就第一句話我認為是...
改LED路燈有著龐大的"商機"....
另一方面預算編了一定要消耗掉, 不然會被檢討明年
無法再提預算....
跟LED節不節能, 環不環保, 我認為無關～

Philips 有一款 LED 燈泡，皇后之星，825lm/12W =68.75 lm/w 接近一般省電燈泡，
用這款目前佳的產品，可以取代一般省電燈泡，但是絕對不會省錢的，因為一顆要價破千，也不會省電的，因為一顆 12w 的省電燈泡，也能有一樣的流明。
節能、省電、壽命長？...(恕刪)
買LED真的要等一等
今天看頻果日報 PHILIPS有一款E27 12W LED 的叫皇后之星的 賣1499
好像多800Lumens 規格似乎是很好沒有錯
國外賣https://hdsupplysolutions.com/shop/product-led_bulb_philips_12_5w_a19_2700k_dim-458116?rr_cid=458116
現在國外買大約25USD
但是美國今年2012已經出了新款的型號42022-4 E27 10W 940 Lumens 開價USD60

預估一年後會降到25USD

42022-4新的更亮 發光效率更好也只比台灣買得到的舊款皇后之星1499貴一點點
真的是次級品才賣到台灣
但最近持續的詢問 發現Led 崁燈比以前便宜很多 亮度方面也敢善很多
我最近有換幾顆 12W LED 崁燈 (每個300多)
說真的 比原本28W 崁燈還亮
當然我是沒實際下去測亮度啦 但那種亮的感覺是滿明確的 (桌面喔)
至於容不容易壞 (從3W 的觀察用1年多是沒壞過 但t5 燈管跟28W 螺旋已經換好幾顆了 我是聽說 led 可能最先壞的會是變壓器 所以耗材成本可能變壓器會比較可能)
Led 感覺也有持續在進步 而且價格也持續在降 當這波量起來後 慢慢可能會落到比較合理的價格
大家持續的等等啦
不過,有可能這些國家的電費真的太太高了,所以讓LED更吸引人.日本的合理LED燈泡價格居然在US$25啊..

Digitimes Research projects that the global high-brightness LED industry will see year-on-year growth of 13.4% in 2012, with output rising to US$10.1 billion.....
The LED light bulb market will continue to grow rapidly in 2012, with new products largely consisting of replacements for 60W incandescent bulbs. It is worth noting, however, that the price of 60W replacement bulbs with a brightness of 800lm currently remains high at around US$40. Moreover, the "sweet spot" in terms of pricing versus demand differs widely between regions, from US$25 in Japan and US$15 in Europe and North America, to as little as US$7 in emerging nations......
Japan has set a 2015 target for LED lighting as a proportion of the general lighting market of 50%, while South Korea has set a 2015 target of 30% and China has set a 2015 target of 20%.......(恕刪)
