全屋用哂LED照明會不會比用光管更靚聲?

全屋用哂LED照明會不會比用光管更靚聲?

VERY SPECIAL PRICE TO BUY THIS LIGHT Bulb......................

Only for Vendor.

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.
