~ Bola lampu Hemat Energi Tahan 20 Tahun

WASHINGTON DC, (PRLM).- Pemerintah AS meluncurkan sebuah bola lampu revolusioner yang paling hemat energi dan bisa awet selama 20 tahun.

Bohlam ini dikembangkan setelah Kongres meluncurkan kompetisi L Prize $ 10 juta pada 2007 untuk menemukan bola lampu untuk menggantikan lampu pijar boros energi 60 watt.

Namun ketika hanya produsen Philips dari Belanda yang mengikuti kontes, maka dinyatakan sebagai pemenang dan mulai bekerja.

Bohlam yang semestinya memancarkan cahaya alami yang menyenangkan ini, akan dijual di Home Depot dan outlet lainnya dimulai pada hari Minggu, Hari Bumi.

Harganya $ 60 yang mencerminkan biaya dari komponen, terutama chip, atau dioda yang mengeluarkan cahaya.

Namun Philips akan memberi diskon menjadi $ 50 untuk konsumen, dan diskon sebesar $ 20 sampai $ 30 bila kerjasama dengan perusahaan listrik.

Seperti dilaporkan Mail Online, bola lampu hemat energi ini menjadi investasi yang baik dibandingkan dengan lampu pijar. Hanya menggunakan 10 watt, artinya menghemat sekitar $ 8 per tahun jika digunakan empat jam sehari. Bohlam ini diharapkan bertahan setidaknya 30.000 jam, atau 30 kali lebih lama daripada lampu pijar. Bila dinyalakan empat jam per hari, itu berarti selama 20 tahun
