全屋用哂LED照明會不會比用光管更靚聲?
本帖最後由 kk_ho 於 2010-6-11 22:21 編輯全屋用哂LED照明會不會比用光管更靚聲? 我正想問這問題，剛好我正準備一家hifi房，現成滿屋光管，到時預暫辦法，開hifi時關光管。 VERY SPECIAL PRICE TO BUY THIS LIGHT Bulb......................
Only for Vendor. 之前在街問過，價錢貴過儉電胆一倍有多，不知現在多少錢？ Some parameter need to consider.
1. lm / watt.
e.g. If the light bulb label is 250lm 5.5W, you can make a simple calculation, around 45lm / watt of this LED.
This is a single dice LED package inside this light bulb.
I found one LED brand in this exhibition, 160lm / watt.(Overdrive 760 lm / watt). You may found this product at the end of 2010.
2. CRI factor (Color reflection index)
Sun light is 100% reference.
This light bulb only claim 75.
What happen is?
Try to use LED lamp bulb project to the "Fruit", you will know what I say.......
100% CRI will result more nature, just like what you see what you get.
75% CRI......... I think you will not interest to buy the "fruit" if you watch that.
Hope this help. 三個不同火數的LED燈，中間那個已爆開了，可以看看內部燈。

轉用我公司LED光管,效果會更好!
有興趣可pm我!
二年保養! PFC value?
Efficiency?
CRI value?
lu/ watt?
Can export to Japan or not? Very good, Today LED lamp efficiency is same as T5 fluorescent or a bit higher, also using switching
mode power supply technology, no good for Hi Fi. Tungsten bulb or halogen bulb are good, they are not
using switching power supply.
They using direct ac or step down by transformer for 12v lamp, do not buy switching dome step down type
(電子火牛). You may try Samsung AC LED. Direct drive from AC 110V / 220V AC source.
