Which "Government offices for living" are you talking about? There are not many people in the U.S. using LED technology for general lighting, not even our government, who are experts at spending money on things "we" don't need .

If this was a question that could be answered, I would have to ask why you are seeking this information, before I would consider answering.

Hello Tom ,

I am seeking this information because one of my American client (a trader) wants this kind item ,while he is not professional in this field ,so I suppose he can't answer such questions to me , and the fact meets my suppose.

As I know ,most Americans use CWF (Cool White Fluorescent)

the color tempetarure is :4150K ,Power :20W( in shop or office) , and the Lumen , hard to choose , from 2000-15000 LM , The high of the power , more expensive.And hard to Heat Dissipation.

The core of the LED is the chip , which made in China is much more cheaper than in USA like CREE. So I also need to know his target price.Then help him make the choices.

Do business is a hard job , I though work in the government is much comfortable than me .
