白燈是色溫大約6000-6500K,黃燈是色溫大約3000-2500K,色溫只是燈光的color而已,所以色溫並不影響用電量。而要選擇慳電的照明產品,其實應該看wattage(瓦數),瓦數越少越慳。例如同樣長度的光管,舊款的T8,T12用電量本相對新款的T5較高;當然還有LED燈泡,(LED燈泡的光度是烏絲燈泡的5至10倍) 更慳電更耐用,一般都可用上萬小時

我覺得睡房放黃燈 - 昏昏暗暗,快D瞓著;要做嘢的地方當然放白燈 - 醒神D!

夏天用藍白 冬天用黃紅 秋天用綠    想有感情用 紅色 想有溫暖用 黃色  想有空廣用 藍色 想有清潔用 白色 唔想見光用 黑色

用電唔關白燈定黃燈事, 係睇walt數, 白燈睇野米清楚d, 所以書房多數用白燈, 黃燈柔和d, 通常用在客,飯廳

我都中意白燈,睇書好D

但最近裝修,主人房試下用黃燈,用落都幾舒服

小朋友房記住用白燈,讀書溫習對雙眼好D

唔同既燈係要配合環境而用既~白燈適合書房, 黃燈休息時唔會太刺眼~至於慳電,就睇你係咪用慳電膽或者led燈jei, 如果用烏絲燈就最浪費電力

白燈望上去會光d,黃燈則比較柔和。兩隻用電差唔多。
