Just wondering what the diffrence is. I hear that a lot of people are switching over to T5 and they are better than PC because they are more powerful and have more lumens. What do you guys think? I couldnt find any info on the web anywhere. People compare WPG but I hear that with T5 that doesnt really apply because for like a 56 watt T5 is equivalent to something like a 130Watt PC.
