuming having a blog like yours would cost
a pretty penny? I'm not very internet savvy so I'm not 100%
certain. Any suggestions or advice would be greatly appreciated.
Appreciate it

I'm going to start my own blog in the near future
but I'm having a hard time deciding between BlogEngine/Wordpress/B2evolution and Drupal.
The reason I ask is because your design and style seems different
then most blogs and I'm looking for something completely
unique. P.S Sorry for getting off-topic but I had to ask!

However, what about this? suppose you were to create a killer headline?
I ain't suggesting your information isn't solid., however what if you added a title to
maybe get folk's attention? I mean LED電球を買わずにはいられない: まだ文字もない頃の日本と日本人、日本語が気になる blog is a little boring.
You should peek at Yahoo's home page and watch
how they write post headlines to get viewers interested.
You might try adding a video or a picture or two to grab readers interested about what you've written. Just my opinion, it would make your
blog a little livelier.
