ＬＥＤ電球へ交換④－浴室（密閉形器具対応） ― 2011/04/24 17:09
ＬＥＤ電球への交換が止められません・・・。
今回は、浴室です。
家族４人が入浴すれば、１日の点灯時間もそれなりです。
なので、それなりの省エネになるのではないでしょうか。
浴室のＬＥＤ電球への交換で、一番頭を悩ましていたのは、「密閉形器具対応」である事です。
未対応のＬＥＤ電球に比べたら、種類も少なく、また明るさ（ルーメン）も小さめ、そして、価格は高め、という印象です。
いくつかの製品に目を付け、価格の動向を探っていたところ、なかなか良い値段になったので、購入しました。
「ＳＨＡＲＰ ＤＬ－ＬＡ３２Ｌ」
価格 ￥１，３３０．－（ただし、送料は別）
全光束 ３８０ルーメン（電球色）
消費電力 ７．５Ｗ
例によって、独自の指標による性能を算出してみます。
１００ルーメン当たりの価格は、￥３５０とやや高め。
１ルーメン当たりの消費電力は、約１９．７ｍＷと、こちらもやや高めです。
電球色は、昼白色に比べて、同じ消費電力でも、全光束が小さい傾向があるので、仕方がありません。
しかし、玄関（センサー）と、トイレに使ったＯＲＩＯＮ製の調光器対応のＬＥＤ電球も、電球色ですが、１ルーメン当たりの消費電力は、約２０．３ｍＷですから、このＬＥＤ電球の方が、若干ですが効率は良いようです。
ちなみに、それまで付けていたのは、電球型蛍光灯１２Ｗ（推定全光束８１０ルーメン）です。
全光束の違いが大きいので、明るさに不足を感じるかもしれませんが、今のところ、私の見る限りではわかりません。
例によって、家族には内緒で交換したので、その反応で分かるのではないでしょうか。
ＬＥＤ電球は、電球型蛍光灯と違い、スイッチオンで直ぐに明るくなるので、そこで気づく可能性はありますが、我が家の家族は結構無頓着なので、こちらから言わないと、きっといつまでも気づかないでしょう・・・。
実際、リビングの変化には、いまだに気づいていません。というか、既に今の明るさに慣れているはずなので、今更気づくとは思えませんね。

I think what you said made a ton of sense.
But, what about this? what if you composed a catchier post title?
I am not suggesting your content is not good., but suppose you added a post title that grabbed
a person's attention? I mean ＬＥＤ電球へ交換④－浴室（密閉形器具対応）:

post titles to get people to click. You might add a related video or a picture or
two to get people interested about everything've written. In my opinion, it might bring your posts a little livelier.

but I can figure things out pretty quick. I'm thinking about creating my own but I'm not sure
where to start. Do you have any points or suggestions?

First of all I would like to say wonderful blog! I had a quick question that I'd like to ask if you don't
mind. I was interested to know how you center yourself and clear your thoughts prior to writing.
I have had a difficult time clearing my thoughts in getting my thoughts out.
I truly do enjoy writing however it just seems like the first 10 to
15 minutes tend to be wasted simply just trying
to figure out how to begin. Any suggestions or tips?
Many thanks!
