Just got a 4-pack of the Walmart "Great Value" version of these energy-

Are the name brand bulbs of this type any better?
Hi,
What name brand? They are 99% made in China. For more light output try
daylight kind which has higher color temperature.

My expereince is that higher color temp. ones produce slightly less
light than ones rated 2700-3500 K.
Higher color temp. ones do work better outdoors at night however,
because their spectrum is more favorable to night vision.
