Economic type, 10 flat bright enough. Mainly power saving???

Express speed pretty fast, received a very good brightness after installation, installation is simple.
This dome is really good, thank you, the seller will always patronize....


Things have not received, out of the box, installed after coming after assessment
Huang Baiguang color is very good, feel more comfortable than white eyes.
Too few dollars, even the postage is not enough. Not yet installed so I do not know is not good, and then installed a good review! I'll buy your house!
