I have heard that actually C7’s LED Christmas lights are brighter than LED C9’s even though they are smaller. Does anyone know for sure? Thanks! A: There are many styles of LED lights including sizes of the bulbs. Depending on if they are full wave or half wave also contributes to the performance of the lights. In addition, there are many differences between manufacturers and brands. In other words, not all LEDs are the same. LED’s are sometimes a single bulb, and others are a series of bulbs all packed into a C-7 or C-9 container. I have used Home Depot Brand C-9s and they are okay – not the best, but they were given to me so I do not think that much about it. If you are talking about the C-9s that can be replaced, I woud disagree as they are very bright. But if you really want to get the expert opinions, I would ask the members of these forums: http://talk.planetchristmas.com http://doityourselfchristmas.com/forums/index.php http://www.synchronizedchristmaslights.com/forum/ two LED v
