Need your help. (55w=130w 3800k)and(55w=110w 4150k)Which one is bright?They both for driving light H3.Thank you

 

You'll want the higher temperature for brightness. Manufacturers these days are quoting the temperature with the wattage rating to give you an idea of how bright their bulbs are. The higher the temperature the better. These measurement scale was mainly used for HID systems, but now we're starting to see it used for non HID bulbs as well.

 

I just bought the 4150K ones and they are sweet. Bright as hell. I think you will be very satisfied.
