Dear Sirs, Maam,

My name is Ryan Kim, and I'm working for company called Digital Hongil, Co., Ltd in Korea.
We are specialized in Video editing, cameras, and all the other products, including LED studio lights.
You can check our business style at http://www.redsun.co.kr.

We have more than 10 years of experience in this field, and have long and strong relationship with many foreign companies. We are official distributor of Avid technology for Pinnacle Studio series, Media composer, Media networks, and also official distributor of Smartsound Inc. for background musics, Prodad GmbH of Germany for their softwares, and many many more.

We are devleoping studio LED lighting solution using 720 bulbs per unit. We are looking for LED bulbs with following specifications.

5mm, wihite color LED bulbs, color cordinates of X : 0.33~0.36, Y : 0.33~0.36.
Beam Angle : 30~60 degree
CRI : over 75
MCD : Over 3000

The color temperature is very important, since it will be used for video cameras. Wrong color temperature will give green or blue white balance. The output and color ordinate should be uniform quality as narrow as possible


So I hope you give us quotation for 20,000 pcs. and 50,000 pcs. of each models. If we decide to make product with your LED bulbs, just manufacturing 100 unit will require 70,000 to 100,000 pcs. of LED bubls easily.

I will wait gladly for information you will give to us.

Thanks in advance.
